GLP-1 nutrition: guides, meal plans and data
Eating well on GLP-1 medication mostly comes down to protein first, small plain portions, and some strength work. These guides turn that into meals, swaps and numbers, and our data pages show what members using these medicines actually log.
Key facts
ParrotPal publishes free guides for people using GLP-1 medication such as Mounjaro, Wegovy, Ozempic and Zepbound: meal plans, protein targets and what to limit. They are general information, not medical advice, and never advise on doses or side effects. Your prescriber, GP or pharmacist is the person to ask about your medicine.

What the research says
A 2025 joint advisory from four US nutrition and obesity societies notes that higher protein targets, such as 1.2–1.6 g per kg a day, have been proposed during active weight reduction (or an absolute 80–120 g a day), and that protein intake in adults should not fall below 0.4–0.5 g per kg a day.

Obesity 33(8):1475–1503. doi:10.1002/oby.24336
In the STEP 1 trial, body scans in a substudy found lean mass made up about 4 in every 10 kilos lost (5.3 kg of 13.6 kg). Lean mass includes muscle, organs and water.

In a body-scan substudy of the SURMOUNT-1 trial (160 people), about 75% of the weight lost was fat and 25% lean mass, the same split as in the placebo group.

Questions people ask
What should I eat on GLP-1 medication?
Protein first at each meal, then vegetables or fruit, then starchy food if there’s room, in small, plain portions. The GLP-1 diet plan and the 7-day meal plan turn that into meals.
Does ParrotPal prescribe or sell GLP-1 medication?
No. ParrotPal is a food and habit tracking app. It doesn’t sell, supply or recommend any medicine.
