Weight loss journeys often focus on the number on the scale. Yet, this number alone does not tell the full story. When using GLP-1 medications such as Ozempic, Mounjaro and Wegovy which are increasingly popular for weight management, understanding changes in body composition becomes even more critical.
Research shows that 40% of weight loss with GLP-1's can be muscle rather than just fat, which may affect overall health and metabolism. Body composition scanning offers a clearer picture of what is happening inside the body, helping to guide safer and more effective weight loss.
What Is Body Composition Scanning?
Body composition scanning measures the proportions of fat, muscle, and water in the body. Unlike a simple scale, which only shows total weight, this scan reveals how much of that weight comes from fat versus lean tissue. We use the Seca mBCA 554 which is radiation free, quick and accurate.
Understanding these components helps tailor weight loss strategies to preserve muscle and improve overall health. Our Exercise Physiologist and Naturopath Doctor will go over the results with you to ensure you are on the correct weight-loss plan.
Why Muscle Loss Matters During Weight Loss
Muscle plays a vital role in metabolism, strength, and daily function. Losing muscle during weight loss can slow metabolism, reduce strength, and increase the risk of injury. This is especially important when using GLP-1 medications, which can suppress appetite and lead to reduced calorie intake, sometimes causing unintended muscle loss.
Maintaining muscle mass supports:
Higher resting metabolic rate
Better physical performance
Improved insulin sensitivity
Long-term weight maintenance
Without monitoring body composition, muscle loss can go unnoticed, potentially undermining the benefits of weight loss.
How GLP-1 Medications Affect Body Composition
GLP-1 receptor agonists, such as semaglutide helps reduce appetite and improve blood sugar control. They have shown significant success in promoting fat loss. However, research indicates these medications may also contribute to muscle loss if not managed carefully.
A study published in Obesity journal found that patients on GLP-1 therapy lost both fat and lean mass, highlighting the need for strategies to protect muscle during treatment. This makes body composition scanning a valuable tool to track these changes and adjust nutrition and exercise plans accordingly.
Using Body Composition Scanning to Guide Your Weight Loss Journey
Regular body composition scans provide actionable insights:
Track fat loss versus muscle loss
Adjust diet to include enough protein
Modify exercise to include resistance training
Monitor hydration status
Evaluate progress beyond the scale
For example, if scans show a drop in muscle mass, increasing protein intake and adding strength training can help preserve lean tissue. If fat loss stalls but muscle remains stable, it may indicate a need to adjust calorie intake or activity levels.
Tips from our experts:
Prioritize protein
Aim for 1.2 to 2.0 grams of protein per kilogram of body weight daily to support muscle repair and growth.
Incorporate resistance training
Exercises like weight lifting, bodyweight movements, or resistance bands help maintain and build muscle.
Stay hydrated
Proper hydration supports muscle function and accurate body composition readings.
Schedule regular scans
Every 4 to 8 weeks can provide timely feedback on how your body is responding.
Work with healthcare professionals
Dietitians, trainers, and doctors can help interpret scan results and tailor your plan.
What to Expect During an Advanced Body Composition Scan
The process is simple and painless:
You may stand on the Seca mBCA 554 scale
Electrodes or sensors send harmless signals through the body
The machine calculates fat, muscle, and water percentages effortlessly
Results are usually available immediately, and you will have access to your results online to review
Dexa Scan vs. Seca mBCA 554 what's the difference?
Dexa measures your bone density, and the Seca mBCA554 (Medical Body Composition Analyzer) does not. The Seca is radiation free and provides results on muscle and fat mass. Your results can be accessed online or in the app, and you can compare each report easily every 3 months to see the changes.
