Leptin Sensitivity
Better satiety hormone response for improved appetite control.
TL;DR
Leptin resistance is a consequence of excess adiposity, poor sleep and inflammation, not a condition treated directly. Fat loss, sleep and protein intake restore signalling; no supplement reliably does.
Why It Matters
Leptin resistance sustains excess hunger and reduced energy expenditure after weight gain and contributes to weight regain after dieting. Congenital leptin deficiency is vanishingly rare and unrelated to common obesity.
How to Measure
Biomarkers
Optimization Protocol
Lose excess body fat gradually, since leptin signalling improves as adiposity falls. Sleep seven to nine hours, because short sleep lowers leptin and raises ghrelin. Eat 1.2-1.6 g/kg protein and prioritise fibre and whole foods over ultra-processed items. Avoid aggressive crash dieting, which suppresses leptin and drives regain.
Supporting Supplements
Omega-3 Fatty Acids
Omega-3 reduces the inflammation implicated in hypothalamic leptin resistance, though appetite effects are inconsistent.
Vitamin D
Vitamin D is associated with leptin levels observationally but supplementation has not shown a clear effect.
