Ozempic Protein Calculator
Work out how much protein you need per day on Ozempic. The calculator sets the 0.54g/lb (1.2g/kg) minimum recommended to protect muscle on semaglutide, or 0.73g/lb (1.6g/kg) if you strength train.

This calculator provides general nutritional guidance based on scientific research. Before making significant changes to your diet or protein intake, especially if you have existing health conditions, kidney problems, or are pregnant or breastfeeding, please consult a qualified healthcare provider. If you are on prescription medication, follow your prescriber's advice first.
Protein on Ozempic: The Short Version
Ozempic (semaglutide) suppresses appetite so effectively that most people eat far too little protein without noticing. The risk is not hunger, it is muscle. When protein intake drops during rapid weight loss, your body pulls from lean mass as well as fat, which lowers your metabolism and makes regain more likely later.
The fix is a daily protein minimum of 0.54g per lb of body weight (1.2g per kg), in line with the 2025 expert consensus of 1.2 to 1.5g/kg (Sievenpiper et al., Obesity Pillars, 2025). If you strength train twice a week or more, tick the box above and the calculator uses 0.73g/lb (1.6g/kg).
Hitting Your Number When You Are Not Hungry
The practical challenge on Ozempic is volume. You may only manage a few small meals a day, so each one has to earn its place:
- Start every meal with the protein on the plate, not the carbs
- Keep small, dense options around: Greek yogurt, cottage cheese, jerky, eggs
- Use a shake to cover shortfalls; our guide to the best protein shakes for GLP-1 users compares the popular options
- On rough days, see what to eat on shot day

Track It or Lose It
Most Ozempic users who lose muscle never planned to. They just never counted. The Protein Pal app was built for exactly this: tell it you are on a GLP-1 and it sets your protein minimum, then logging each meal takes seconds. Free on iOS and Android.
Common Questions
- How much protein should I eat on Ozempic?
- At least 0.54g per lb of body weight per day (1.2g/kg). For a 180lb person that is roughly 98g of protein daily. Medical guidance suggests 0.54 to 0.73g/lb (1.2 to 1.6g/kg) during treatment.
- Can I lose muscle on Ozempic?
- Yes. Rapid weight loss on semaglutide can include significant lean mass loss if protein intake is low and you are not doing resistance exercise. Hitting a daily protein target is the main nutritional defense.
- Are protein shakes a good idea on Ozempic?
- They can be very useful. When appetite is heavily suppressed, a shake delivers 20 to 30g of protein in a small volume without requiring you to face a full plate of food.
