The GLP-1 Macronutrient Framework
This isn't a diet — it's a priority system. When your appetite is suppressed and your calories drop, the order in which you choose your nutrients determines whether you lose fat and keep muscle or lose both. The research is clear on the targets.
A 2025 study published in Frontiers in Nutrition found that only 43% of GLP-1 users hit the minimum protein target. The average was 18.5% of calories from protein — when research calls for 30–35%. The consequence is that up to 50% of weight lost comes from muscle, not fat. That's not what any of us signed up for.
The rule is simple: 20–35 grams of protein at every eating occasion. Not once a day — every time you eat. Spread through meals is what drives muscle protein synthesis.
- Greek yogurt (plain, full-fat) — 17–20g/cup
- Eggs — 6g each, versatile, easy on nausea
- Cottage cheese — 25g per cup, underrated
- Chicken breast — 31g per 100g, lean
- Salmon — 25g + omega-3s for inflammation
- Canned tuna or sardines — fast, high-protein
- Lean ground turkey — flexible, easy to portion
- Edamame — 17g/cup, plant-based complete protein
- Whey or plant protein powder — when appetite is low
- Lentils — 18g/cup + fiber double benefit
- Protein bars with 10g or less — marketing, not food
- Flavored yogurt — sugar + protein ratio is wrong
- Deli cold cuts as a protein strategy — sodium load
- Protein shakes as meal replacement daily — real food first
- Plant "protein" pasta under 10g per serving
- Fried chicken — protein exists, fat overwhelms
- Cheese as your protein source — fat-to-protein ratio off
Eat This, Not That — Protein Swaps
GLP-1 already slows gastric emptying — which means fiber-rich carbs pair naturally with how the medication works. Soluble fiber (oats, chia, psyllium) softens stool and reduces constipation — one of the most common GLP-1 complaints. Complex carbs provide sustained energy without the blood sugar crash that drives cravings. Don't eliminate carbs. Redirect them.
- Oats — soluble fiber, sustained energy, easy on GI
- Sweet potato — fiber + potassium + gentle carbs
- Lentils & chickpeas — fiber + protein double win
- Chia seeds — 10g fiber per oz, sprinkle on anything
- Berries — low sugar, high fiber, antioxidant rich
- Quinoa — complete protein + complex carb
- Brown rice — whole grain, pairs with everything
- Black beans — 15g fiber per cup
- Psyllium husk — constipation support, start slow
- Leafy greens — volume, micronutrients, near-zero calories
- White bread and bagels — fast glucose spike, no fiber
- Sugary cereals — even "healthy" ones
- Fruit juice — fiber removed, sugar concentrated
- Crackers as a snack base — refined, low fiber
- White pasta in large portions — swap or reduce
- Sweetened oatmeal packets — hidden sugar load
- Sports drinks — glucose without fiber or protein
Eat This, Not That — Carb Swaps
Fat is not the enemy — high-fat meals are the enemy on GLP-1 therapy. When GLP-1 slows gastric emptying and you add a high-fat meal on top, the result is prolonged nausea, bloating, and a miserable experience. Most people who "can't tolerate" their medication are eating too much fat too fast. Reduce portion sizes of fat at meals — you don't have to eliminate, just moderate.
- Avocado — healthy fat, potassium, portion control matters
- Extra virgin olive oil — anti-inflammatory, use for cooking
- Walnuts and almonds — omega-3, eat by the small handful
- Salmon and mackerel — fat + protein + omega-3 trifecta
- Chia and flax seeds — plant omega-3, easy to add
- Full-fat Greek yogurt — the fat slows digestion usefully here
- Eggs (the yolk included) — choline + fat-soluble vitamins
- Fried foods — fat volume + delayed emptying = nausea
- Butter-heavy cooking — use sparingly, switch to olive oil
- Full-fat cheese in large amounts — easy to overdo
- Coconut oil in large quantities — high saturated fat
- Creamy sauces and dressings — hidden fat loads
- Processed meats (bacon, sausage) — fat + sodium + low quality

A Real Day of Eating on GLP-1
This isn't a strict plan — it's a template showing how the macros actually look in real food. Cheryl's version. Portions sized for someone eating less due to medication-suppressed appetite.
The Body Reality Section
Loose skin is not a failure. It is evidence. When you lose 50, 80, 100+ pounds, your skin — which stretched over years to accommodate the weight — does not snap back on a timeline you get to choose. Some of it will tighten over months. Some of it won't. Both outcomes are normal.
The things that genuinely help: adequate protein (your skin is made of collagen — collagen requires protein), hydration, resistance training to build the muscle that fills the space underneath, and time. GHK-Cu peptide has real research behind it for collagen regeneration — we cover that in the skin guide. Red light therapy has emerging data for skin tightening — we cover that too.
What doesn't help: shame about it. The skin you're worried about is the same skin that carried you through everything that got you here. You're not less of a success because your body has a map of the journey. Cheryl and I have both sat with this reality. It doesn't go away, but it changes how you hold it.
The nutrition connection: collagen synthesis requires vitamin C, protein, zinc, and copper. Eating for skin health is not a separate protocol — it's the same protein-forward framework above, plus making sure you're not deficient in the micronutrients collagen production depends on. Bone broth is a genuinely useful addition here — not magic, but real collagen precursors in a form that's easy on a suppressed appetite.
"I am not a nutritionist and neither is Cheryl. What we are is people who have been on this road for years and paid attention. The biggest thing I've learned about eating on GLP-1 is that the medication does not care what you eat — it just makes you eat less. What you choose to eat with that reduced appetite is entirely on you, and it matters more than most people realize. Protein first. Every time. And stop being afraid of your body. It's doing something remarkable."
