Obesity rates in the U.S. continue to climb, with more than a third of adults now considered obese. Traditionally, Body Mass Index (BMI) has been used to assess health, but BMI is limited because it doesn’t distinguish between fat mass, muscle mass, water, or bone.

The InBody Body Composition Analysis offers a far more accurate picture of health by measuring body fat percentage, skeletal muscle mass, and visceral fat. Knowing what your body is truly made of guides more effective nutrition and exercise plans.

Studies show that different types of training affect body composition in unique ways. Bodybuilding-style training can significantly reduce fat while improving lean mass, while High Intensity Interval Training (HIIT) excels at fat reduction and cardiovascular improvements.

Improving body composition requires attention to four key areas:

  1. Nutrition – Choose a diet that supports lean mass and fat loss, such as a modified Mediterranean, Paleo, or Ketogenic plan.

  2. Resistance Training – Strength training stimulates muscle repair and growth, especially under the guidance of a qualified trainer.

  3. Hormones – Growth hormone (GH), testosterone, and IGF-1 rise after training and play essential roles in muscle development.

  4. Sleep – Deep sleep (NREM Stage 3) is when most growth hormone is released. Poor sleep raises cortisol, reduces testosterone, and slows progress.

Body composition change is a long-term lifestyle shift—not a quick fix. With proper nutrition, training, and rest, lasting improvements in health and fitness are achievable.
