Dietary Substrate Timing

Meaning

Dietary Substrate Timing is a structured nutritional strategy that involves the deliberate consumption of specific macronutrients—carbohydrates, proteins, and fats—at predetermined intervals relative to physiological events, such as exercise or the circadian rhythm. The primary objective is to synchronize nutrient availability with the body’s fluctuating hormonal and metabolic demands to maximize specific outcomes like muscle protein synthesis, glycogen repletion, or fat oxidation. This clinical application is a sophisticated refinement of nutritional planning, moving beyond mere caloric counting to leverage the chronobiological impact of food.
