Leptin–Ghrelin Interactions
Adipose Tissue, Adipokines and Appetite Regulation
Leptin–Ghrelin Interactions
Leptin and ghrelin provide different information about longer-term energy status and meal-related conditions.
Adipose tissue sends information
Adipose tissue contains adipocytes, vascular cells and immune populations with distinct secretory contributions. Depot, energy status and inflammation influence the resulting endocrine profile. A circulating association does not establish the producing cell or prove a causal metabolic effect.
Specific considerations
Their interactions occur within neural networks rather than a simple opposing blood ratio.
Appetite is integrated
Hunger and food intake reflect endocrine signals together with neural reward, meals, sleep and environment. Low energy availability can occur at different body sizes. No single adipokine concentration can independently determine an athlete's fueling requirements.
