Numbers that ensure you sustain your GLP-1 weight loss.

Engineered for the specific dietary needs of GLP-1 patients.

GLP-1 medications like semaglutide and tirzepatide are powerful tools for weight management and blood sugar control, but they create a specific nutritional challenge: when your appetite drops dramatically, every meal has to work harder. Without the right nutrition, the weight you’re losing isn’t just fat; it could be up to 40% muscle.

Muscle loss

Without adequate protein, GLP-1 users lose 25–40% of total weight as lean muscle mass. This leads to weakness, metabolic slowdown, hair thinning, and the premature aging sometimes called “Ozempic face.” You need 100–140g of high-quality protein per day from real food, not shakes, to protect what you’ve built.

Nausea and bloating

GLP-1 medications slow gastric emptying. High-fat, heavily spiced, and large-portioned meals become triggers. You need meals under 20g fat, 300–475 calories, without sacrificing protein density per calorie.

Malnutrition

When nothing sounds good, you skip meals and miss critical protein and micronutrient windows. Suppressed appetite makes it difficult to eat sufficient protein, fiber, vitamins, and minerals, leading to hair thinning, skin changes, and fatigue that have nothing to do with the medication itself. You need meals good enough that you actually want to eat them, and dense enough that every meal counts.

Every meal built around what GLP-1 medication does to your body.

Sustain isn’t a generic meal plan with a GLP-1 label. It’s a fundamentally different approach to which meals get selected for you, based on how semaglutide and tirzepatide change your digestion, appetite, and nutritional needs.

1. Lean protein prioritization

Every lunch and dinner delivers 35–50g protein from pastured chicken, wild-caught fish, shrimp, turkey, and other lean sources. Sustain deprioritizes heavier proteins and preparations that slow digestion, focusing instead on high protein density per calorie, the ratio that matters most when your appetite is suppressed.

2. Nausea-conscious formulation

Meals stay under 20g fat, use lighter sauce profiles and avoid the pungent aromatics (heavy curry, smoky BBQ) that are common nausea triggers for GLP-1 users. Lower fiber targets than our other programs because GLP-1 medications cause bloating.

3. Portioned for suppressed appetites

Standard meals are 300–475 calories. Large meals are 500–650 calories. Both deliver the protein density you need without the overwhelming portion sizes that make eating on GLP-1 medication feel impossible. Your body gets the nutrition. Your stomach doesn’t rebel.

4. Personalized to your biology

Share your bloodwork during signup (or just tell us what your doctor has flagged) and every meal in your plan gets weighted to move those markers. High cholesterol? More omega-3s. Blood sugar issues? Lower glycemic carbs. GLP-1 medication handles hunger. We handle everything else.

Our meals were the dietary intervention in a peer-reviewed clinical trial on blood sugar control.

Methodology meals were used as the dietary intervention in a randomized clinical trial studying how diet composition affects HbA1c, body weight, and fasting insulin in participants with prediabetes and type 2 diabetes. The results were published in the American Journal of Clinical Nutrition, one of the top-ranked nutrition journals in the world. Over 125,000 customers have eaten Methodology meals since we started 12 years ago. No other meal delivery company has this clinical foundation.

What GLP-1 users say about Sustain.

“I’ve been eating Methodology six meals a week for a year. Just got my annual results back — cholesterol dropped from 188 to 153, triglycerides from 151 to 55. You make it so easy.”
Karen C.

I’m Julie, co-founder of Methodology. I’m on tirzepatide.

I built Methodology 12 years ago because meals weighed to the gram, matched to bloodwork, and made from verifiable ingredients are one of the most powerful ways to noticeably improve health and quality of life.

When I started a GLP-1 microdose during late perimenopause, I realized that as incredible as Methodology was to pair with GLP-1, there was room to ensure those on GLP-1s could truly sustain their results and muscle: higher protein density in smaller volumes, lower fat to avoid nausea, lighter preparations that don’t trigger the gastric slowing these medications cause.

