Leptin is a hormone produced by fat tissue, in proportion to the amount of fat stored — it signals the brain about the body’s energy reserves and plays a central role in appetite regulation and metabolic rate.
Leptin production and signaling are influenced more by overall energy balance and sleep quality than by a specific nutrient precursor; adequate sleep is one of the most consistently studied factors in healthy leptin signaling in the research literature.
Leptin itself is not a standard prescribed therapy in this practice (a leptin analog, metreleptin, is FDA-approved for a specific rare condition unrelated to general weight management). Leptin is discussed here for its physiological relevance to metabolic health broadly.
