In recent years, we have started to look at health from a different perspective. For a long time, the goal was clear: prevent disease and extend lifespan. However, this approach falls short when we try to understand what actually happens in the body over time.

The reality is more nuanced. A person may have no diagnosis and yet have already begun to lose part of their physical, metabolic, or cognitive capacity. This is not a sudden or obvious change, but a gradual process that often goes unnoticed for years.

Dr. Carlos Martí – Neolife Medical Team

It’s Not Just About Being Healthy, but Understanding How Your Body Functions

When we think about health, we usually reduce it to the absence of disease. However, this perspective does not reflect how the body truly evolves over time.

Each system in the body has a point of peak performance, typically reached in relatively early adulthood. From that point onward, a gradual decline begins—one that is not always immediately noticeable. This is not an abrupt change, but a progressive reduction in function that affects multiple levels: physical capacity, metabolic function, cognitive performance, and immune response.

In this context, the concept of Peakspan has been introduced. It refers to the period during which the body remains close to its maximum functional potential, typically within a range near that peak. It is not about how long we remain disease-free, but how long we can maintain a high level of functioning.

What is particularly relevant is that this period is much shorter than we intuitively assume. Although life expectancy has increased significantly, most physiological functions begin to move away from their optimal point decades before any disease or clear clinical limitations appear.

The Silent Decline: When the Change Really Begins

One of the most important insights is that loss of capacity does not coincide with the onset of disease. Between these two points, there is a long period during which the body is still clinically “healthy” but already functioning below its optimal level.

This decline begins earlier than we tend to think. Many functions reach their peak in the third decade of life and then gradually decline. Initially, this is not clearly perceived, but it manifests through subtle changes: reduced endurance, slower recovery after exertion, decreased adaptability to stress, or more frequent infections.

This leads to what can be described as a state of being “healthy but with reduced performance,” where no diagnosable pathology is present, yet there is a growing gap from maximum functional potential.

As a result, two individuals with similar lab results may be at very different stages of this process. One may still be functioning close to their peak, while the other has already moved significantly away from it—even though both are considered clinically healthy.

Understanding this decline as part of the process allows for earlier intervention. The goal is not to wait for abnormalities to appear, but to identify when capacity begins to decrease and how it evolves in each individual.

When the Body Really Starts to Change

When different physiological functions are analyzed separately, as described in recent research on Peakspan, a clear pattern emerges: there is no single starting point for aging, but multiple trajectories that begin earlier than we typically perceive.

In the cognitive domain, abilities related to processing speed and working memory peak between the ages of 20 and 30, and then begin to decline, while other skills linked to experience are maintained for longer.

At the cardiorespiratory level, aerobic capacity and lung function reach their peak in the second or third decade, followed by a gradual decline. Similarly, muscle strength and mass peak between the ages of 20 and 35, with a period of stability before a more noticeable decline begins.

Other systems also show early changes. Kidney function begins to decline as early as the third decade, the endocrine system experiences gradual hormonal decreases from mid-adulthood, and the immune system shows reduced responsiveness from early adulthood.

Sensory and digestive systems follow a similar pattern, with changes appearing earlier than expected, such as high-frequency hearing loss or alterations in gastrointestinal motility and liver function from midlife onwards.

Overall, functional aging is an early and non-uniform process, in which different systems move away from their optimal state long before diseases or evident limitations appear.

Maintaining Capacity for as Long as Possible

This shift in perspective requires redefining what we mean by prevention. It is not only about avoiding disease, but about intervening in the functional trajectory before the decline becomes established.

The value of the Peakspan concept lies not only in describing the problem, but in identifying the point where there is the greatest opportunity for intervention: when function begins to move away from its near-optimal range. Acting at this stage allows us to modify the rate of decline and extend the period during which different systems maintain high performance.

This approach requires a more precise assessment, focused not only on isolated parameters but on the integration of functional, metabolic, and structural data to understand where each patient stands. The combination of biomarkers, functional testing, and lifestyle assessment provides a more complete view of this trajectory.

At Neolife, this model is part of daily clinical practice. Evaluation is aimed at early identification of which systems have begun to lose efficiency, followed by targeted interventions on the underlying mechanisms. This includes addressing cardiorespiratory capacity, muscle mass, metabolic balance, hormonal function, and sleep quality—all key determinants of functional capacity over time.

The goal is not only to delay the onset of disease, but to sustain the highest possible level of functioning for longer. This is the true paradigm shift in longevity medicine.

What intermittent fasting is, how it works in the body, its potential benefits, and the risks of applying it incorrectly.

Intermittent fasting has become one of the most popular nutritional strategies in recent years, especially among individuals looking to lose weight. While it can offer metabolic and health benefits, it is not without risks if practiced without proper knowledge or supervision.

Adriana Martín Peral – Neolife Nutrition Unit

What Is Intermittent Fasting?

Intermittent fasting is not a diet per se, but rather an eating pattern that alternates periods of food intake with periods of fasting. It focuses less on what you eat and more on when you eat. Unlike traditional diets, it is not based on restricting specific foods, but on structuring the timing of meals.

Main Types of Intermittent Fasting

16:8 Fasting

This involves fasting for 16 hours and concentrating food intake within an 8-hour window. It is the most popular protocol due to its ease of integration into daily life.

14:10 Fasting

A more flexible version, recommended for beginners or individuals with higher energy demands.

5:2 Method

Five days of normal eating and two non-consecutive days with significantly reduced caloric intake.

Alternate-Day Fasting

Alternates days of normal eating with days of complete or partial fasting. It is more demanding and less sustainable for many people.

How Does Intermittent Fasting Work in the Body?

During the first hours of fasting, the body uses stored glucose in the form of glycogen. Once these reserves are depleted, it begins to rely on body fat as a source of energy.

This process is accompanied by:

• A decrease in insulin levels
• An increase in glucagon
• Activation of cellular repair mechanisms

These changes explain many of the effects associated with intermittent fasting.

Positive Effects of Intermittent Fasting

When properly implemented and adapted to the individual, intermittent fasting may offer several benefits:

1. Improved Insulin Sensitivity

Lower insulin levels promote better blood glucose control, which may be beneficial for individuals with insulin resistance or risk of type 2 diabetes.

