There’s no single diet to follow while you are taking a GLP-1 medication, but eating more protein and fiber can help with weight loss and reduce side effects like nausea. Food choices affect how you feel while you are taking a GLP-1 medication. Many people notice that some foods make side effects better or worse.
Foods That Tend to Work Well while you are taking a GLP-1 medication.
There isn’t a single right way to eat while following this type of protocol; however, research suggests that food quality, portion size, and meal timing all play a role in weight-loss outcomes. Certain foods may contribute to side effects and weight gain, while others may support your overall health while promoting weight loss.
The best foods to eat on a GLP-1 diet include:
- Lean protein (chicken, turkey, fish, eggs, tofu, lean beef or pork)
- Low-fat dairy (Greek yogurt, low-fat yogurt, cottage cheese)
- Non-starchy vegetables (leafy greens, peppers, mushrooms, asparagus, squash, carrots)
- Nuts and seeds (almonds, walnuts, chia, pumpkin seeds, nut butter)
- Legumes (lentils, beans, chickpeas, edamame, peanuts)
- Whole grains (oatmeal, brown rice, quinoa, popcorn, whole wheat bread)
- Fresh fruit (berries, apples, bananas, melons, peaches, kiwis)
- Healthy fats in moderation (oily fish, olive oil, avocado, seeds, nuts)
Choose more of these foods to help you feel full, get enough nutrients, and manage side effects. Whole fruits are better than juice. Stick with unsaturated fats most of the time.
Foods Some People Choose to Limit while you are taking a GLP-1 medication.
These foods tend to worsen side effects like nausea, heartburn, bloating, or constipation, and/or are high in calories. These include :
- Fried or greasy foods
- Fatty cuts of meat
- Ultra-processed foods and fast foods
- Sugary drinks and desserts
- Alcohol
- Spicy foods
- Citrus fruits and tomatoes
- Garlic and onions
Not everyone reacts the same way to the same foods. If a food doesn’t worsen your symptoms, there’s usually no reason to eliminate it — and if something consistently causes discomfort, take a break from it, even if it’s generally considered “healthy.”
Generally, side effects are worse when you start taking the medication and when you increase your dosage. As such, you might find that some foods are hard to tolerate in the beginning, but easier to eat once your body gets used to your medication.
How Many Calories Should You Eat while you are taking a GLP-1 medication?
A caloric deficit can help you lose weight faster. This basically means that you take in fewer calories than you burn every day.
Staying in a calorie deficit is often easier with GLP-1 medications because they reduce appetite, increase feelings of fullness, curb cravings, and regulate blood sugar levels.
At the same time, you don’t want to eat too few calories. This can lead to nutritional deficiencies, fatigue, brain fog, and even long-term health problems.
Other Ways to Help Reduce Side Effects
Along with adjusting food choices, these everyday healthy eating habits may help ease common side effects and make it easier to stick to a healthy diet.
- Eat smaller portions and stop when you feel comfortable.
- Sip water throughout the day.
- Choose bland foods if nausea flares.
- Take short walks after meals to aid digestion.
- Plan your meals to make it easier to stick to a balanced diet.
- Keep a food log to notice patterns of side effects.
If side effects are persistent or disruptive, it’s important to follow up with the healthcare provider who prescribed your GLP-1 medication. They can help adjust your treatment plan or discuss supportive options.
Bottom Line
There’s no one-size-fits-all diet while you are on a GLP-1 diet, but certain foods may help with weight management, while others can worsen side effects and make it harder to lose weight.
Here’s what to keep in mind:
- Whole foods are generally best. Focus on proteins, fresh veg and fruit, whole grains, and healthy fats.
- Some foods can trigger the side effects of GLP-1 medication. For example, greasy, spicy, or high-fat foods may set off heartburn or nausea.
- Certain lifestyle changes may help. Staying hydrated, meal planning, and eating smaller portions may help you manage side effects while losing weight.
Ultimately, the important thing is to pay attention to your body. Everybody reacts differently to different foods, so noticing your own triggers is the key to feeling well while you are taking a GLP-1 medication.
