Short answer: A GLP-1 meal plan uses small, protein-first meals — around 25–30 g of protein each — with vegetables, slow carbohydrates and fluids between meals. It aims to protect muscle while appetite is low and to limit nausea. This page gives a full 7-day menu; agree calorie targets with your prescriber.
A GLP-1 meal plan is a low-volume, protein-dense eating pattern designed to work with the appetite suppression and slowed gastric emptying caused by semaglutide (Ozempic, Wegovy), tirzepatide (Mounjaro, Zepbound), liraglutide, and dulaglutide.
This 7-day plan delivers 110–130 g of protein, ~1,400–1,600 kcal, and 25–30 g fiber per day across 3 small meals and 2 protein snacks. It is built to protect lean muscle mass — the single biggest nutrition risk on GLP-1 therapy (Heymsfield et al., Lancet 2024).
⚠️ Medical disclaimer: Coordinate any major dietary change with your prescriber, especially if you take insulin or sulfonylureas.
Two Phases: Titration vs Maintenance
Phase
Weeks
Calories
Protein
Strategy
Titration
1–8 (dose escalation)
1,200–1,400
1.2 g/kg
Liquid-leaning, bland, small frequent meals
Maintenance
9+ (stable dose)
1,400–1,800
1.4–1.6 g/kg
Solid foods, full meal sequence, resistance training
This 7-day plan targets maintenance phase. For titration, halve dinner portions and add a second protein shake.
Core Rules
Protein first every meal (≥25 g)
Vegetables second, carbs last — blunts glucose spikes
Fluids between meals, not during — preserves stomach capacity
2.5–3 L water daily plus electrolytes
Resistance training 2–3x/week — non-negotiable for muscle preservation
1 electrolyte packet (low-sugar: LMNT, Liquid IV Sugar-Free) on training days
Coffee: cap at 2 cups, pair with water
Herbal tea, broth, sparkling water all count
Common Modifications
Vegetarian/vegan: Swap chicken/fish for tempeh, tofu, seitan, lentils, and pea protein shakes. Add B12 supplement (250 mcg/day).
Low FODMAP: Replace lentils, garlic, and onion with chicken/fish and chives. Berries and citrus stay in.
Severe nausea week: Drop solid breakfast, replace with 2 protein shakes spread over morning. Add ginger tea.
Plateau breaker: Increase protein to upper end (1.6 g/kg), add 20-minute walk after dinner, ensure 7+ hours sleep.
Common Questions
Why so much protein?
GLP-1 weight loss is up to 40% lean mass without adequate protein. 1.2–1.6 g/kg preserves muscle and metabolic rate (Heymsfield 2024).
Can I skip a meal if I am not hungry?
Replace it with a protein shake. Skipping entirely accelerates muscle loss.
Do I need supplements?
A daily multivitamin, vitamin D (2,000 IU), and B12 (250 mcg) cover the common gaps. Check with your prescriber.
Is this plan good for diabetes too?
Yes — same principles support glycemic control. See our diabetes diet guide for ADA-specific targets.
