Plant-based eating and a GLP-1 work together fine — the challenge is the same as for anyone on these medications: getting enough protein in a small volume of food. The key is choosing the most protein-dense plant sources and combining them across the day.
Most protein-dense plant options
Approximate protein per common serving (check labels — they vary):
| Food | Serving | Approx. protein |
|---|---|---|
| Seitan | 3 oz | ~20 g |
| Tofu (firm) | ½ cup | ~10–11 g |
| Tempeh | 3 oz | ~16 g |
| Edamame | 1 cup | ~18 g |
| Lentils | ½ cup cooked | ~9 g |
| Pea/soy protein shake | 1 scoop | ~20–25 g (varies by brand/scoop) |
| Black beans / chickpeas | ½ cup | ~7–8 g |
| Soy milk | 1 cup | ~7 g |
A few things to know
- Combine sources for completeness. Most single plant foods are lower in one or two amino acids; eating a variety across the day (e.g. legumes + soy + grains) covers the full set — you don’t need to combine them in the same meal.
- Shakes carry the low-appetite days. A pea or soy protein shake is often the easiest way to add 20–25 g without much volume.
- Watch the volume trap. Beans and lentils are healthy but bulky for the protein they provide — lean on soy foods, seitan, and shakes when appetite is the limit.
On a plant-based GLP-1 plan, soy foods, seitan, and a good shake do the heavy lifting — variety across the day fills in the rest.
General nutrition education, not personalized advice — a registered dietitian (especially one familiar with plant-based eating) can help you build a complete plan.
