What is the Origin of Fat Burning Hormones?

The concept is rooted in classical endocrinology and metabolic physiology, which established the distinct roles of various hormones in nutrient partitioning and energy homeostasis. Early research identified the counter-regulatory nature of these hormones against insulin, particularly their function during periods of fasting or intense physical activity. The term is a functional, descriptive label for hormones with a net catabolic effect on adipose tissue.

What is the Mechanism of Fat Burning Hormones?

The mechanism involves these hormones binding to specific receptors on adipocytes, initiating a cascade that activates hormone-sensitive lipase (HSL), the enzyme responsible for hydrolyzing triglycerides into glycerol and free fatty acids. Thyroid hormones, specifically T3, increase the basal metabolic rate and mitochondrial uncoupling, enhancing thermogenesis. Growth Hormone further contributes by promoting lipolysis and decreasing glucose utilization, effectively sparing glucose and encouraging fat oxidation.

Fat Burning Hormones

Meaning

Fat Burning Hormones are a collective group of endocrine signaling molecules that regulate lipolysis, thermogenesis, and the utilization of stored adipose tissue as a primary fuel source. Key hormones in this category include glucagon, epinephrine, norepinephrine, thyroid hormones, and to some extent, Growth Hormone and testosterone. These hormones operate as critical metabolic regulators, facilitating the mobilization of fatty acids from adipocytes into the bloodstream for energy use.
