What foods should I avoid on a GLP-1?

Two different lists, two different reasons: List A — the “you’ll regret it physically” tier (slowed stomach mechanics): - Fried and high-fat meals — fat empties slowest; the burger-and-fries experiment on a fresh dose increase is the canonical GLP-1 mistake. Worst offenders: fried chicken, creamy pastas, fast food, fatty cuts in big portions. - Large portions of anything — volume is its own trigger; the buffet reflex now has a price. - Very sweet, rich desserts — concentrated sugar + fat on a slow stomach = nausea and “sulfur burp” lore. - Carbonated drinks — bloating and reflux on a stomach that’s already holding contents longer. - Spicy food — fine for many, a reflux amplifier for the prone; learn your line on a stable-dose week. The pattern: List A foods are worst in the 48–72 hours after dosing and during titration jumps. On stable maintenance doses, most people reclaim modest versions of all of them. List B — the “you’ll stall silently” tier (bypasses appetite suppression): - Caloric drinks: lattes, juice, soda, smoothie-shop “smoothies,” alcohol — satiety hormones police food far better than liquids; this is where most mystery plateaus live. - Grazeable ultra-processed snacks — chips, candy, crackers eaten by the handful skip the meal-fullness machinery; not evil, just untracked. What this page deliberately doesn’t say: no food “interferes with the medication,” no detox rules, no banned lists to memorize. Grapefruit is fine (no CYP interaction drama here). The drug works regardless; these lists are about comfort and throughput — and the positive version of the same advice is in what to eat.
