Muscle mass loss can be caused by lack of exercise which is referred to atrophy and disease known as sarcopenia.
MalNutrition
Because the muscle cells that are in the muscles break away from the rest of the muscle cells when exercising and are brought back together when protein is taken in. This causes muscle mass to increase
When you do excessive work, your muscles can become strained beyond their limits. This causes very tiny tears in the muscle tissues. (This is why you feel sore after a workout.) When your body is given time to heal, the torn tissue is mended with more muscle tissue. This is what causes an increase in muscle mass.
Weightlessness causes the bones to soften and muscle mass to reduce.
myostatin-related muscle hypertrophy which increases muscle mass while lowering body fat. This rare condition is also called myotonic hypertrophy
The difference between muscle mass and muscle hypertrophy is that muscle hypertrophy is the increase in size of skeletal muscle while muscle mass is the weight of your body muscle.
an extra adjective that's not needed to describe muscle mass. Muscle mass is the amount of muscle in ones body as a % of their total weight.
It would have to be leg and muscle mass that is the answer on a+
If you were to lose only muscle mass, your total weight would decrease, but your body fat percentage would increase, as you'd be a greater percent body fat.
If you were anorexic, you probably lost a lot of muscle mass. It will take you a while to build back muscle and muscle is where you burn calories. Try building muscle mass. Eat plenty of calories and specifically 60 to 80 protein grams or more and exercise to build back muscle mass. You really need to get healthy again and you'll only do that by building muscle.
As fat is lost, you should be replacing it with muscle. Muscle is more dense, so while the size decreases as you convert fat to muscle, the mass should stay about the same. Hence, losing inches in size is far better than losing kilograms in mass.
Yes, because as the size of your muscle increases, the mass of your muscle increases. And when the mass of your muscle increases, so does the weight.
