    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

    Body fat percentage
    Waist circumference
    Fasting leptin (research use)
    hs-CRP
    Sleep duration
    Protein intake

    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.