This is why we built Sustain. Every meal scoring rule, every sauce profile decision, every macro target comes from living on these medications and understanding what they do to your appetite, your digestion, and your relationship with food.

Everything GLP-1 users ask us.

What is the best meal delivery service for people on Ozempic or Wegovy?

Methodology’s Sustain GLP-1 program is purpose-built for GLP-1 medication users. Unlike generic meal services that add a GLP-1 label, Sustain was designed from the ground up around how semaglutide and tirzepatide change your digestion: lean protein prioritization (35–50g per meal), lighter fat profiles to reduce nausea, portions sized for suppressed appetites, and lower fiber targets to minimize bloating. Every meal is also gluten-free, dairy-free, and refined-sugar-free — cooked in avocado oil by Michelin-trained chefs.
Methodology is the only premium meal delivery service whose meals were used as the dietary intervention in a peer-reviewed clinical trial on blood sugar control, published in the American Journal of Clinical Nutrition.

How much protein do I need per day on a GLP-1 medication?

Research suggests GLP-1 users need 100–140g of protein per day to prevent the muscle loss that accounts for 25–40% of total weight lost on these medications. Sustain delivers 35–50g of protein per lunch and dinner from real food sources — pastured chicken, wild-caught fish, turkey, and shrimp — getting you to your daily target without shakes or supplements.

What should I eat on Ozempic to avoid nausea and bloating?

GLP-1 medications slow gastric emptying, which means high-fat, heavily spiced, and large-portioned meals become triggers for nausea and bloating. Sustain meals stay under 20g fat, use lighter sauce profiles (broth-based, citrus, ponzu), and are portioned at 300–475 calories standard — delivering maximum nutrition in volumes your stomach can handle.

How do I prevent “Ozempic face” and muscle loss on semaglutide?

“Ozempic face” and muscle wasting result from rapid weight loss without adequate protein intake. The solution is consuming 100–140g of high-quality protein per day from real food sources, combined with resistance training. Every Sustain meal delivers 35–50g protein from lean, easily digestible sources — so even when your appetite is suppressed, you’re protecting lean muscle mass with every meal you eat.

Can Methodology accommodate my food allergies?

Every Methodology meal is already gluten-free, dairy-free, and refined-sugar-free. You can further customize your plan during signup to exclude specific allergens. Our kitchen is designed around elimination-friendly cooking from the ground up — not as an afterthought.

How does delivery work?

Methodology ships to 48 states. Meals arrive fresh in insulated packaging with ice packs. Your delivery day is determined by your zip code to ensure optimal freshness. Meals last 5-7 days in the refrigerator (and many are freezer-friendly) and are ready to eat in under 5 minutes.

How much does it cost?

Pricing varies by plan size and meal frequency. Build your plan to see exact pricing tailored to your selections. There is no commitment — you can skip or cancel anytime.

What biomarker personalization is available?

Upload your bloodwork during signup — or simply tell us what your doctor has flagged — and your meal plan gets weighted to address those markers. High cholesterol triggers more omega-3-rich selections. Blood sugar concerns shift you toward lower glycemic carb profiles. Your plan adapts to your biology, not the other way around.

Is Methodology safe to use with my GLP-1 medication?

Methodology meals are real food — pastured proteins, vegetables, healthy fats, and complex carbohydrates. There are no supplements, additives, or pharmaceutical interactions. Sustain was specifically designed around the digestive changes GLP-1 medications cause. As always, consult your prescribing physician with specific medical questions.

What’s the difference between Sustain GLP-1 and Methodology’s Signature program?

Both programs share the same ingredient standards, but Sustain is specifically engineered for GLP-1 users: higher protein density per calorie, lower fat profiles to reduce nausea, lighter sauce preparations, smaller portions suited to suppressed appetites, and lower fiber targets to minimize bloating. Signature is our original program for customers not on GLP-1 medications who want precision nutrition matched to their bloodwork and goals.
