If you are taking a GLP-1 medication such as Ozempic, Wegovy, Mounjaro, or Zepbound, you are one of millions of Americans using these treatments. Over 10 million adults in the United States now use a GLP-1 medication, and that number continues to grow rapidly. These medications are powerful tools for weight loss and blood sugar control, but what you eat and drink still matters. Use the simple MEAL framework to get the most out of your treatment.
M — Muscle Maintenance
Weight loss can mean losing muscle, not just fat. Protect your muscles by eating protein at every meal — and eating it first. Good sources include fish, eggs, Greek yogurt, cottage cheese, chicken, beans, and nut butters. Pair this with regular strength training (weights, resistance bands, or bodyweight exercises). Protein alone is not enough — exercise sends the signal your body needs to hold on to muscle.
E — Energy Balance
Because your appetite is smaller, make every bite count. Choose nutrient-dense foods: fruits, vegetables, whole grains, lean proteins, nuts, and healthy fats like olive oil and avocado. Eat small, regular meals at consistent times — do not skip meals even if you are not hungry. Limit refined carbohydrates, sugary drinks, fast food, and heavily processed snacks.
A — Avoid Side Effects
- Stomach side effects are common but manageable through diet:
- Nausea: Eat small meals every 3–4 hours. Avoid greasy or fried foods. Try ginger or peppermint tea. Do not skip meals — an empty stomach makes nausea worse.
- Heartburn: Eat small portions, avoid spicy or high-fat foods and stay upright for 2-3 hours after eating.
- Constipation: Drink plenty of water, increase fiber gradually, and try prunes or dried fruits.
L — Liquid Intake
When you eat less, you also get less water from food, raising your risk of dehydration. Aim for at least 8–12 cups (2–3 liters) of water daily. Eat water-rich foods like cucumbers, watermelon, oranges, and soups. Carry a water bottle and sip throughout the day.
One More Thing: Vitamins
Eating less overall means you may fall short on certain vitamins and minerals. Ask your doctor whether a daily multivitamin or supplements like vitamin D, calcium, or B12 are right for you.
The Bottom Line
Remember MEAL: Muscle maintenance, Energy balance, Avoid side effects, Liquid intake. These four steps will help you get the best results from your GLP-1 medication. If you are struggling with side effects or unsure about your diet, ask your healthcare team about a referral to a registered dietitian.
