Wegovy Protein Calculator
Find your daily protein goal on Wegovy. The calculator sets the 0.54g/lb (1.2g/kg) minimum that helps you lose fat rather than muscle, or 0.73g/lb (1.6g/kg) if you strength train.
Medical Disclaimer
This calculator provides general nutritional guidance based on scientific research.

If you are on prescription medication, follow your prescriber's advice first.
Your Protein Goal on Wegovy
Wegovy (semaglutide) is approved specifically for weight loss, and the weight comes off fast. What the scale does not show is where it comes from. Without enough protein, a meaningful share of the loss is muscle, and that matters twice: once now, because muscle keeps your metabolism up, and once later, because lost muscle is the main reason weight creeps back after treatment ends.
The evidence-based answer is a protein minimum of 0.54g per lb of body weight per day (1.2g per kg), from a 2025 expert consensus recommending 1.2 to 1.5g/kg during GLP-1 weight loss (Sievenpiper et al., Obesity Pillars, 2025). If you strength train twice a week or more, the calculator uses 0.73g/lb (1.6g/kg). Enter your weight above for the exact number.
Making the Target Achievable
On Wegovy your appetite will not cooperate with big meals, so structure matters:
- Aim for 25 to 35g of protein at each eating occasion rather than one big dinner
- Lean on dense, low-volume sources; our high protein foods for low appetite guide lists the best ones
- A protein shake is a legitimate meal on days when solid food does not appeal
- Follow a plan if that helps: we published a 7 day high protein GLP-1 meal plan
And because muscle preservation is the whole point, pair the protein with resistance exercise. Our guide to strength training on a GLP-1 covers how to start.
Count What Counts
You do not need to track calories on Wegovy, the medication handles the deficit. You need to track protein. The Protein Pal app does exactly that one job, with a GLP-1 mode that sets this same target. Free on iOS and Android.
Common Questions
- How much protein do I need on Wegovy?
- A minimum of 0.54g per lb of body weight per day (1.2g/kg), with 0.54 to 0.73g/lb (1.2 to 1.6g/kg) recommended by medical society guidance. A 220lb person needs at least 120g of protein daily.
- Why does protein matter for keeping weight off after Wegovy?
- Muscle drives your resting metabolism. If you lose a lot of muscle during treatment, your body burns fewer calories afterwards, which makes regain more likely. Protecting muscle with protein during weight loss improves your odds of keeping the weight off.
- Is this different from the Ozempic recommendation?
- No. Wegovy and Ozempic are both semaglutide, just at different doses and approvals. The protein guidance is the same: at least 0.54g per lb (1.2g per kg) of body weight per day.
