At a glance: plant proteins on a GLP-1

Plant protein	Protein (per portion)	Notes
Seitan (3 oz)	~21 g	Highest protein/oz; not for gluten-free
Lentils (1 cup)	~18 g	Protein + fiber
Edamame (1 cup)	~17 g	Complete plant protein
Tempeh (½ cup)	~16 g	Fermented, hearty texture
Chickpeas/beans (1 cup)	~15 g	Versatile staple
Greek yogurt (1 cup, vegetarian)	~15–20 g	If vegetarian
Tofu (½ cup)	~10 g	Soaks up flavor

Nutrition values are approximate and vary by brand and preparation. Individualize targets with a clinician or registered dietitian. Information is current as of June 2026.

Why protein matters more on a GLP-1

GLP-1 receptor agonists meaningfully reduce appetite and calorie intake. In the STEP 1 trial of semaglutide 2.4 mg/week, participants lost a mean of roughly 15% of body weight over 68 weeks (Wilding et al., NEJM 2021). The SURMOUNT-1 trial of tirzepatide showed even larger losses — up to ~22% at the highest dose (Jastreboff et al., NEJM 2022). These are results from research on the branded molecules, not outcomes of any compounded product. The relevant point for nutrition: eating significantly less while losing weight at speed raises the stakes for protein. Inadequate protein during caloric restriction accelerates lean muscle loss, which slows metabolism and makes weight maintenance harder over time — a pattern the STEP 4 maintenance trial underscores (Rubino et al., JAMA 2021). The 2025 multi-society GLP-1 Nutrition Advisory recommends 1.2–1.6 g of protein per kg of body weight per day (ACLM/ASN/OMA/TOS advisory, 2025). For plant-based eaters, hitting that target requires a bit more planning because most plant proteins are less concentrated and sometimes incomplete compared to animal sources.

Which plant proteins work best on a GLP-1?

Build meals around legumes (lentils, beans, chickpeas), soy foods (tofu, tempeh, edamame), and seitan, plus eggs and dairy if you're lacto-ovo vegetarian. These are protein-dense enough to count even in the smaller portions a GLP-1 allows. Combine different sources across the day — legumes + grains, beans + seeds — to cover all essential amino acids. For the full protein-count breakdown across all eating patterns, see high-protein foods on a GLP-1 and how much protein you actually need on a GLP-1.

Easy high-protein plant meals

Breakfast: tofu scramble with greens, or Greek yogurt + berries + pumpkin seeds (vegetarian). Lunch/Dinner: lentil soup, tofu/tempeh stir-fry with edamame, chickpea bowls, bean chili. Add hemp or pumpkin seeds and a whole-food fat (avocado, olive oil, nuts) to round it out. For a structured week of meals, see the 7-day GLP-1 meal plan or the broader what to eat on a GLP-1 guide.

Nutrients to watch on plant-based GLP-1 diets

Plant-based eaters on a GLP-1 should pay extra attention to:

• Vitamin B12 — vegans need a daily supplement or fortified foods (nutritional yeast, plant milks). Deficiency is common on fully plant-based diets and isn't solved by GLP-1 medication.
• Iron — plant iron (non-heme) is less bioavailable than meat iron. Pair iron-rich foods (lentils, beans, seeds, fortified cereals) with vitamin C to improve absorption.
• Vitamin D — frequently low in the general population; reduced calorie intake can make it harder to reach from food alone. A daily supplement is often warranted.
• Omega-3s — chia seeds, flaxseed, and walnuts provide ALA; if you don't eat fatty fish, an algae-based DHA/EPA supplement covers the conversion gap.
• Fiber — legumes and vegetables are excellent fiber sources on a plant-based diet, which helps with GLP-1 side effects like constipation. See high-fiber foods on a GLP-1.

See the full supplement rundown in supplements worth considering on a GLP-1. And on whole-food vs. processed: favor whole-food legumes and soy over heavily processed meat substitutes, which tend to be high in sodium and lower in the fiber and micronutrients that support health on a reduced-calorie GLP-1 diet (Cleveland Clinic).

Can vegetarians and vegans qualify for a GLP-1 program?

Diet doesn't affect clinical eligibility. GLP-1 medications are prescribed based on health history, not what you eat. A U.S.-licensed physician reviews each intake and determines whether treatment is appropriate — not all applicants qualify. For a full overview of who qualifies, see do you qualify for a GLP-1? and the NIDDK resource on prescription weight-loss medications.

When prescribed, Nouri dispenses compounded semaglutide or compounded tirzepatide, prepared by state-licensed 503A compounding pharmacies — Jungle Jim's Pharmacy (Fairfield, OH) and VialsRX. Compounded semaglutide and tirzepatide are not FDA-approved and are not the same as the brand-name drugs Wegovy®, Ozempic®, Zepbound®, or Mounjaro®. For information on human drug compounding, see the FDA's compounding overview. Research on the brand-name molecules — including STEP 1 and SURMOUNT-1 — involved participants across all dietary patterns; there is no evidence vegetarian or vegan diets reduce their efficacy.

How Nouri supports vegetarian and vegan GLP-1 patients

Eating well on a GLP-1 is the difference between losing fat and losing muscle — and it's where most programs leave you on your own. Nouri's Program combines compounded GLP-1 medication (when prescribed) with a whole-food nutrition plan built around adequate protein and fiber, a movement plan to protect muscle, and unlimited concierge care from the Nouri Care Team to adjust everything as your appetite changes.

Plans start at $120/month for compounded semaglutide (6-month plan, $720 billed every 6 months) and $175/month for compounded tirzepatide (6-month plan, $1,050 billed every 6 months). Any dose, same price. For a full comparison of GLP-1 telehealth pricing, see the GLP-1 cost guide for 2026 or the openly-licensed Nouri GLP-1 telehealth pricing dataset.

Frequently asked questions

What can vegetarians eat on Ozempic?

Plenty of protein-dense plant and dairy foods: lentils, beans, chickpeas, tofu, tempeh, edamame, eggs, Greek yogurt, and cottage cheese, plus vegetables, whole grains, nuts, and seeds. Lead each meal with protein.

How do vegans get protein on a GLP-1?

From legumes (lentils, beans, chickpeas), soy foods (tofu, tempeh, edamame), seitan, and seeds, combined across the day for complete protein. Vegans should also supplement B12, monitor iron, and cover vitamin D.

What are the best plant-based proteins for a GLP-1?

Lentils (~18 g/cup), edamame (~17 g), tempeh (~16 g/½ cup), beans/chickpeas (~15 g/cup), seitan (~21 g/3 oz), and tofu (~10 g/½ cup) — all protein-dense enough for the smaller portions a GLP-1 allows.

Can you be vegan on a GLP-1?

Yes — with planning. Hit your protein target with legumes, soy, and seitan; combine sources for complete protein; lead meals with protein; and cover B12, iron, vitamin D, and omega-3s. Prioritize whole foods over processed substitutes.

What is a high-protein vegan meal plan on a GLP-1?

A simple day: tofu scramble with greens at breakfast, lentil soup at lunch, tempeh stir-fry with edamame at dinner — combining sources for complete protein, plus seeds, a whole-food fat, and supplements for B12, iron, and vitamin D.
