This is called "body recomposition" by scientists and fitness professionals—in other words, the process of changing the composition of your body by lowering body fat mass and increasing muscle mass.
Muscle hypertrophy or muscle building involves a hypertrophy or increase in size of skeletal muscle through a growth in size of its component cells. Two factors contribute to hypertrophy: sarcoplasmic hypertrophy, which focuses more on increased muscle glycogen storage; and myofibrillar hypertrophy, which focuses more on increased myofibril ...
The attempt to increase muscle mass in one's body without any gain in fat is called clean bulking. Competitive bodybuilders focus their efforts to achieve a peak appearance during a brief "competition season". [53] Clean bulking takes longer and is a more refined approach to achieving the body fat and muscle mass percentage a person is looking for.
During compensation, animals may experience changes in food intake, body composition (increased fat and lessened muscle), metabolism, and the endocrine system. [26] Animals undergoing compensatory growth have been seen to have impaired muscle development after regrowth, which leads to impairments in locomotion and escape movements. [14]
3. Your body fat percentage isn't budging. If you're losing weight but your body fat percentage is staying the same, it's probably a sign you're losing muscle. "Your body won’t shape the way you ...
A man with a busy office job made his gym routine more efficient with full-body supersets. The workouts helped him build muscle and burn fat in four months after years of not seeing results.
A wide variety of body composition measurement methods exist. The gold standard measurement technique for the 4-compartment model consists of a weight measurement, body density measurement using hydrostatic weighing or air displacement plethysmography, total body water calculation using isotope dilution analysis, and mineral content measurement by dual-energy X-ray absorptiometry (DEXA).

The hallmark sign of sarcopenia is loss of lean muscle mass, or muscle atrophy. The change in body composition may be difficult to detect due to obesity, changes in fat mass, or edema. Changes in weight, limb or waist circumference are not reliable indicators of muscle mass changes.
