No. You can loose muscle by poor diet, but excercise increases muscle.
Yes, exercise is the key to keeping muscle tone. If you lose weight and don't exercise you will also lose your muscle in the process.
Lack of physical exercise can result in loss of: muscle mass, bone density, flexibility, energy level, mood, immune system, and heart health. It can also cause muscle atrophy and weight gain.
dehydration and muscle loss
No, Weight loss does not cause muscle loss. Weight loss and muscle loss is little bit different. Typically, when you want to “lose weight,” you mean you want to lose fat while maintaining as much muscle as possible. If you’re losing muscle and not fat, then you may need to make some changes to your diet and exercise to counteract this.
Disuse atrophy is degeneration and loss of muscle mass. The size, shape, tone, and strength of muscles (including the heart) are maintained with mild exercise and increased with strenuous exercise. Promoting exercise to maintain a patient's muscle tone, joint mobility, and cardiovascular function is an important nursing function.
It's probably possible to grow muscle on any diet that contains the elements necessary for growth. Exercise vigorously, and growth will happen.
Depends. At first, muscle exerice tends to promote muscle development, and muscles have weight to them. But more muscles means you can burn more calories when exercising, and more burn can help with weight loss.
Weight loss is A LOT more about diet than exercise. The most probable reason is that when you exercise you get hungrier and eat more than you should. Possible, but less probable, is that exercise does promote muscle growth. If you're actually skinny to start with, then exercise can build enough muscle to cause a noticeable weight gain. This is why it's not that smart to look at weight alone. One should try to back it up with checking your size(if your waist is shrinking but your thighs are growing you're most probably losing fat and gaining muscle), or fat/muscle ratio.
This is rarely possible. Building muscle causes weight gain, so this offsets weigh loss from losing fat. However exercise is always a good thing. Something as simple as taking the stairs or parking a little further away when going to the store will get you some extra exercise without making time to go to the gym.
Muscle cannot turn into fat, because one tissue cannot evolve into another. What does happen is that a loss in activity results in the shrinking of muscle mass because of disuse. Also, fat levels may increase because a loss of activity may result in a surplus of calories, which can result in an increase in fat. So, after not working the body for a while, muscles may shrink and fat may increase and can result in looking less firm (loss of muscle) and more flabby (increase in fat).

Muscle Atrophy is the technical name for loss of muscle mass due to disuse, starvation, or disease.
