Semaglutide works largely by shrinking your appetite — which means the food you do eat matters more, not less. Eating well on a GLP-1 both improves results and prevents most of the common side effects. Here's a practical guide.
The core principle: protein first
When you're eating less overall, protein protects your muscle while the scale drops. Aim to build each meal around a protein source — eggs, poultry, fish, lean beef, Greek yogurt, cottage cheese, tofu, legumes — and eat it first, before sides. Many clinicians suggest roughly 0.5–0.7 g of protein per pound of goal body weight per day; your provider can personalize this.
Foods that tend to work well
Lean proteins; vegetables and fruit for fiber and micronutrients; slow-digesting carbs like oats, beans, and whole grains in modest portions; and plenty of water. Fiber keeps digestion moving — helpful because slowed gastric emptying can otherwise mean constipation.
Foods that commonly cause trouble
Because semaglutide slows stomach emptying, heavy foods sit longer. The most common nausea triggers are greasy and fried foods, very rich or creamy dishes, large portions of red meat, very sugary desserts and drinks, and carbonated beverages. Alcohol often hits harder and adds empty calories — many people naturally cut back.
How to eat, not just what
Smaller portions, eaten slowly, stopping at the first sign of fullness — overeating on a slowed stomach is the classic cause of nausea and reflux. Don't lie down right after meals, and spread fluids through the day rather than chugging with food.
Don't under-eat
Some people's appetite drops so much they eat too little protein and nutrients. That costs muscle and energy. If you're struggling to eat enough, tell your provider — dose pacing and meal strategies can help. Use our TDEE calculator to sanity-check your intake against your actual energy needs.
A sample day
Breakfast: Greek yogurt with berries and a spoon of granola. Lunch: grilled chicken salad with olive-oil dressing. Snack: cottage cheese or a protein shake. Dinner: salmon, roasted vegetables, and a small portion of rice. Adjust portions to your appetite — quality stays the same. The same principles apply on tirzepatide; see our tirzepatide timeline guide for how appetite changes evolve.
