When you start taking GLP-1 medications like Ozempic or Wegovy for weight loss, one thing is clear: these drugs are game-changers in helping you shed pounds. But what about the weight you don’t want to lose—like muscle?
Losing muscle mass during weight loss is a common concern, especially for those on GLP-1 medications, which reduce appetite and can lead to lower calorie and protein intake. The big question is: can eating more protein protect your muscles while you’re losing fat?
In this article, we’ll dive into the science behind protein’s role in preserving muscle, how much you need, and whether a high-protein diet is enough to keep your strength and muscle mass intact while on GLP-1 medications.
Why Muscle Loss Happens During Weight Loss
Whenever you lose weight, the body sheds more than just fat. A small percentage of that weight—typically 25-30%—can come from lean body mass, which includes muscles.
This happens because:
- Calorie Deficits Affect All Tissues: Weight loss requires burning more calories than you consume, forcing your body to pull energy from fat and muscle stores.
- Decreased Protein Intake: Reduced appetite from GLP-1 medications may lead to lower protein consumption, which is essential for maintaining muscle.
- Less Physical Activity: Losing weight can sometimes make people feel less energized, leading to reduced exercise or strength training, further contributing to muscle loss.
How Protein Supports Muscle During Weight Loss
Protein is the building block of muscle. When you eat protein-rich foods, your body breaks them down into amino acids, which are used to repair and rebuild muscle tissue.
Without enough protein, your body struggles to maintain lean muscle, especially when you’re in a calorie deficit.
How Much Protein Do You Need?
While the general recommendation for protein intake is 0.8 grams per kilogram of body weight, people trying to preserve muscle during weight loss may benefit from consuming 1.2 to 2.0 grams per kilogram.
For example:
- To minimize muscle loss, a person weighing 150 pounds (68 kg) would need 82–136 grams of protein daily.
The Timing of Protein Intake Matters
Consuming protein throughout the day can optimize its muscle-preserving benefits. Spreading your intake across meals helps ensure your body has a steady supply of amino acids for muscle repair.
Ideal Protein Timing Tips
- Start Strong: Include high-protein foods like eggs, Greek yogurt, or protein shakes in your breakfast.
- Balanced Meals: To maximize muscle protein synthesis, aim for at least 20-30 grams of protein per meal.
- Post-Workout Nutrition: A protein-rich snack can help repair muscles and enhance recovery after strength training.
What Are the Best Protein Sources?
Whether you prefer animal or plant-based protein, there are plenty of options to meet your needs.
Animal-Based Proteins
- Chicken, turkey, and lean beef
- Fish and seafood (e.g., salmon, tuna)
- Eggs and egg whites
- Dairy products like Greek yogurt, cottage cheese, and milk
Plant-Based Proteins
- Lentils, chickpeas, and black beans
- Tofu and tempeh
- Quinoa, nuts, and seeds
- Plant-based protein powders
Can a High-Protein Diet Prevent Muscle Loss on GLP-1s?
The Good News
Studies suggest that high-protein diets can significantly reduce muscle loss during weight loss. Combining increased protein intake with strength training further enhances muscle preservation.
The Reality
While a high-protein diet can minimize muscle loss, it may not entirely prevent it, especially if you consume very few calories or skip exercise.
GLP-1 medications, which reduce hunger, may make it harder to consistently hit protein targets, requiring a conscious effort to include protein at every meal.
The Role of Exercise in Muscle Preservation
Protein alone isn’t enough to maintain muscle mass. To do so, you need to combine a high-protein diet with regular resistance training, such as weightlifting, bodyweight exercises, or resistance bands.
Why Resistance Training Works
Strength training stimulates muscle protein synthesis, helping rebuild and maintain muscle tissue even in a calorie deficit. Aim for 2-3 weekly sessions, targeting all major muscle groups.

FAQs About Protein and GLP-1 Medications
How much protein should I eat if I’m on GLP-1 medications?
Experts recommend 1.2 to 2.0 grams of protein per kilogram of body weight to preserve muscle while losing weight.
Can GLP-1 medications cause muscle loss?
Yes, like any weight-loss method, GLP-1 medications can lead to muscle loss if protein intake and physical activity are insufficient.
What are the best high-protein snacks?
Try Greek yogurt, hard-boiled eggs, string cheese, or a handful of nuts for quick and easy protein boosts.
Is it safe to exercise while on GLP-1 medications?
Absolutely! Strength training and regular physical activity are encouraged to prevent muscle loss and support overall health.
Can QuickMD help me plan my protein intake?
Yes! QuickMD providers offer expert advice on nutrition, including how to optimize protein intake while using GLP-1 medications.
High Protein Diets and GLP-1 Muscle Loss: Final Thoughts
A high-protein diet can be a powerful tool in preventing muscle loss during weight loss, especially for those taking GLP-1 medications. By pairing protein with resistance training and spreading intake throughout the day, you can maximize muscle preservation while achieving your health goals.
