Serum leptin levels are significantly higher in women than in men for any given measure of obesity (BMI or percent body fat) above 25% body fat, indicating a state of relative leptin resistance in women.
If you are a woman, your body naturally produces more leptin than a man of the same weight or body fat percentage. This higher baseline may contribute to a state of 'leptin resistance,' making it physiologically harder to sustain diet-induced weight loss compared to men. This is a biological difference, not a failure of willpower.
However, for any given measure of obesity, leptin levels are higher in women than in men, consistent with a state of relative leptin resistance.
Why this rating
Large sample size (n=116), wide range of BMI (17-54), and rigorous metabolic ward characterization.

- In men, but not women, serum leptin levels are negatively correlated with insulin sensitivity (maximal glucose uptake) and positively correlated with blood pressure and waist-to-hip ratio.Good
- Leptin regulates body weight in humans predominantly by affecting eating behavior (satiety) rather than by increasing energy expenditure (calorigenesis).Moderate

- 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
