The precise circadian and physiological schedule dictating when stored triglycerides within adipocytes are broken down and released into the bloodstream as free fatty acids for energy use. This process is critically influenced by the interplay of hormones like cortisol, insulin, and catecholamines throughout the 24-hour cycle. Understanding this timing is essential for optimizing metabolic health and body composition.
Origin
This term is a conceptual composite drawn from the established fields of endocrinology, chronobiology, and lipid metabolism. It merges the biological concept of “adipose mobilization” (lipolysis) with the time-dependent regulation studied in “circadian rhythm” research. The clinical utility lies in timing interventions like exercise or fasting to align with natural physiological windows.
Mechanism
The primary mechanism involves a shift in the ratio of lipolytic to anti-lipolytic hormonal signals acting on adipose tissue receptors. Elevated catecholamines and growth hormone, often peaking during periods of fasting or deep sleep, activate hormone-sensitive lipase to initiate triglyceride breakdown. Conversely, high insulin levels, typically post-prandial, strongly suppress this mobilization process, directing the body toward storage.
