Summer 2026 5 How to eat well while on GLP-1 medications You’ve seen the TV ads about GLP-1 weight-loss medications—and maybe you’ve wondered if they could help you. GLP-1s (glucagon-like peptide-1 receptor agonists) mimic the natural GLP-1 hormone our bodies make when we eat. They were first approved to improve blood sugar (blood glucose) control in people with type 2 diabetes. But some GLP-1 medications are now prescribed to treat obesity. They have several effects in the body, including working in the brain and stomach to help control hunger and help people feel satisfied with smaller portions, says Marcela Hinojosa-Clapp, MD, a family and obesity medicine physician. “One of the ways these medicines work is by helping reduce hunger and increase the sense of fullness after eating,” she says. Nutrition and GLP-1s If you’re prescribed a GLP-1, lifestyle changes such as eating smaller, balanced meals may help you get the right nutrients and have fewer side effects. Prioritize lean proteins such as fish, chicken, tofu and legumes. Choose balanced, nutrient-dense foods such as vegetables, whole grains, fruits, legumes, and healthy fats—like nuts, seeds, avocado and olive oil. Be mindful of portion sizes. GLP-1s help you feel full sooner and slow how quickly food moves out of the stomach, so food stays there longer. Eating large portions may lead to side effects such as nausea and bloating. “If you feel full, stop eating and save any leftovers for the next meal,” Dr. Hinojosa-Clapp says. The importance of exercise Weight loss can also lead to some muscle loss, which may slow metabolism. “Muscle plays an important role in supporting metabolism and healthy weight loss, so preserving it is important,” Dr. Hinojosa-Clapp says. Add resistance (strength) exercises to your aerobic routine. “Resistance training helps preserve muscle and support a healthy metabolism as you lose weight,” Dr. Hinojosa-Clapp says. A whole-person approach Obesity is a complex, chronic disease with many contributing factors. It’s important to address lifestyle habits and underlying health issues, with regular monitoring and guidance from your doctor. Questions for your primary care provider Am I a candidate for GLP-1 medication? What side effects should I expect? How long will I need to take the medication? How should I adjust my nutrition and exercise habits? Is it safe to use someone else’s medication or buy it online?
