Appetite Suppression
Reduced hunger and cravings for easier calorie control.
TL;DR
Appetite suppression is safest and most durable via protein intake, fiber, and sleep. Whey protein and viscous fiber (psyllium) increase satiety in trials; stimulant-based suppressants trade short-term effect for side effects.
Why It Matters
Appetite is regulated by ghrelin, GLP-1, PYY, CCK, and leptin signaling. Protein is the most satiating macronutrient; viscous fiber slows gastric emptying and blunts postprandial glucose. Chronic sleep deprivation elevates ghrelin. Supplements work best as meal-structure tools (preloads), not as standalone appetite blockers.
How to Measure
Rate hunger on a 0–10 scale before and 2 hours after meals for 2 weeks; track ad libitum intake at a consistent test meal.
Biomarkers
Optimization Protocol
Whey protein 25–30 g as a preload 30 min before the largest meal. Psyllium husk 5–10 g with 300+ ml water before meals (separate from medications by 2 hours). Hit 1.2–1.6 g/kg/day total protein.
Lifestyle Levers
- •7–9 hours sleep
- •High-protein breakfast
- •Meal volume from vegetables
- •Limit liquid calories and hyperpalatable snacks
