Chrononutrition Principles

Meaning

Chrononutrition Principles constitute a set of dietary and lifestyle guidelines that emphasize when food is consumed in relation to the body’s intrinsic circadian rhythms, rather than solely focusing on what is eaten. This practice acknowledges the time-of-day dependence of metabolic processes, including nutrient absorption, hormone secretion, and energy expenditure. Aligning food intake with the body’s internal clock is proposed to optimize metabolic health and weight management.
