Ghrelin Regulation
Controlled hunger hormone levels for reduced cravings.
TL;DR
Ghrelin rises with weight loss and sleep deprivation, which is why hunger increases when you diet or sleep badly. Protein, fibre and adequate sleep blunt it far more reliably than any supplement.
Why It Matters
Ghrelin surges after weight loss and remains elevated for a year or more, which is a major physiological driver of weight regain. Short sleep raises ghrelin and lowers leptin, increasing appetite for energy-dense food.
How to Measure
Biomarkers
Optimization Protocol
Eat 25-40 g of protein per meal, get 25-35 g of fibre daily, and protect seven to nine hours of sleep. Avoid aggressive crash deficits, which drive the largest ghrelin rebound. Resistance training preserves lean mass and improves appetite regulation. No supplement meaningfully suppresses ghrelin.
Supporting Supplements
Whey Protein
Protein is the most reliable dietary lever on hunger hormones, and whey is a convenient way to hit the dose.
Magnesium
No direct evidence that magnesium alters ghrelin; any appetite benefit is indirect via sleep.
