What should you eat on a GLP-1 (and what to avoid)?

Reviewed by the glpzoom Editorial Team against primary clinical sources — FDA labeling, peer-reviewed trials, and specialty-society guidelines.

On a GLP-1, appetite drops sharply, so the goal shifts from eating less to eating well within a smaller window. Prioritize protein — 80-100g/day for most adults — to protect lean muscle, which GLP-1 weight loss can otherwise erode. Good sources: eggs, Greek yogurt, chicken, fish, tofu, legumes, protein shakes. Add fiber (vegetables, berries, whole grains) for satiety and to ease the constipation GLP-1s often cause, and drink more water than feels natural because thirst cues also blunt. What to limit: high-fat and fried foods (they sit heavily on delayed gastric emptying and trigger nausea), large portions (eat slowly, stop early), carbonated drinks and alcohol (amplify GI discomfort), and refined sugar (spikes that undercut the metabolic benefit). Many patients find smaller, more frequent protein-forward meals tolerate better than three large ones. If nausea is bad, bland low-fat foods (rice, toast, broth, banana) help during titration weeks. None of this is a special 'GLP-1 diet' product — it's standard protein-forward eating adapted to a smaller appetite.

Related questions

  • Does Ozempic or Wegovy affect birth control?

    Semaglutide (Ozempic, Wegovy) does not chemically weaken birth control, but vomiting or diarrhea from GI side effects can reduce oral-pill absorption. Tirzepatide (Mounjaro, Zepbound) does affect oral contraceptive absorption — use a backup barrier method for 4 weeks after each dose increase.

  • Can I drink coffee on Ozempic or Wegovy?

    Yes, coffee is fine on Ozempic and Wegovy — there's no interaction between caffeine and GLP-1 drugs. Drink it with food rather than on an empty stomach if it worsens nausea or reflux, and limit sugary coffee drinks that work against the metabolic benefit.

  • How should you exercise on a GLP-1?

    On a GLP-1, prioritize resistance training 2-4x/week over cardio to protect the lean muscle that weight loss can erode (20-40% of weight lost can be muscle). Pair it with 80-100g protein daily, stay hydrated, and don't over-train in a steep calorie deficit.