2. Fat Loss

By promoting fat utilization as fuel, it may contribute to weight loss, especially when combined with a balanced diet.

3. Metabolic Health

Some studies associate intermittent fasting with improvements in markers such as cholesterol, triglycerides, and blood pressure.

4. Possible Activation of Autophagy

Fasting activates cellular recycling processes known as autophagy, which are linked to cellular health and longevity, although their impact in humans is still under investigation.

Negative Effects if Done Incorrectly

Intermittent fasting is not suitable for everyone, and improper implementation may lead to adverse effects:

1. Nutritional Deficiencies

Reducing eating windows without proper planning may result in insufficient intake of protein, vitamins, and minerals.

2. Digestive Issues and Fatigue

Skipping meals without prior adaptation can cause dizziness, weakness, constipation, headaches, or gastrointestinal discomfort.

3. Unhealthy Relationship with Food

In some individuals, it may promote disordered eating behaviors, binge eating, or a rigid relationship with food.

4. Not Recommended in Certain Cases

It is not advisable for:

• Pregnancy and breastfeeding
• Individuals with eating disorders
• Individuals with eating disorders
• People with certain medical conditions without professional supervision

Common Mistakes When Practicing Intermittent Fasting

• Overeating during the eating window
• Prioritizing ultra-processed foods
• Not meeting protein requirements
• Forcing excessively long fasting periods
• Ignoring the body’s signals

Recommendations for Safe Intermittent Fasting

• Start gradually (14:10 before 16:8)
• Prioritize fresh, nutrient-dense foods
• Maintain proper hydration
• Adapt fasting to lifestyle and activity level
• Consult a nutrition professional

Conclusion

Intermittent fasting can be a useful tool within a healthy eating approach, but it is not a universal solution. Its success depends on the individual, the context, and proper nutritional planning. When practiced with knowledge and supervision, it may provide benefits; when applied incorrectly, it can lead to more harm than good.

The recently published American guidelines for the management of dyslipidemia reinforce an important shift in how we understand cardiovascular risk. This is not so much about new targets, but about a more precise way of interpreting what is actually happening in each patient.

For many years, dyslipidemia has been understood as an alteration in numbers: elevated LDL cholesterol implied increased risk, and reducing it was the primary treatment goal. While useful, this approach oversimplifies a much more complex process.

Dr. Carlos Martí – Neolife Medical Team

Cardiovascular Prevention

For a long time, the focus has been on identifying out-of-range values. However, we now know that the atherosclerotic process (the accumulation of fat in the arteries) begins long before these values change or symptoms appear.

This explains why some individuals experience cardiovascular events despite having apparently normal blood tests, while others with elevated levels remain stable for years. The difference lies in what is not always visible in conventional testing: particle number, cumulative burden, or the presence of subclinical disease. Today’s tools allow access to this information and enable a better understanding of where each patient stands in the disease process.

The goal, therefore, is not only to detect abnormalities once they become evident, but to interpret earlier signals that allow for more proactive intervention. In cardiovascular health, it is not just about treating risk when it appears, but about understanding how it develops from much earlier stages.

Beyond Cholesterol: Understanding What We Really Measure

LDL cholesterol has traditionally been the cornerstone of diagnosis and treatment. However, not all LDL particles have the same impact, and a normal value does not guarantee low risk. In this context, apolipoprotein B (ApoB) has gained importance. It is a protein present in all particles capable of forming plaques in the arteries, meaning that measuring it is essentially counting how many “potentially harmful particles” are circulating in the bloodstream.

Unlike LDL, which measures how much cholesterol these particles carry, ApoB indicates how many particles are actually present. This is particularly useful in individuals with overweight, diabetes, or elevated triglycerides, where LDL may appear normal despite high risk.

But not all risk depends on lifestyle or metabolism. There is also a genetic component that may go unnoticed in standard blood tests. This is where lipoprotein(a), or Lp(a), becomes relevant. It is a particle similar to LDL but with unique characteristics that make it especially atherogenic (more likely to promote plaque formation in the arteries). Its levels are largely genetically determined, meaning a person may have elevated Lp(a) from birth without knowing it. As a result, even with apparently normal cholesterol levels, cardiovascular risk may be higher than expected if Lp(a) is elevated. For this reason, current guidelines recommend measuring it at least once in a lifetime.

The integration of these biomarkers provides a more comprehensive assessment of risk, moving beyond a model based solely on total cholesterol or LDL.

From Estimating Risk to Detecting Disease

Another key change reinforced by the new guidelines is the use of imaging techniques to refine risk assessment in selected patients. Coronary artery calcium (CAC) measures the amount of calcium deposited in the arteries of the heart. Its presence indicates that atherosclerosis already exists, even in the absence of symptoms.

Although not yet part of the main guideline recommendations, carotid ultrasound allows direct visualization of the neck arteries and the detection of plaques or arterial wall thickening (intima-media thickness, IMT, a marker of arterial health). While CAC identifies more advanced disease, carotid ultrasound can provide information about earlier stages of the process.

At Neolife, these tools are part of an advanced preventive medicine approach. This allows for more precise adjustment of treatment intensity and prioritization of interventions in patients who might otherwise appear low-risk based on conventional testing.

We combine biomarkers such as ApoB and lipoprotein(a) with imaging techniques, including carotid ultrasound, to obtain a more complete picture of vascular health. The goal is not only to estimate future risk, but to determine whether the disease process has already begun—even in its earliest stages.

A More Precise, Not More Complex Approach

The evolution in dyslipidemia management does not mean performing more tests on every patient, but rather selecting more effectively which information is needed in each case.

In practice, this translates into:

• Knowing when a basic blood test is sufficient
• Identifying when measuring ApoB or lipoprotein(a) is useful
• Considering markers such as high-sensitivity CRP (an indicator of low-grade inflammation), which can increase cardiovascular risk even with normal cholesterol levels
• Using imaging tests to clarify uncertainty about actual risk
• Adjusting treatment based on the patient’s overall profile, not just a single value

This approach allows for the identification of high-risk individuals who might otherwise go unnoticed with conventional testing, while also avoiding unnecessary treatment in those who do not need it.

