Why do men over 40 start to lose muscle and gain fat.

• Men over 40 start to lose muscle and gain fat largely due to sarcopenia, the natural age-related decline in muscle mass.

• Testosterone and growth hormone levels gradually drop, reducing the body’s ability to build and maintain muscle.

• Metabolism slows, so the body burns fewer calories at rest.

• Combined with lower activity levels, this leads to increased fat gain and reduced strength over time.

How can Core Nutrition & Fitness help

• By designing individual nutritional plans that provides enough protein to slow or reverse sarcopenia and support muscle repair.

• Balances calories and macros to reduce fat gain while maintaining lean mass.

• Optimizes nutrient timing to improve energy, recovery, and training performance.

• Ensures adequate micronutrients (vitamin D, omega-3s, magnesium) that support hormones, metabolism, and healthy aging.
  

What type of fitness training will be required

• Resistance training (weights or machines) is the most effective for rebuilding muscle and combating sarcopenia.

• Progressive overload—gradually increasing weight, reps, or intensity—stimulates consistent muscle growth.

• High-intensity interval training (HIIT) boosts metabolism and helps reduce body fat efficiently.

• Mobility and core work support joint health, stability, and long-term performance as men age.

• All fitness plans will be designed for the individual there is no one size fits all with Core Nutrition & Fitness
