Preserve Muscle During Weight Loss

Successful weight loss is not simply about becoming lighter. It is about improving your body composition.

Preserving muscle while reducing body fat leads to better long-term health, better physical function and more sustainable results.

Unfortunately, muscle loss is common when people rely only on calorie restriction.

Why Muscle Matters

Muscle supports movement, strength, balance, metabolism and healthy ageing.

Maintaining muscle also helps improve everyday function and reduces the risk of injury as we get older.

How Muscle Is Lost

Large calorie deficits, inadequate protein intake and little or no resistance training increase the risk of losing muscle during weight loss.

The body responds to the demands placed upon it. Without a reason to keep muscle, it becomes easier to lose it.

How To Preserve Muscle

Strength training provides the stimulus for muscle maintenance, while adequate protein provides the nutrients required to support recovery and repair.

Together they create the foundation for healthier weight loss.

Measure What Matters

Body composition provides much better feedback than body weight alone.

Body composition scanning helps determine whether weight loss is coming primarily from fat while lean muscle is being preserved.