At Neolife, this strategy has long included the assessment of low-grade inflammation, understood as a key factor in the development of atherosclerosis. It is not only about how much cholesterol circulates, but about the environment in which that cholesterol acts.

Applying a Comprehensive Strategy: Addressing the Cause, Not Just the Numbers

Lifestyle interventions remain the foundation of treatment, but their impact goes far beyond lowering cholesterol. Reducing visceral fat (fat stored around organs), improving insulin sensitivity, engaging in strength training and aerobic exercise, and ensuring adequate sleep all directly influence the formation of atherogenic particles, inflammation, and arterial health.

This explains why two individuals with the same cholesterol levels may have completely different risks. The goal is not just to improve lab results, but to modify the metabolic environment in which the disease develops.

Understanding Risk Before It Becomes Visible

Cardiovascular risk does not appear suddenly—it develops progressively over time. We now know that the atherosclerotic process begins long before laboratory values change or symptoms arise. This is why a conventional blood test does not always reflect true risk. Factors such as particle number, inflammation, and subclinical disease can make a critical difference. The real advancement lies in being able to access this information and understand where each patient stands in the process, allowing for earlier and more effective intervention.

At Neolife, this approach is part of daily clinical practice: integrating advanced laboratory testing, biomarkers, and vascular imaging to detect risk before it becomes clinically apparent and to address it in a personalized way.

Because in cardiovascular health, the goal is not simply to act in time—but to prevent the problem from developing in the first place.

Osteoporosis and osteopenia are silent diseases that affect millions of people, especially as they age.

Diet, lifestyle, and certain daily habits play a key role in both their prevention and progression. In this article, we review what happens in the bones, which nutrients help protect them, and which foods should be limited to preserve their strength.

Meritxell Massons – Neolife Nutrition Unit

What Are Osteoporosis and Osteopenia?

Osteoporosis is a disease characterized by the progressive loss of bone mass and bone quality. The bone becomes more porous and fragile, significantly increasing the risk of fractures, even during everyday activities such as walking or bending down.

Osteopenia is a previous stage in which bone mineral density is lower than normal but does not yet meet the diagnostic criteria for osteoporosis. It is usually detected through a bone densitometry test and represents an important opportunity for prevention.

Why Do Bones Weaken With Age?

Bones are not static structures; they are constantly being renewed. Some cells build bone (osteoblasts), while others break it down (osteoclasts).

• Childhood and adolescence: bone formation predominates.
• Adulthood: a balance is maintained between formation and degradation.
• After the age of 50–60: degradation exceeds formation, especially after menopause due to the decline in estrogen levels.

This process explains why osteoporosis is more common in postmenopausal women and older men.

Preventing Osteoporosis Through Nutrition

Prevention begins long before symptoms appear. Achieving a good peak bone mass during adolescence and early adulthood is essential for long-term bone health.

Calcium: The Structural Basis of Bone

Adequate calcium intake prevents the body from extracting calcium from bones to maintain vital functions such as muscle contraction or blood clotting.

Main sources:

• Dairy products (milk, yogurt, aged and semi-aged cheeses)
• Legumes, nuts, and seeds
• Small fish eaten with bones (such as sardines)
• Vegetables such as broccoli
• Fortified foods (plant-based drinks, cereals)

Two daily servings of dairy products, within a varied diet, usually cover the needs of healthy adults.

Vitamin D: Essential for Calcium Absorption

Vitamin D allows calcium to be properly absorbed in the intestine and deposited in the bone.

Main sources:

• Moderate sun exposure
• Oily fish
• Eggs and dairy products
• Fortified foods

During winter or in individuals with limited sun exposure, deficiencies are common, and supplementation may be necessary under the supervision of a healthcare professional.

Physical Activity: An Essential Stimulus

Exercise, especially weight-bearing activities (walking, climbing stairs, dancing, or strength training), stimulates bone formation. Each muscle contraction sends a positive signal to the bone, helping maintain its density.

Nutrients That Support Bone Health

In addition to calcium and vitamin D, other nutrients play key roles:

• Protein: necessary for the bone matrix, although excessive intake from animal sources should be avoided.
• Magnesium: supports bone mineralization and hormonal activity.
• Zinc: involved in the formation and repair of bone tissue.
• Vitamin C: essential for collagen synthesis.
• Vitamin K: regulates calcium binding in bone.

A varied and balanced diet usually covers these requirements.

Foods and Substances to Limit in Osteoporosis

This does not mean strict prohibitions, but rather moderate and mindful consumption.

• Caffeine

High intake may increase urinary calcium excretion. Limiting coffee, tea, and energy drinks can help protect bone health.

• Excess Phosphorus

Found mainly in soft drinks such as cola and in ultra-processed foods. Excess phosphorus disrupts the calcium–phosphorus balance and negatively affects bone density.

• Alcohol and Tobacco

Both interfere with new bone formation and increase the risk of fractures. Reducing or eliminating them is a key preventive measure.

• Phytates and Oxalates

Present in whole grains, cocoa, coffee, and some leafy green vegetables. It is not necessary to eliminate them, but it is advisable to combine them appropriately and ensure they do not displace calcium-rich foods.

Nutrition and Hormones: A Key Relationship

The loss of estrogen during menopause and testosterone in older men accelerates bone loss. For this reason, osteoporosis is more common in postmenopausal women and in men over the age of 65.

Proper nutrition, together with exercise and medical monitoring, can significantly slow this process.

Conclusion

Taking care of bone health does not depend on a single food, but on an overall lifestyle. A nutrient-rich diet, regular physical activity, and reducing harmful habits are the best tools to prevent osteoporosis and improve quality of life in the long term.

Not everything is about the glycemic index, and you don’t need to “eat unlimited protein.”

If you want to lose body fat, you have probably heard that you should avoid foods with a high glycemic index and significantly increase your protein intake. But what truly matters? Does the glycemic index influence weight loss as much as we think? And how much protein do you actually need? Below, we clarify both concepts based on scientific evidence and practical application.

