80. Muscle will turn to fat after stopping a weight training

True

False

This statement is false. Muscle and fat are two different types of tissue and cannot directly convert into each other. When a person stops weight training, their muscles may decrease in size and strength due to lack of exercise, but they do not turn into fat. However, if a person stops exercising and continues to consume the same amount of calories, they may gain fat because they are not burning as many calories as they were before. This can give the appearance of muscle turning into fat, but it is actually a result of fat gain and muscle loss.
