Does fat literally turn into muscle?

For example, if you have a lot of fat on your stomach and you do crunches, will the fat there become muscle or will it eventually burn off, giving you an eventually flatter stomach? Someone told me that if you weigh too much and do crunches that the fat will turn into muscle and then you will have a hard fat stomach...didn't sound right to me, please clarify. Thanks!

    Fat doesn't turn to muscle, the fat is burned off and the muscle is built up. You can build muscle and keep the same amount of fat.

    1) Fat and muscles are completely different. Fat cannot turn into muscles nor can muscles turn into fat. Muscles are composed of protein; fat is a form of glucose. You would have a better chance of turning a cup of sugar into a T-bone steak.

    2) Crunches do not help burn off fat in the abdominal area. You cannot burn fat just in the area that you exercise. What you are doing is called, targeted exercises or spot reduction which has been scientifically proven NOT TO WORK.

    3) The only way to lose the fat around your abs is to lower your overall body fat percentage. This means you need to control/limit the amount of calories you consume in a day (less than 1700) and do aerobic exercises such as walking, jogging, using an exercycle or elliptical.

    No, a fat cell will ALWAYS be a fat cell. what happens when you diet or exercise is that the fat cells lose mass and the muscle cells are able to use the energy which the fat cells once had and grow stronger and more massive themselves. So, those who said that fat turns into muscle are wrong, IF you take them to be biologically correct. However, if you take them to be analogously correct then, as Fat cells lose mass, muscle cells increase in mass and in the respect, one could say that fat turns to muscle. However understand that is only analogous and not an actual truism.

    No fat and muscle are made up of completely different things so fat doesn't turn directly into muscle. It is a myth that fat turns into muscle.

    No, fat does not *literally* turn into muscle. You have to burn off the fat (which you cannot do in an isolated area, your body burns fat all over), and you have to build muscle (which of course, you can build in a specific area).

    You will not get a "hard stomach" by working your abs if you are overweight, since your ab muscles will build UNDER your fat.

    you whole body chemical changes from working out, you start to reform muscle thats already there and to shape it and feed them with proteins and the body turns to use this fat as fuel to convert fats into energy, called living off the fat of the land, as muscle grow and fat melt you some times gain weight as muscles are so much heavier than fat,once fat deposite get small we need to learn to eat many small snack or meal rather than big bulky ones to keep the bulge down and tummy flat

    No lol that's a high myth. Muscles don't turn into fat, and vise versa. If you get fat, the muscles shrink in size, but do not turn into something else. Fat burns, like sit-ups that's why you feel that burn when doing it for awhile.

    No, that is physically impossible. Fat cells cannot become muscle cells. In fact when you are born, you cannot build any more muscle cells. You are done making them (Which is why muscle injuries are permanent, they will never heal 100%). When you build muscle MASS (it's called building muscle mass, not just building muscle) you are building more muscle fibers within the muscle cell, which make the cell larger and stronger. So this is what makes muscles bigger.

    You cannot isolate fat loss. Doing crunches doesn't cause fat loss in your stomach, in fact it doesn't' cause fat loss at all. Cardio exercise is what causes fat loss, weight lifting and body weight exercises aren't cardio. They burn calories, not fat. Just because you workout a particular body part, doesn't mean you lose body fat in that area. Your body burns body fat from certain places on your body (this is determined by genetics. We all put weight on in different areas).

    Going low carb is which can encourage weight loss. Limit the carbs (especially processed carbs like muffins and bagels) you need to include a little fat.
