Leptin directly stimulates lipid oxidation and lipolysis in white adipose tissue (WAT) through sympathetic nervous system activation and direct receptor binding, independent of its central effects on food intake.
Leptin does directly tell fat cells to burn fat, but this happens mostly in the brain's control of appetite. The direct effect on fat cells requires very high hormone levels not seen in normal human physiology.
GoodSupportsMEDIUM confidence
Findings from in vivo studies in rodents, in which leptin was administered peripherally, or with adenovirus-induced hyperleptinemia, support the role of leptin on adipose tissue metabolism, increasing lipolysis and decreasing fat synthesis, independently of its effects on food intake [101–103].
Why this rating
Strong rodent data, but human relevance is qualified by the need for supraphysiological doses.

- Exogenous leptin therapy is effective in treating obesity and metabolic disorders only in individuals with congenital leptin deficiency or generalized lipodystrophy, but is ineffective for the majority of people with common obesity.Strong
- In human obesity, elevated circulating leptin levels do not result in weight loss or reduced adiposity due to central leptin resistance, primarily caused by impaired transport across the blood-brain barrier and downstream signaling defects.Good

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
- For patients with specific monogenic obesity syndromes (leptin deficiency, POMC/PCSK1/LEPR mutations), targeted pharmacotherapy (recombinant leptin or setmelanotide) is highly effective and should be prioritized, unlike in polygenic obesity.Strong
- Continued weekly administration of 2.4 mg subcutaneous semaglutide prevents weight regain and promotes further weight loss in adults with overweight or obesity, whereas switching to placebo results in significant weight regain.Strong
