The Four Key Hormones:

1. Leptin (Satiety Hormone)

Natural Boosters:

  • Sleep: 7-9 hours increases leptin sensitivity by 30%
  • Omega-3s: 2,000mg EPA/DHA daily reduces leptin resistance
  • Strength Training: Increases leptin receptors in hypothalamus

Data: University of Chicago found sleep restriction (4 hours) decreases leptin by 18% and increases hunger by 24%.

2. Ghrelin (Hunger Hormone)

Natural Suppressors:

  •  Protein: 30g per meal reduces ghrelin more than carbs/fat
  • Fiber: 14g psyllium husk before meals decreases ghrelin by 22%
  • Consistent Meal Timing: Irregular eating increases ghrelin spikes by 40%

Study: American Journal of Clinical Nutrition shows high-protein breakfast reduces ghrelin more effectively than high-carb breakfast.

3. Insulin (Storage Hormone)

Natural Regulators:

  • Vinegar: 2 tbsp before meals improves insulin sensitivity by 34%
  • Cinnamon: 1g daily reduces fasting insulin by 10-15%
  • Resistance Training: Increases GLUT4 transporters

Research: Arizona State University found vinegar at mealtime reduces postprandial insulin by 20%.

4. Peptide YY (PYY) – Fullness Hormone

Natural Stimulators:

  • Resistant Starch: 20g daily increases PYY by 45%
  • Medium-Chain Triglycerides: MCT oil increases PYY more than long-chain fats
  • Exercise: Aerobic exercise increases PYY for 24 hours post-workout

Data: University of Surrey found resistant starch from cooled potatoes increases PYY significantly.

24-Hour Hormone Balance Protocol:

7 AM: Protein breakfast (30g) → Increases PYY, decreases ghrelin
10 AM: Green tea → Improves insulin sensitivity
1 PM: Vinegar with lunch → Reduces insulin spike
4 PM: Fiber snack → Increases PYY
7 PM: Omega-3 rich dinner → Improves leptin sensitivity
10 PM: 7+ hours sleep → Normalizes all hormones
