How to Preserve Lean Muscle Mass During GLP 1 Medical Weight Loss

How to Preserve Lean Muscle Mass During GLP 1 Medical Weight Loss 

GLP-1 medications are a highly effective weight loss tool that complements a healthy lifestyle. They help you reach your goals with less hunger and fewer junk-food cravings. 

But if you’re not careful, muscle mass can disappear almost as quickly as body fat. Muscle matters because it helps maintain strength, boost metabolism, improve definition, and support long-term well-being.

The good news is that you don’t have to sacrifice muscle to reach your weight loss goals. With the right combination of protein, strength training, and smart nutrition strategies, you can protect your hard-earned muscle when shedding unwanted pounds. 

Visit with Marc Gittleman, MD, FACS, or Amy Gittelman, MS, APRN, BC, at Optimal Health Miami in Aventura, Florida, for a personalized GLP-1 weight loss treatment plan.

6 ways to preserve lean muscle during GLP-1 weight loss

Here are six simple ways to maximize muscle during your weight loss journey:

1. Eat protein first

Consider beginning each meal by eating protein-rich foods, such as:

  • Fish
  • Chicken
  • Seafood
  • Lean red meat
  • Eggs
  • Tofu
  • Beans
  • Greek yogurt
  • Cottage cheese

Protein helps your body maintain muscle, even when your appetite is low. Aim for about 20-30 grams of protein at mealtime.

2. Try protein shakes

If you’re not craving protein-rich foods, try drinking your protein by adding a shake with at least 20 grams of protein. Protein shakes help you get enough protein when your appetite is low, supporting muscle maintenance while shedding pounds.  

3. Don’t neglect the other food groups

Fruits, vegetables, whole grains, and healthy fats also play an important role in maintaining optimal health during GLP-1 weight loss. Examples of nutritious plant fats include nuts, seeds, nut butter, avocado oil, olive oil, and avocados.

Filling more of your plate with fruits, vegetables, whole grains, and legumes is a simple way to add more fiber and nutrients, and research has linked healthier plant-based eating patterns with a lower risk of several chronic diseases.

4. Eat smaller, more frequent meals

During GLP-1 weight loss, eating smaller, more frequent meals helps keep your body steadily fueled and maintain muscle. This may also reduce side effects sometimes caused by GLP-1s. You might eat a small meal or snack about every few hours guided by your body’s hunger cues.

5. Track your cardio

Cardiovascular exercise can optimize heart health and keep you fit during your weight loss journey. Aim to gradually increase aerobic workouts to 150 minutes weekly, up to 30-60 minutes daily, to achieve and maintain your goal weight. Consider brisk walking, jogging, cycling, swimming, or using a rowing or elliptical machine. 

6. Focus on strength training

Strength training is your best friend during GLP-1 weight loss. Adding it to your weekly routine is vital to preserve lean muscle mass. Aim to strength train (weightlifting or use your body weight or bands as resistance) at least 2-3 days weekly for 30 minutes per session.
