This guide is for general education, not medical or nutrition advice. Food tolerance is individual — if a side effect is severe or persistent, talk with your provider.
Semaglutide and tirzepatide work in part by slowing how quickly food leaves your stomach. That's part of what makes you feel full on less — but it also means foods that are already slow to digest, like fatty or fried foods, can sit uncomfortably and trigger nausea or bloating, especially in the days after a dose increase.
| Limit | Why | Better swap |
|---|---|---|
| Fried or greasy foods | High fat slows digestion further, worsening nausea | Grilled, baked, or air-fried versions |
| Large, heavy meals | Harder to tolerate once gastric emptying slows | Smaller, more frequent meals |
| Carbonated drinks | Can increase bloating and stomach discomfort | Still water, herbal tea, electrolyte drinks |
| Alcohol | Can worsen nausea and dehydration | Limit intake, especially around dose increases |
| Very sugary or processed foods | Can cause blood sugar swings and GI upset | Whole fruit, naturally sweet options |
| Spicy or heavily seasoned foods | Can trigger reflux for some people | Milder seasoning, introduce gradually |
| Very fibrous raw vegetables in large amounts | Can be harder to digest on a slower stomach | Cooked or steamed vegetables in smaller portions |
