How to Be 40 with the Biological Age of a 25-Year-Old?

From the age of 20, we all start aging, but the pace of aging varies for everyone. And the good news is — you can control it! Traditionally, "youth" and "old age" are associated with a person’s age, but there’s no clear line between the two

How to have the biological age of a 25-year-old at 40?

There isn’t a specific chronological moment when your heart will make its last beat, signaling the depletion of its resources. The number of years since birth is not a true indicator of health, which is why we refer to biological and chronological ages, and often, they do not match. So, what is aging, and how can we delay its onset?

Aging is primarily the gradual and progressive decline in hormone production and function, an increased risk of chronic diseases, and shortened life expectancy. Numerous hormonal and metabolic changes contribute to the development of major age-related chronic diseases, as well as a decline in physiological functions. These include atherosclerosis, hypertension, hyperlipidemia, obesity, sarcopenia, dementia, osteoporosis, thrombosis, chronic inflammation, and weakened immune function.

One of the key signs of aging is the decline in cognitive functions (memory loss and reduced mental sharpness), which is linked to degenerative brain diseases, often triggered by metabolic issues.

Therefore, the primary goal in preserving youth is to maintain hormonal balance and a healthy metabolism, while proactively preventing changes that lead to chronic and age-related diseases. How can this be achieved? By following the Age Management strategy. The tools you use depend on your age. Let's break it down for those whose biological age roughly aligns with their chronological age.

Age 20+

In your 20s, maintaining health is fairly simple, mostly just avoiding harm. Hormone production is still naturally high, and as long as you don’t interfere with it, health care is largely about basic supplementation and preventive measures using common sense.

This includes avoiding:

• Sleep deprivation (which blocks growth hormone production, already declining rapidly),

• Relying on fast food deliveries, coffee instead of breakfast, and eating dinner at 9 p.m. (which spikes insulin, leading to metabolic issues),

• A sedentary lifestyle and alcohol (which lower testosterone levels, disrupt detoxification systems, and increase the risk of obesity),

• Smoking (which impairs reproductive function, damages blood vessels and lungs, and increases the risk of cancer).

  
  

When it comes to supplements, it’s about basics like Omega-3, Vitamin C, magnesium, and Vitamin D, as well as nutraceuticals tailored to specific needs (amino acids and fiber to balance the diet, or adaptogens to maintain high stress resilience, etc.).

Age 30+

After 30, natural hormone production starts to decline, so in addition to a healthy lifestyle, more supplements are needed (especially substrates for producing sex hormones), and BHRT (Bioidentical Hormone Replacement Therapy) may be required to optimize endocrine balance.

It’s important to understand that aging affects not only hormone secretion but also their biological availability (particularly sex hormones) and their impact on target organs (e.g., tissues' resistance to insulin, which can lead to insulin resistance and eventually diabetes). Your relationship with a healthy lifestyle should become more disciplined, and close cooperation with an age-management specialist, especially with regular check-ups, becomes essential.

Age 40+

After 40, hormonal support becomes a priority, and tools from the “age management pyramid” (including High-Tech and biotechnologies) take on greater importance. However, thinking you can forget about a healthy lifestyle is incorrect. In your 30s, age-management protocols can still compensate for some lapses in your lifestyle. But as you get older, neglecting to modify daily habits will reduce the effectiveness of BHRT. For example, in your 30s, you may not feel the consequences of skipping workouts, as your body still has residual resources and muscle mass. But closer to 50, the repercussions of neglecting your health will be much more significant.

It’s never too late to start, but the earlier you embrace and integrate Age Management principles into your life, the easier it will be to maintain your health and avoid many problems. Prevention is always better than cure, and it’s easier to preserve youth than to regain it!
