Between the buzz at the grocery store and the headlines in our newsfeeds, it’s impossible to ignore the shift in the weight loss world right now. With more women than ever utilizing GLP-1 medications like Ozempic, Wegovy, or Mounjaro, we are seeing some incredible success stories. However, as a dietitian, I’m also seeing a significant piece of the puzzle being left out of the conversation: the impact on your muscle mass.

Whether you are using these tools to support your health journey or you’re taking the “slow and steady” root through mineral and gut support, the foundation of a healthy metabolism remains the same. If we want to feel energetic, strong, and capable of keeping up with our kids, we have to talk about protecting our muscle.

What is GLP-1 Muscle Loss?

We often focus so much on the number on the scale that we forget what that number is actually made of. Ideally, when we lose weight, we want that weight to come from fat stores. However, the latest research is showing a bit of a “whiplash” effect for those on GLP-1 medications.

Studies indicate that people on these medications often lose 25% to 40% of their total weight as lean muscle mass. Because these medications are so effective at dampening your appetite, it becomes a struggle to actually eat enough volume to support your tissues. When your body isn’t getting enough fuel… specifically protein… it starts to break down its own muscle to keep things running.

Why Muscle Matters for Moms

Muscle isn’t just about looking “toned” at the pool; it is your body’s metabolic engine. Losing it comes with a few “un-fun” side effects:

• Metabolic Slowdown: Less muscle means your body burns fewer calories at rest.
• The Fatigue Factor: Losing muscle leads to physical weakness and that “dragging” feeling by 2:00 PM.
• Bone Health: Muscle pulls on bone, keeping it strong. Without it, our long-term bone density is at risk.
• The Rebound: It makes it significantly harder to maintain your progress if or when you decide to stop the medication.

The New Protein Standard

A 2026 study found that while the majority of GLP-1 users are trying to eat more protein, less than half are hitting the minimum amount needed to protect their muscle.

The science is now showing that if you are on a GLP-1, you actually need nearly double the old protein recommendations we grew up with. To keep your metabolism and bones safe, the goal is now roughly 1.6 to 2.3 grams of protein per kilogram of lean body mass.

How to Calculate Your Daily Protein Goal

Don’t worry, you don’t need a clinical calculator. Here is the simple math to find your range:

1. Find your weight in kilograms: Take your current weight in pounds and divide it by 2.2. (Example: 150 lbs / 2.2 = 68 kg).

2. Find your minimum: Multiply that kilogram number by 1.6.

3. Find your optimal high end: Multiply your kilogram number by 2.3.

Using that 150 lb example, the goal range would be roughly 109 to 156 grams of protein per day.

Practical Ways to Protect Your Muscle

Knowing the number is one thing; hitting it when you aren’t feeling particularly hungry is another. Here is how to make it realistic:

• Prioritize Protein First: Even if you can only manage a few bites of a meal, make those bites the protein source (chicken, steak, eggs, or tofu).
• Focus on High-Quality Staples: Keep Greek yogurt, hard-boiled eggs, or lean deli meats on hand for quick snacks.
• Don’t Ignore Minerals: Minerals act as the spark plugs for your body. They help you actually use the nutrients you’re consuming.
• Watch for Fiber: Next I’ll be diving deep into why fiber is the “other half” of this battle to keep your digestion moving and your gut happy!