Adriana Martín Peral – Neolife Nutrition Unit

What Is the Glycemic Index?

The glycemic index (GI) measures how quickly a carbohydrate-containing food raises blood glucose levels compared with pure glucose.

• High GI → rapid rise in blood glucose
• Low GI → slower rise

However, there is a limitation: the glycemic index is measured under isolated conditions, with the food consumed alone and in standardized quantities. In real life, we eat combinations of foods. For this reason, a more practical concept is glycemic load, which takes into account both the quality and the quantity of carbohydrates.

Does the Glycemic Index Matter for Weight Loss?

Evidence shows that:

• Low-GI diets may improve glycemic control.
• They can be particularly beneficial in individuals with insulin resistance.
• However, when calories and protein intake are controlled, GI alone does not determine fat loss.

The factors that most strongly influence weight loss are:

• Sustained caloric deficit
• Adequate protein intake
• Long-term adherence

A high-GI food does not “cause weight gain” by itself. The overall dietary context is what truly makes the difference.

Protein: The Key Player in Fat Loss

If there is one macronutrient that becomes especially important when aiming to lose fat without losing muscle mass, it is protein. Why?

• It increases satiety.
• It reduces the loss of muscle mass during a caloric deficit.
• It has a higher thermic effect (the body expends more energy digesting it).

This leads to an important question:

How Much Protein Is Actually Needed for Weight Loss?

The standard recommendation for the general population is 0.8 g/kg/day.

However, for fat loss and preservation of muscle mass, current evidence suggests an intake of 1.6–2.2 g/kg of body weight per day. That said, before increasing protein intake, it is important to ensure that there is no medical condition requiring a different nutritional approach. Protein intake should always be individualized and supervised by a healthcare professional.

Practical example:

A person weighing 70 kg who wants to lose fat should consume between 112 and 154 g of protein per day. This does not mean “eating unlimited protein.” Beyond this range, the benefits do not increase significantly.

What You Should Really Focus On

Instead of becoming overly concerned with the glycemic index:

• Ensure sufficient protein intake at each meal.
• Combine carbohydrates with fiber, fats, and protein.
• Prioritize minimally processed foods.
• Evaluate your long-term adherence rather than focusing exclusively on GI.

Improving your daily protein distribution will have a much greater impact on body composition than focusing solely on the glycemic index.

Conclusion

The glycemic index can be a useful tool in certain contexts, particularly in individuals with metabolic disturbances, but it is not the decisive factor when it comes to fat loss. What truly makes a difference is maintaining a sustainable caloric deficit, ensuring adequate protein intake, and building a dietary pattern that can be maintained over time.

Within this framework, protein plays a key role because it helps preserve muscle mass, improves satiety, and facilitates adherence to the nutritional plan. However, more is not always better, and recommendations should be adjusted according to each individual’s characteristics and health status.

Ultimately, losing weight does not depend on demonizing foods based on their glycemic index or consuming unlimited protein, but rather on applying strategy, scientific evidence, and long-term consistency.

The menopausal transition promotes changes in body composition. We analyze the hormonal factors involved and the most effective nutritional strategies.

During menopause, many women experience weight gain, particularly in the abdominal area. Although this is often attributed exclusively to “hormones,” the phenomenon is more complex. The decline in estrogen levels, changes in muscle mass, and metabolic adaptations all play a significant role. We review what actually happens and how to intervene effectively.

Adriana Martín Peral – Neolife Nutrition Unit

Hormonal Changes in Menopause: What Really Happens?

Menopause is characterized by a progressive decline in estrogen levels, particularly estradiol. This hormonal shift impacts:

• Redistribution of body fat toward a more android (abdominal) pattern.
• Decreased basal energy expenditure.
• Increased insulin resistance.
• Higher cardiometabolic risk.

Estrogens play a protective role at the metabolic level. Their decline favors greater accumulation of visceral fat, which is metabolically active and associated with inflammation.

Is It Only a Hormonal Issue?

Not exclusively. In addition to hormonal changes, other factors are involved:

• Loss of Muscle Mass (Sarcopenia)

From the ages of 40–50 onward, there is a progressive decline in muscle mass if no strength stimulus is present. Since muscle is metabolically active tissue, its reduction decreases daily energy expenditure.

• Decreased Total Energy Expenditure

Lower levels of spontaneous physical activity, changes in sleep patterns, and increased stress contribute to a sustained positive energy balance.

• Changes in Appetite and Satiety

Some women report increased cravings for energy-dense foods, possibly related to hormonal fluctuations and sleep disturbances.

Evidence-Based Nutritional Strategies

• Prioritize Adequate Protein Intake: A sufficient protein intake (approximately 1.2–1.6 g/kg/day depending on individual profile) helps to:
  • Preserve muscle mass.
  • Improve satiety.
  • Support glycemic control.

Distributing protein evenly throughout the day optimizes muscle protein synthesis.

• Strength Training + Nutrition: Resistance training is key to counteracting age- and menopause-related muscle loss. When combined with adequate protein intake, it improves body composition beyond what is reflected on the scale.
• Control Energy Density: Reduce ultra-processed foods and prioritize:
  • Vegetables
  • Whole fruit
  • Legumes
  • Healthy fats (extra virgin olive oil, nuts)
  • Lean protein sources

This approach supports satiety while lowering overall caloric load.

• Fiber and Metabolic Health: A high fiber intake (25–35 g/day) improves:
  • Insulin sensitivity
  • Lipid profile
  • Gut health

The gut microbiota also appears to play a relevant role in weight regulation during this stage.

Sleep and Stress

Sleep deprivation is associated with greater insulin resistance and increased appetite. Therefore, intervention should be comprehensive and lifestyle-oriented.

What Does NOT Work

• Extremely restrictive diets maintained over time.
• Complete elimination of food groups without clinical indication.
• Focusing exclusively on weight without assessing body composition.

During menopause, the goal should be to improve body composition and metabolic health—not simply reduce body weight.

Conclusion

Weight gain during menopause is not inevitable, but it does require a different approach. The combination of appropriate nutrition, strength training, and a comprehensive lifestyle strategy can improve body composition and reduce cardiometabolic risk during this stage of life.

