The most important thing when it come to dieting is NOT to starve yourself. If you do your body will hold on to the fat and not want to let it go. Eat a lot of salads, as much as you can in fact, in this way you will not gain any extra fat and the fat you have will be burned off by the salad, be sure to eat a lot of cabbage, cabbage burns fat the best. Oh and drink a lot of water, at least a gallon a day, it washes fat away. Of course exercise is very helpful. There are two different ways you must exercise to loose weight and to gain mussel. To lose weight is described above, to gain mussel you have to eat a lot of meat, I mean a whole lot. And take protean power up to 40 gram a day. And work out hard with heavy weights. When building mussel protean is the key, when loosing weight, eating no carbohydrates and plenty of salads are the key.
