One of the best things you can do to feel your best on GLP-1 medication is to eat the right foods. Since these medications slow down digestion and reduce appetite, what you eat matters more than ever.
This guide covers practical, easy-to-follow nutrition tips for semaglutide and other GLP-1 medications.
Why Nutrition Matters on GLP-1 Medication
GLP-1 medications work by slowing digestion and signaling fullness to your brain. This means:
Eating the right foods helps you feel great, avoid side effects, and get the most out of your treatment.
Foods to Eat (The "DO" List)
### 1. Lean Protein Protein helps preserve muscle mass during weight loss, supports your metabolism, and keeps you full.
*Great sources:*
Aim for: 25-30 grams of protein per meal
### 2. Non-Starchy Vegetables These provide fiber, vitamins, and volume without too many calories.
*Great choices:*
Aim for: Fill half your plate with vegetables
### 3. Complex Carbohydrates Choose carbs that provide sustained energy and fiber.
*Great sources:*
### 4. Healthy Fats Fat helps your body absorb nutrients and keeps you satisfied.

Foods to Limit or Avoid (The "DO NOT" List)
### 1. Fatty, Fried, and Greasy Foods These can trigger nausea and digestive discomfort. The slowed digestion from GLP-1 means that greasy foods take even longer to process.
Avoid: Fried chicken, french fries, heavy cream sauces, processed meats, pizza with heavy cheese
### 2. Ultra-Processed Foods Processed foods are low in nutrients and can cause blood sugar crashes.
Avoid: Packaged snacks, sugary cereals, frozen meals with added sugar, fast food
### 3. Sugary Drinks and Alcohol Liquid calories don't trigger fullness signals, and alcohol can be poorly tolerated on GLP-1 medications.
Avoid: Soda, sweetened coffee drinks, fruit juice, excessive alcohol
### 4. Large Meals Big meals can cause severe discomfort because digestion is slower.
Instead: Eat 4-6 small meals spread throughout the day
Sample Day of Eating
Breakfast (small): Greek yogurt with berries and a handful of nuts
Morning snack: Apple slices with almond butter
Lunch (medium): Grilled chicken salad with mixed greens, cucumber, vinaigrette
Afternoon snack: Red pepper slices with hummus
Dinner (small-medium): Baked salmon with roasted broccoli and quinoa
Evening: Herbal tea
Common Mistakes to Avoid
What About Caffeine?
Light-to-moderate caffeine is usually fine. Monitor how you feel, some patients find coffee on an empty stomach causes nausea. Try having it with or after food.
Meal Prep Tips
1. Prep protein in bulk (grill chicken, cook quinoa, hard-boil eggs) 2. Wash and cut vegetables for easy access 3. Portion out snacks into containers 4. Keep healthy options visible and accessible
Listen to Your Body
The most important rule is to listen to your body. GLP-1 medications change your relationship with food, and what works for someone else may not work for you. Start simple, pay attention to how foods make you feel, and adjust as you go.