Pulse wave velocity (PWV) is now the most accurate tool for the early detection of arterial aging and for understanding when hypertension truly begins—even when office blood pressure values are still within the normal range.

Added to this is the value of the renin/aldosterone ratio, which allows us to identify the underlying mechanism driving blood pressure elevation in each individual and to personalize management with unprecedented precision. This is what hypertension looks like in 2026: true anticipation and treatment tailored to each patient’s physiology.

Dr. Carlos Martí – Neolife Medical Team

For years, hypertension was understood as a number: above 140/90 mmHg meant “disease”; below that threshold, “everything was fine.”

Today we know this approach is insufficient. The most recent evidence points to something more profound: elevated blood pressure is the late consequence of accelerated arterial aging—now recognized as vascular aging—which can be detected long before the blood pressure cuff shows abnormal values.

What truly matters is no longer just measuring blood pressure, but understanding what is happening inside the arteries during that silent phase that determines future risk, even when everything appears normal. This represents one of the most important evolutions of recent years: hypertension is no longer seen solely as a diagnosis, but as an opportunity for early detection. A paradigm shift that reshapes how we assess cardiovascular risk and opens the door to earlier, more precise intervention with a real capacity for long-term prevention.

Over the past decade, we have learned that:

• Vascular damage begins 5–10 years before blood pressure readings become elevated.
• Arterial stiffness predicts real cardiovascular risk more accurately than brachial blood pressure.
• Many individuals with “normal–high” blood pressure already show signs of arterial aging.

For this reason, the latest updates prioritize the assessment of vascular physiology rather than interpreting numbers alone.

Arterial stiffness: the first “surname” of hypertension

One of the parameters that has gained the most relevance in recent years is pulse wave velocity (PWV), an essential marker of arterial stiffness. Understanding it is simple if we imagine our arteries as household pipes: when they are new, flexible, and well maintained, they absorb pressure and allow smooth flow. Over time, as they become stiffer, each pressure wave travels faster and with greater force.

PWV measures exactly how fast the pressure wave travels along the aorta.

When this wave travels too quickly, the artery has lost elasticity. And this can occur years before blood pressure rises. In other words, a person may have “normal blood pressure” and yet already display the first surname of future hypertension: increased arterial stiffness, indicating premature vascular aging.

SphygmoCor: measuring what very few can

Assessing arterial stiffness cannot be done with a conventional blood pressure monitor. At Neolife, we use SphygmoCor, the international reference technology used in advanced cardiovascular research.

This highly validated system allows us to:

• Accurately measure PWV.
• Calculate central blood pressure, which is the pressure that truly loads the heart and brain.
• Determine whether a patient’s arterial stiffness is appropriate for their age or reflects accelerated vascular aging.

This technology, although widely validated, is still largely limited to centers with an advanced approach to vascular assessment. Its true value lies in its ability to detect alterations during the silent phase, when intervention is still both effective and highly personalized.

This is the foundation of true prevention—not merely reactive care.

RAAS and the renin/aldosterone ratio: the second surname of hypertension

In recent years—and particularly in the most recent updates—the renin/aldosterone ratio has gained greater importance, as it allows us to go beyond blood pressure values and understand the internal mechanism driving blood pressure elevation in each individual.

The RAAS (renin–angiotensin–aldosterone system) is the body’s mechanism for regulating blood pressure, salt balance, and fluid volume. It functions as an internal blood pressure thermostat: when the body perceives insufficient pressure or volume, it activates the system to raise it; when there is excess, it suppresses it.

• Renin is the initial signal, released when the body detects low pressure or volume.
• Renin triggers the formation of angiotensin, which constricts arteries and rapidly increases blood pressure.
• Angiotensin then stimulates the release of aldosterone, a hormone that promotes sodium and water retention, increasing circulating volume and sustaining elevated blood pressure.

By analyzing the renin/aldosterone ratio, we can identify which part of the system is altered—essentially determining the physiological mechanism pushing blood pressure upward in that specific individual. This is key to personalizing treatment and identifying the “second surname” of hypertension: whether there is excessive system activation, aldosterone predominance, or abnormally low renin levels.

This approach allows us to move away from the uniform “one-size-fits-all” strategy. While some profiles clearly benefit from ACE inhibitors or angiotensin II receptor blockers (ARBs), others respond better to calcium channel blockers, beta-blockers, aldosterone antagonists, or even targeted supplementation and lifestyle optimization strategies.

Lifestyle in 2026: interventions that truly rejuvenate the vasculature

New guidelines emphasize something we know well at Neolife: not all lifestyle recommendations impact arterial health in the same way. Certain interventions directly improve arterial stiffness and central blood pressure.

Resistance training combined with high-intensity intervals improves aortic elasticity more effectively than moderate exercise alone. Reducing visceral fat decreases hemodynamic load and improves central pressure.
Achieving deep, stable sleep—particularly restoring the normal “dipper” pattern—acts as a powerful nocturnal cardiovascular protector.
The dipper pattern refers to the natural nighttime reduction in blood pressure, typically around 10–20%. When this decline does not occur, cardiovascular risk increases significantly. It is assessed through 24-hour ambulatory blood pressure monitoring (ABPM), which tracks blood pressure behavior during sleep.

Importantly, these changes are not applied intuitively, but through a personalized approach: identifying the dominant mechanism in each individual and directing lifestyle interventions toward that specific target.

Because hypertension is not prevented with generic advice, but by optimizing arterial physiology through precise and measurable interventions.

The true antiaging approach: acting before disease appears

Traditional medicine diagnoses hypertension once blood pressure crosses a defined threshold. Longevity medicine prefers to intervene when physiology begins to deviate—before pathological numbers appear—helping the body return to its natural, physiological balance.

If a patient already shows a first surname (increased arterial stiffness), a second surname (altered RAAS), or even rising central blood pressure, we are facing an early but still manageable process. This is the window of opportunity to get ahead of arterial aging and prevent long-term complications.

That is the Neolife approach: anticipate, identify early changes, and act with precision to keep arterial health on its youngest possible trajectory.

