Guidelines to Prevent Muscle Loss While Reducing Body Fat

Loss of muscle mass can occur naturally after age 40, but it may also result from insufficient protein, overly strict diets, excessive cardio or strength training, and prolonged inactivity. Warning signs include reduced grip strength, increased fatigue, difficulty performing everyday tasks, rapid weight loss beyond expectations, and mood changes.

Trainer Paul Lucín advises a modest calorie deficit combined with at least three to four hours of strength training per week to preserve muscle while losing fat. He emphasizes adequate protein intake, balanced meals with fruits and vegetables, simple nutrition strategies during busy periods, and consistent training to avoid the pitfalls of rapid weight‑loss programs that can diminish muscle and energy.

Following these recommendations can help maintain metabolic rate, support immune function, and reduce the risk of fractures and chronic fatigue associated with muscle loss.
