What to eat on a GLP-1, GLP-3, or weight-loss peptide — without losing muscle, motivation, or your money.
GLP-1 receptor agonists, GIP/GLP-1 dual agonists, and the next-generation GLP-3 (GLP-1/GIP/glucagon) triple agonists work. The trial data is real. But appetite suppression is only half the story — what you eat in the months you take a peptide therapy decides whether the weight stays off after. MyNutriCart builds a physician-designed weekly plan around your medication, conditions, and grocery store.
Build my GLP-1 meal planNo calorie counting · No supplements · Real food only
Muscle protection first
GLP-1 weight loss runs ~25-40% lean mass if protein is too low. Your plan targets 1.4-1.6 g/kg/day protein (per ASN/ESPEN), distributed across every meal so you preserve the muscle you have.
Anti-nausea sequencing
Slowed gastric emptying makes greasy, sugary, and oversized meals miserable. Plans lead with lean protein + soluble fiber, time fats away from injection days, and cap meal volume so you actually finish what's on your plate.
Low-glycemic core
Mediterranean / DASH-hybrid pattern — vegetables, legumes, whole grains, fatty fish 2-3×/week, whole dairy only. Aligns with ACC/AHA + ADA 2024 evidence for sustained metabolic improvement.
How your GLP-1 plan gets built
- 1
You tell us your medication, conditions, and grocery store
Onboarding asks for your weight, height, activity, current GLP-1 or GIP agonist (semaglutide, tirzepatide, liraglutide, dulaglutide, exenatide), any other conditions (Type 2 Diabetes, hypertension, fatty liver, etc.), allergies, and which grocery store you actually shop at.
- 2
A physician-designed AI builds your week
The plan applies the right calorie target for your BMI (1-2 lb/wk loss tier), the right protein floor for muscle protection, and the right macronutrient distribution for your other conditions — all from evidence-based guidelines (ACC/AHA, ADA, ESPEN, AND).
- 3
Your grocery list goes straight to Kroger or Instacart
One tap sends the whole week's grocery list to Kroger.com (Harris Teeter, Fred Meyer, etc.) or to an Instacart shopping link. No re-entering items. No off-brand swaps. Real prices from your store.

The coach adjusts as you go
Nauseated on injection days? Don't feel like cooking? Eating out? Chat with the coach. It logs deviations, swaps meals, and learns your patterns so the plan gets more useful every week.
The part most apps miss
Most weight-loss apps were built for the calorie-counting era. They ask you to log every bite. That doesn't work on a GLP-1, GIP/GLP-1, or GLP-3 peptide therapy — you're already eating less by default. The problem isn't intake. It's composition.
When the SURMOUNT-1, STEP, and emerging TRIUMPH-class retatrutide trials looked closely at body composition, between ~25% and ~40% of the weight people lost on these peptides was lean tissue — bone, muscle, organ mass. That's a sarcopenia signal. The fix is straightforward nutrition: enough protein per meal, enough resistance activity in the week, and a meal structure that doesn't feel awful when your stomach is empty for hours.
The newer GLP-3 / triple-agonist peptides (retatrutide is the most studied) push weight loss further than dual agonists, which makes the muscle-protection problem more urgent, not less. The same rules apply: prioritize protein, resistance-train, eat real food.
MyNutriCart is built around exactly that. A physician designed the rules. The AI follows them. You get a real plan, an organized grocery list, and a coach that adapts to your week — not another calorie tracker.
Common questions from GLP-1 users
Will I still be hungry on this meal plan?
No. The plan is anchored to your actual TDEE (Mifflin-St Jeor × your activity level) and accounts for the appetite suppression from your medication. You will not be told to eat 1,200 kcal on an injection day.
I have nausea on my injection day. What should I eat?
The plan prioritizes lean protein + soluble fiber (think egg whites + oats, Greek yogurt + berries, salmon + brown rice) on the day after injection, and pulls back on high-fat and high-volume meals. You can also chat the coach with "I'm nauseated" and get a quick swap.
Do you support retatrutide / GLP-3 / triple-agonist peptides?
Yes. Retatrutide (Eli Lilly's GLP-1/GIP/glucagon triple agonist) drives even larger weight loss than dual agonists in phase-2 data, which makes the muscle-preservation nutrition strategy more important, not less. The plan applies the same physician-designed rules: protein floor by body weight, anti-nausea food sequencing, and a low-glycemic core. As of writing, retatrutide is not yet FDA-approved — only use it if your prescribing physician is supervising.
What about other weight-loss peptides (CagriSema, survodutide, orforglipron)?
The nutrition principles are class-wide: peptide therapies suppress appetite via gut hormone signaling, so what you DO eat needs to deliver more protein, more fiber, and more anti-inflammatory whole foods per bite. The plan adapts to any GLP-1, GIP, GLP-3, glucagon-receptor, or amylin-class peptide — you just tell the coach what you're on.
Do I need to keep MyNutriCart after I stop the medication?
That's the point of building the right habits now. Every weekly plan reinforces a Mediterranean / DASH pattern, enough protein, and real food. When you taper or stop, you have a months-long playbook for what to eat — not a cliff to fall off.
Is this safe with my other conditions?
Yes — every condition you select (Type 2 Diabetes, hypertension, fatty liver, CKD not on dialysis, etc.) layers its own evidence-based rules on top. The plan never optimizes for one condition at the expense of another. Some severe conditions are hard stops and the app will recommend you work directly with your physician.
