If it tends to run high

  • High-Protein Breakfast

    Protein in the morning helps restore your hypothalamus sensitivity to leptin signals.

  • Three Meals Only

    Stop snacking. Three structured meals give leptin time to signal properly between meals.

If it tends to run low

  • Never Skip Breakfast

    Skipping meals drops leptin further. Start with a balanced meal within an hour of waking.

  • Prioritize Sleep

    One night of poor sleep drops leptin 15-20%. Aim for 7-9 hours consistently.
