Sam has been jogging and strength training on a regular schedule as prescribed by an exercise physiologist, as well as following a nutritious diet plan. After a body composition assessment, he learns that while his weight is the same, he has lost body fat. What component has he most likely gained during this time

Muscle

Explanation:

During a weight loss regimen it is very important to loose body fat and gain muscle.

Muscle is a soft tissue in the body. During a weight loss regimen, a person may weigh the same after losing body fat and this is because muscle is heavier than fat but it gives the body shape and strength. Gaining muscle helps to reduce a person's overall body fat percentage. It keeps a person very fit and very flexible.
