GLP-1s: Protecting Muscle and Bone While the Scale Drops

One of the biggest things I talk about with clients taking GLP-1 medications is that losing weight is only part of the goal.

The scale tells us how much weight you're losing, but it doesn't tell us what that weight is made of.

During significant weight loss, some lean mass—including muscle—can be lost along with body fat. That matters because muscle helps you stay strong, active, independent, and capable of doing the things you enjoy. So our goal isn't simply to make the number on the scale smaller—we want to improve your overall body composition.

The good news is that we have some control over what happens while you lose weight. Two of our biggest tools are adequate protein and resistance training.

Protein provides the building blocks your body needs, while strength training gives your muscles a reason to stay strong.

For many clients, I recommend building toward two to three full-body strength workouts per week, focusing on major movements like squatting, hinging, pushing, pulling, lunging, and core work.

You don't need to destroy yourself in the gym. Consistent, challenging workouts that you can recover from are what matter.

Your training also needs to fit how you're feeling. GLP-1 medications can sometimes come with lower appetite, nausea, or changes in energy, particularly when you're getting started. On those days, we can reduce the volume or intensity rather than skipping exercise completely.

The goal is consistency, not perfection.

For beginners, that might mean bodyweight exercises, resistance bands, machines, or simple movements like sit-to-stands and step-ups. As you get stronger, we can gradually increase the challenge.

We're trying to help you lose body fat while maintaining your muscle, strength, bone health, and physical function.

The GLP-1 is a tool—but your nutrition, training, and daily habits are what help determine how healthy you become along the way.
