What helps, step by step
- Cut back on sugary and highly processed foods.
- Right after taking your dose, go easy on high-fiber foods.
- Eat smaller meals and stop when you feel full. The stomach empties more slowly because of these medicines.
- Eat slowly. Your brain needs time to notice when you feel full.
- Fatty, greasy, and sugary foods often cause symptoms, so limit them.
- Tell your prescriber if it does not ease. They may slow the dose increases, or they may suggest another GLP-1.
Use the GLP-1 interactions checker to check anything from the drugstore before taking it.