Ultra-processed foods are not designed merely to nourish us: they are carefully engineered to make us want to keep eating. It is no coincidence that opening a bag of potato chips or a packet of cookies almost always ends with “just a little more,” until, before we realize it, the package is empty.

These products (snacks, sweets, fast food…) may seem harmless, but behind their intense flavor, perfect texture, and irresistible aroma lie hours of testing, formulas, and fine-tuning aimed at stimulating our senses and activating the brain’s reward system. What exactly do these foods contain that makes them so hard to stop eating? Why can a single bite turn into a chain of cravings? The answer lies in their design: a precise combination of ingredients, textures, and sensory stimuli that subtly encourages us to keep eating.

Adriana Martín Peral – Neolife Nutrition Unit

What Are Ultra-Processed Foods?

Ultra-processed foods are products that undergo multiple industrial transformations and contain a long list of ingredients you would not normally find in a home kitchen. Beyond basic components such as wheat, corn, or milk, they often include added sugars, low-quality fats, flavor enhancers, additives, and texturizers, all designed to improve taste, appearance, and shelf life. The goal of these processes is not only to extend the product’s durability but also to create a perfect texture, an intense flavor, and a pleasurable eating experience, all while keeping production costs low. This is why, although they may appear to be simple snacks or ready-to-eat meals, each bite involves food engineering designed to capture our attention and keep us eating for longer.

How Ultra-Processed Foods Create Cravings

It is no coincidence that it is so difficult to stop after opening a bag of chips or a packet of cookies. Ultra-processed foods are designed to activate the brain’s reward system, releasing dopamine and making each bite more appealing than the last. This is achieved through what experts call the “irresistible triad”: sugar, fat, and salt. The precise combination of these three elements is carefully calibrated to maximize pleasure without becoming overwhelming, stimulating the release of dopamine, the neurotransmitter associated with pleasure and motivation.

Added to this is the concept of the “bliss point,” which describes the exact level of sugar, fat, or salt that produces the greatest satisfaction. Companies conduct extensive sensory testing to find the perfect proportion, ensuring that each bite is highly pleasurable and difficult to abandon.

Moreover, the texture and aroma of these foods are engineered to reinforce pleasure. The perfect crunch of potato chips, the melt-in-your-mouth smoothness of chocolate, or the softness of certain industrial breads send signals of freshness and flavor to the brain, increasing the compulsion to eat more. Even the low satiety of many ultra-processed foods (due to their low fiber or protein content) contributes to the brain continuing to ask for “just a little more,” even when the stomach is already full.

Ultra-processed foods do not rely solely on sugar, fat, and salt. Aromas and flavor enhancers also play a role in making each bite more irresistible. Ingredients such as monosodium glutamate (MSG), artificial flavorings, and industrial aromas intensify taste so that the brain perceives the food as more flavorful than it truly is. These additives provide no nutritional value but deceive our senses, generating a sense of pleasure that encourages continued consumption. It is a small chemical and sensory trick that, combined with other factors, makes stopping extremely difficult.

Another key factor is that many ultra-processed foods generate low satiety, meaning we do not feel sufficiently full despite having consumed many calories. This is because they tend to be calorie-dense but poor in fiber and protein—nutrients that help regulate appetite. As a result, the brain continues to send signals of hunger or craving even after sufficient energy intake. This combination of low satiety and high sensory reward turns these foods into an almost automatic cycle of eating more, again and again.

Marketing and Environment: Induced Cravings

It is not only ingredients and sensory engineering that make ultra-processed foods hard to resist; marketing and environment also play a key role in generating cravings and impulsive purchases. Bright packaging colors, eye-catching designs, and noisy wrappers are carefully designed to capture attention and associate the product with fun or pleasure.

In addition, many of these products are sold in small portions that seem harmless, leading us to underestimate how much we are consuming. This psychological design makes opening a package far more tempting and easy to eat “without guilt,” even though you may end up consuming more than planned.

Targeted advertising further reinforces these habits—not only in children, but also in adults. Commercials, social media, and promotions associate these foods with happy moments, rewards, or indulgence, creating emotional connections that go beyond simple hunger.

Finally, strategic placement in stores and supermarkets increases impulsive consumption. Positioning snacks at eye level, near checkout counters, or in main aisles makes them almost impossible to ignore. Even if you go shopping for a single ingredient to cook, constant exposure to these products activates the desire to buy and consume them immediately.

Together, these marketing and environmental factors do not merely sell the product—they manipulate our cravings, reinforcing the habits that ultra-processed foods have already begun to create through taste and texture.

Practical Example: Why Potato Chips Crunch the Way They Do

The crunch of potato chips does not happen by chance; it is the result of careful sensory engineering. Brands specifically adjust sound and texture so that each bite is highly pleasurable and encourages continued eating.

1. The crunching sound stimulates the brain

The characteristic “crack” activates brain areas associated with pleasure and the perception of freshness. Noisy foods are perceived as fresher, newer, and more desirable, and companies calibrate the hardness and shape of the chips to make the sound as “perfect” as possible. Studies have shown that when the crunch is amplified, people rate chips as tastier, even if they are exactly the same product.

2. Extremely low moisture content

Potato chips are fried until they contain only about 1–2% moisture. This extreme dryness makes their structure fragile, breaking into small fractures when bitten and producing a highly satisfying crunch. With more moisture, they would become chewy or soggy and lose this effect.

3. Porous structure and trapped air

During frying, the water inside the potato rapidly turns into steam, creating small internal bubbles. This microcavity-filled structure causes the chip to break into many particles at once when bitten, producing a more complex and pleasant crunch.

4. Fat and salt coating: the winning combination

The fat coating lubricates the mouth and enhances flavor, while salt intensifies taste and increases salivation. Together, fat and salt make the crunch more pronounced and the eating experience even more rewarding.

5. Crunch equals instant reward

The crunch reaches the ears milliseconds before the mouth perceives it, and the brain interprets it as “delicious.” This signal triggers a small dopamine release, reinforcing the habit of continuing to eat. That is why, even when we are full, sound and texture can push us to eat more than we need.

