Preserving Muscle While Using GLP-1 Medications for Weight Loss

As the use of GLP-1 medications like Ozempic, Wegovy, and Zepbound rises among Americans, there is increasing emphasis on protecting muscle while losing weight. Gallup reports that 11% of U.S. adults now use these drugs for weight loss, up from 3% in 2024. Research indicates that a significant portion of weight lost through these treatments is lean mass, which includes muscle and other tissues.

Importance of Lean Muscle Preservation

Gary Brecka, a biologist and longevity expert in Miami, stresses the need for preserving lean muscle during GLP-1 treatment. He warns that weight loss with these medications is not purely fat loss. Instead, about 20% to 40% of the weight lost comprises lean body mass, which includes muscle, water, organs, and connective tissues.

Exercise and Muscle Maintenance

Brecka advises that simple exercise strategies can help maintain muscle mass. He suggests starting with just six minutes of resistance exercise each day. This approach helps counteract muscle loss without requiring long gym sessions. Simple exercises such as body-weight squats, planks, and dumbbell workouts can be effective.

Incorporating Exercise into Daily Life

Brecka encourages people to integrate exercise into daily routines. For instance, walking with a weighted vest or choosing stairs over escalators can enhance physical activity. He emphasizes making exercise a daily, non-negotiable habit, recommending at least three days of resistance and cardiovascular training weekly.

The Role of Protein in Diet

Protein is crucial for supporting muscle and other tissues like tendons and ligaments. Brecka highlights the importance of consuming adequate protein, whether from animal or plant sources, to supply necessary amino acids for muscle maintenance. Current guidelines suggest consuming 1.2 to 1.6 grams of protein per kilogram of body weight daily.

Brecka also advises monitoring any decline in energy or physical performance, such as struggling with previously easy tasks, and discussing these with a healthcare provider to tailor the treatment effectively.
