Muscle loss isn't 'normal' with age: it's a biological warning sign of what is disappearing underneath the surface. Over time, many people notice thinner legs, more prominent knees, less firm contours. The mistake is to think it's just an aesthetic change. Actually, what's missing is muscle, and with it, essential functions to live well and longer.
This process is called ‘Sarcopenia’ and it's one of the most powerful indicators of biological fragility.
Muscle is not just strength or movement. It is a metabolic and endocrine organ that:
- Regulates glucose and insulin sensitivity
- Reduces chronic inflammation
- Produces protective signals for the brain and heart
- It hosts mitochondria, the energy factories of the body
- Holds balance, gait and the ability to react to falls
When muscle is lost, the risk of falls, fractures and loss of autonomy increases.
- It is associated with greater cognitive impairment and cardiovascular events, and an
increase early mortality. Not because the muscle is "strong", but because it keeps the organism functional.
Contrary to a commonly held belief Sarcopenia doesn't start at 70, in many cases it begins before 40 and progresses without obvious symptoms, especially with sedentary, low-protein diets and chronic diseases.
The good news: muscle can be recovered, even after years of inactivity, it responds when it receives the right stimulus.
Three fundamental pillars:
1. Proper nutrition
Prioritize complete, quality proteins, along with healthy fats and micronutrients: eggs, fish, legumes, nuts, seeds, olive oil, avocado, dairy according to tolerance.
2. Move with intention
A gym is not a must. Load bearing exercise eg Walking, climbing stairs, body-weight exercises. The key is progression, not perfection.
3. Nutritional support when indicated
Creatine, backed by scientific evidence even in older adults, can be a useful tool when properly directed, along with an anti-inflammatory diet.
In summary, Accelerated aging does not begin on the skin, it begins when the muscle that holds energy, stability and independence is lost.
Building and retaining muscle is not an aesthetic goal, it's a health and survival strategy.