Conclusion

Ultra-processed foods are not simply foods: they are carefully designed products created to generate cravings. Their combination of flavor, texture, aroma, marketing, and low satiety activates brain reward circuits, creates automatic habits, and makes it difficult to stop—even when the body has already received enough energy. Understanding how these mechanisms work allows us to make more conscious choices and prioritize real foods most of the time, reducing the influence of strategies designed to keep us eating more.

You may not know that in Spain between one third and nearly half of adults have hypertension. This means that between 1 and 2 out of every 4 people suffer from high blood pressure, even though they may not be aware of it.

You may also be unaware—or not fully conscious—that, much like diabetes mellitus, arterial hypertension (HTN) is one of the main “silent killers” affecting our society. It often causes no symptoms, yet gradually damages our blood vessels and internal organs, increasing the risk of serious and potentially life-threatening complications. Every millimeter of mercury (the unit used to measure blood pressure) that is controlled represents time gained and health preserved. Would you like to understand why this is so?

Risk factors

In part 1 of this article, we discussed what hypertension is and its consequences. In this second part, we will review risk factors and pharmacological treatment.

There are several risk factors that contribute to the development of arterial hypertension. Some cannot be changed, but others are within our control.

1. NON-MODIFIABLE RISK FACTORS

• Age

Blood pressure tends to increase with age because blood vessels gradually lose elasticity, hormonal changes affect fluid and salt balance, and the cumulative effects of unhealthy habits build up over time. While approximately 5–10% of women aged 20–44 have hypertension, prevalence rises dramatically to 85% in women aged 75 or older (comparable figures for men are 10–15% and 80%, respectively).

• Race

High blood pressure affects people of all races, but African Americans have a significantly higher risk of developing hypertension. African American women, in particular, have higher rates than men from other racial groups. For this reason, African Americans should begin monitoring their blood pressure and adopting healthy habits from a young age. Other racial groups have similar risk levels, although Asian women tend to have a lower risk. Despite this, many Hispanic and Asian individuals with hypertension are unaware of their condition and remain untreated, highlighting the importance of blood pressure monitoring for everyone.

• Family history and genetics

Having parents or close relatives with hypertension increases your risk, as approximately 50% of blood pressure variability is hereditary. More than 800 genetic variants influence blood pressure; although each has a small effect individually, their cumulative impact can accelerate the development of hypertension with age. Therefore, genetic predisposition requires regular monitoring and awareness of family history. Nevertheless, healthy lifestyle habits can offset a large part of this risk.

2. MODIFIABLE RISK FACTORS

Lifestyle modifications often provide effective, non-pharmacological ways to control or reduce blood pressure, sometimes with results comparable to medication. A large proportion of hypertension cases are due to an unhealthy diet (and associated obesity), lack of exercise, excessive alcohol consumption, or a combination of these factors.

• Obesity

One of the most effective lifestyle interventions for blood pressure control is weight loss. Excess body weight overloads the heart and promotes insulin resistance, both of which contribute to elevated blood pressure. Research shows a direct and consistent relationship between body mass index (BMI) and hypertension. Large studies suggest that obesity may account for 40–78% of hypertension cases.

Even modest weight loss can produce significant blood pressure reductions. A 2003 meta-analysis of 25 randomized clinical trials in overweight and obese adults found that for every kilogram of weight lost, systolic blood pressure decreased by approximately 1 mmHg and diastolic pressure by 0.92 mmHg.

Weight loss can be achieved through caloric restriction, intermittent fasting, or dietary changes, and the best approach depends on what is most sustainable for each individual.

• Dietary salt (sodium)

The relationship between dietary sodium, hypertension risk, and overall health is complex. Some individuals and groups are more sensitive to the blood-pressure-raising effects of salt. These include African Americans, older adults, people with diabetes, chronic kidney disease, or pre-existing hypertension. For these groups, sodium intake should be reduced, ideally to 2,000 mg per day or less.
Although organizations such as the American Heart Association recommend even lower limits (1,500 mg/day), it is important to note that excessively low sodium intake can also cause problems. Studies have shown that very low sodium consumption may be associated with headaches, mental status changes, lethargy, cramps, nausea, dehydration, and excessively low blood pressure, increasing the risk of falls and injuries in older adults. Therefore, moderate sodium reduction is advised for low-risk individuals, with more aggressive reduction reserved for those who are salt-sensitive.

In addition to reducing sodium, increasing potassium intake—a mineral essential for muscle function, kidney health, and blood vessel relaxation—can help lower blood pressure. In hypertensive adults, potassium intake can reduce systolic pressure by 3–6 mmHg and diastolic pressure by 1–4 mmHg. The sodium-to-potassium ratio appears to be more important than absolute intake levels. Foods rich in potassium, such as bananas, potatoes, and legumes, are especially beneficial for individuals with high salt intake.

• Exercise and blood pressure

Aerobic exercise is highly effective. A meta-analysis of clinical trials lasting at least four weeks found that aerobic training can reduce systolic blood pressure by up to 8 mmHg and diastolic pressure by at least 5 mmHg. The optimal dose is 90–150 minutes per week at 65–75% of maximum heart rate (the so-called “Zone 2”). At Neolife, we recommend at least three hours per week.

• Dynamic resistance training

Strength training may temporarily raise blood pressure during exercise, but in the long term it reduces systolic pressure by about 2 mmHg and diastolic pressure by 3 mmHg, when performed for 90–150 minutes per week using weights ranging from 50–100% of one-repetition maximum.

• Isometric resistance training (no weights)

This type of exercise has shown even greater reductions in systolic blood pressure—around 6 mmHg—and 3 mmHg in diastolic pressure, despite its seemingly low intensity.

• Alcohol

Current evidence shows that alcohol raises blood pressure in a dose-dependent manner. Genetic studies using Mendelian randomization confirm that even small amounts increase risk: each additional daily drink raises hypertension risk by 30%, and in heavy drinkers this risk can increase by up to 160%. There is no “safe” level of alcohol consumption for blood pressure. The good news is that reducing or stopping alcohol intake significantly lowers risk and improves cardiovascular health, even in former heavy drinkers.

