GLP-1 Protein Goals: How Much Protein Per Day on Ozempic or Mounjaro?

When your appetite shrinks on Ozempic, Wegovy or Mounjaro, protein is usually the first thing to slip. Meals get smaller, meat can feel heavy, and suddenly you are eating 50 grams a day without noticing. That matters, because protein is what helps you keep muscle while the scale drops. Here is how much to aim for, and how to get there when you are rarely hungry.

Why protein matters more on a GLP-1

GLP-1 and GIP/GLP-1 medications reduce hunger and slow stomach emptying. That is why they work, but it also means you eat less of everything, including the nutrients that protect lean mass. In large trials such as STEP-1 (semaglutide) and SURMOUNT-1 (tirzepatide), a meaningful share of weight lost was lean mass, commonly reported at roughly a quarter to a third of the total, though body-composition results vary by study and person.

Protein, paired with resistance exercise, is the main tool you control. It also helps with fullness, steadier energy and recovery. For more on this, see our guide to protecting lean muscle on GLP-1s.

How much protein per day: the numbers

There is no single official target for people on GLP-1s, but a 2025 joint advisory from several obesity and nutrition medical societies, along with other expert reviews, points to a range higher than the standard minimum of 0.8 g per kg of body weight.

• General starting range: about 1.2 to 1.6 g of protein per kg of body weight per day (roughly 0.55 to 0.73 g per pound).
• Practical shortcut: many clinicians suggest 60 to 90 grams a day as a floor for most adults, and some advise higher if you are lifting weights.
• Example: at 90 kg (about 200 lb), 1.2 to 1.6 g/kg is roughly 108 to 144 grams per day.
• If you have kidney disease or another condition affecting protein tolerance, do not raise your intake without your clinician’s guidance.

If you are well above a healthy weight, some dietitians calculate from an adjusted or goal body weight instead of your current weight. Ask your care team or a registered dietitian which number fits you.

What 25 to 30 grams of protein looks like

Spreading protein across the day works better than trying to eat it all at dinner. Three meals of 25 to 30 grams, plus a snack, gets most people into range.

• 3/4 cup plain Greek yogurt: about 15 to 18 g
• 3 eggs: about 18 g
• 3 oz cooked chicken breast or fish: about 21 to 26 g
• 1/2 cup cottage cheese: about 12 to 14 g
• 1 scoop whey or pea protein: about 20 to 25 g
• 1/2 cup cooked lentils: about 9 g
• 4 oz firm tofu: about 9 to 10 g

Tips for eating protein with a small appetite

1. Eat protein first. Take a few bites before anything else, while your appetite is at its best.
2. Go liquid or soft when solids are hard. Protein shakes, smoothies, yogurt, soups and scrambled eggs often sit better during nausea or after a dose increase.
3. Eat small and often. Four to five mini meals can feel easier than three full plates.
4. Choose lean, low-fat options. Greasy or fried foods can worsen nausea and reflux on slower digestion.
5. Track for a week. A quick log shows whether you are really at 50 grams or 100 grams.

The constipation catch

Raising protein, especially from shakes, bars or heavy meat, without raising fiber and fluids can make GLP-1 constipation worse. Aim to add fiber gradually, drink water through the day, and move after meals. Our post on Ozempic constipation and how to fix it walks through what helps, and the Mounjaro and tirzepatide strategies cover dose-increase weeks specifically.

Pair protein with strength training

Protein alone will not fully protect muscle. Two to three sessions a week of resistance work, whether bodyweight, bands or weights, gives your body a reason to hold on to lean tissue. Even a short routine counts.

When to talk to your provider

Call your care team if you cannot keep food down, are losing weight very quickly, feel persistently weak or dizzy, or have kidney or liver conditions. They can adjust your plan or refer you to a dietitian.
