Restriction calorique et longévité

Definition

Réduction modérée et contrôlée de l'apport calorique quotidien (généralement 20-40% en dessous des besoins) associée à l'allongement de la durée de vie dans les études scientifiques.

How it works

Moderate caloric restriction, typically 20-40% below needs, is one of the few scientifically proven interventions to increase lifespan in many species. It works by activating cellular repair pathways, improving insulin sensitivity, and reducing systemic inflammation. In humans, a moderate 15-25% reduction in energy intake has shown benefits without major malnutrition risk. This practice should be progressive and guided to maintain adequate nutritional balance.

Role

Activate cellular repair mechanisms and prolong healthy lifespan by optimizing energy metabolism.

Examples

• Reduce daily energy intake by 300-500kcal, 16:8 intermittent fasting, Mediterranean hypocaloric diet, reducing portion sizes without omitting food groups

Recommendations

Consult a healthcare professional before beginning prolonged caloric restriction. Ensure adequate intake of vitamins, minerals, and protein. Progressive and measured restriction is preferable to drastic reduction.

Key takeaway

Moderate and well-planned caloric restriction may add years of life by optimizing biological aging processes.