3. OTHER FACTORS

• Sleep

Poor sleep—whether due to insufficient or excessive duration, or disorders such as insomnia, snoring, or sleep apnea—is associated with a higher risk of hypertension. Evidence shows a U-shaped relationship, with increased risk below 7 hours and above 9 hours of sleep. Optimizing sleep quality is essential; up to half of hypertension cases could potentially be managed without medication through lifestyle changes alone.

• Stress

Chronic stress is a major contributor to hypertension. Stress hormones such as cortisol increase heart rate and constrict blood vessels. Unhealthy coping mechanisms—overeating, smoking, or alcohol use—can further worsen blood pressure. Mindfulness, meditation, deep breathing, and physical activity are recommended strategies. Relaxation techniques and biofeedback have shown modest blood pressure reductions in some patients.

• Caffeine

Caffeine can temporarily raise blood pressure, particularly in people who do not consume it regularly. However, habitual consumption does not appear to cause sustained hypertension or increase long-term risk.

• Insulin resistance

Insulin resistance and type 2 diabetes significantly impact blood pressure by reducing nitric oxide bioavailability, impairing vasodilation and increasing vascular resistance.

Pharmacological treatment

As discussed, blood pressure control is a cornerstone in reducing cardiovascular disease, stroke, and kidney damage. Lifestyle modifications are the first-line approach, but when insufficient, pharmacological treatment becomes necessary.

Antihypertensive therapy must always be prescribed by a physician, who will select the most appropriate option based on individual characteristics and comorbidities.

There are four main first-line drug classes:

1. Thiazide diuretics
2. Calcium channel blockers
3. Angiotensin-converting enzyme inhibitors (ACE inhibitors)
4. Angiotensin II receptor blockers (ARBs)

All typically reduce systolic blood pressure by 12–15 mmHg and diastolic pressure by 9–11 mmHg.

ACE inhibitors, for example, can reduce blood pressure by up to 12.5/9.5 mmHg. It is recommended to initiate treatment at half of the maximum dose to minimize the risk of adverse effects. ARBs (angiotensin II receptor blockers) offer similar efficacy but with fewer side effects. In many cases, they are even considered superior, although ACE inhibitors tend to be less expensive because they have been on the market longer.

When ACE inhibitors cause cough—a common side effect—patients can be easily switched to an ARB. Thiazide diuretics and calcium channel blockers are also effective, achieving reductions of up to 15/10 mmHg, but they are more frequently associated with adverse effects. For this reason, they are often used as adjunctive therapy, once treatment with ACE inhibitors or ARBs has been optimized. As always, treatment decisions must be individualized.

This raises an important question: are there factors that determine which medication is best for a particular individual? The answer is yes. The optimal choice of antihypertensive therapy is patient-specific and depends on the presence of comorbid conditions and tolerance to potential side effects. For example, most calcium channel blockers are contraindicated in heart failure with reduced ejection fraction, and thiazide diuretics are generally considered less appropriate for patients with diabetes or prediabetes, as they may worsen metabolic parameters. ACE inhibitors and ARBs are contraindicated during pregnancy, although they are generally associated with fewer adverse effects than calcium channel blockers and thiazide diuretics.

Summary

It is important to emphasize that while medications are often more effective than any single lifestyle intervention, the combined effect of multiple lifestyle improvements can match the benefits of pharmacological therapy.

At Neolife, we believe that blood pressure management is one of the most important pillars of longevity. It may not seem as glamorous as the latest anti-aging treatments, but it remains one of the most effective and well-established approaches in preventive medicine for reducing morbidity and mortality.

La entrada “Silent Killer”: Understanding What Arterial Hypertension Is and Its Consequences (Part 2) se publicó primero en Neolife.

Understand the biological and emotional keys behind your food choices and improve your relationship with food

We often believe that eating until we feel “full” is synonymous with having eaten well. However, true nourishment depends not only on how much we eat, but also on how we feel afterward. In this article, we explain the differences between satiety and satisfaction—two concepts that, although similar, have very different impacts on our health and well-being.

Arantxa Jiménez – Neolife Nutrition Unit

What Is Satiety?

Satiety is a physiological response of the body that signals that the stomach is full and that, at least temporarily, no more food is needed. It is mainly regulated by hormones such as leptin, insulin, and cholecystokinin, which send signals to the brain to reduce appetite after food intake.

In simple terms, being satiated means no longer feeling physical hunger. This state can be achieved by eating large quantities of food, even if those foods are not particularly nutritious or enjoyable. For example, a meal high in refined carbohydrates may fill you up quickly, but it does not necessarily nourish you or provide satisfaction.

What Is Dietary Satisfaction?

Satisfaction, on the other hand, is a more subjective and emotional process. It involves feeling that what you ate was enjoyable, sufficient, and aligned with your real needs and desires. It relates to how you experience food—its flavor, texture, temperature, and even the environment in which you eat.

Feeling satisfied means that food has fulfilled a purpose beyond simply relieving hunger: it has been a pleasant and nourishing experience. This type of eating is often associated with a healthier relationship with food and can help prevent binge eating or subsequent emotional eating.

Key Differences Between Satiety and Satisfaction

Why Does This Difference Matter?

Understanding this distinction is essential for achieving intuitive and mindful eating. Eating solely to reach satiety can lead to automatic or restrictive eating patterns, while also seeking satisfaction allows for more balanced, sustainable, and pleasurable food choices.

Moreover, when meals are satisfying, individuals are more likely to respect internal hunger and fullness cues, which can help prevent emotional eating, constant snacking, or late-night binge episodes.

Tips for Achieving Both Satiety and Satisfaction When Eating

1. Include all three macronutrients (carbohydrates, healthy fats, and protein) in your meals to promote sustained satiety.
2. Listen to your body and learn to distinguish between true hunger and emotional or habitual eating.
3. Make your meals a sensory experience: pay attention to flavor, aroma, texture, and your surroundings.
4. Eat without guilt: food also serves emotional and social purposes.
5. Plan meals you truly enjoy—eating well does not mean giving up pleasure.
