The muscle you build stays with you, and it's strong and solid as long as you continue to keep up your exercise and eat right. Now if you decide to workout 2 hours a day and only eat a 3 crackers for you whole intake of food that day. Yes your body will eat the muscle your building, but then after a few days of that, you won't be getting out of bed, and you'll feel really really weak. Not to mention really hungry.
But your body will hit the carbs first, and then the fat, just make sure your calorie intake is high enough that it will hit both the carbs and the fat. As the funny thing about our bodies, is if you don't eat enough, it will slow down and then start saving. Which then turns to more fat. If your trying to lose weight, eat as often as possible, but keep it good and healthy and watch the calories. But if you can fuel your body every 3 to 4 hours while your up and moving, you'll keep it pumped up and burning both crabs and fat. Provided what your sticking in your mouth isn't junk. And you don't need a whole meal every 3 to 4 hours, but just 1/2 a serving or so. I know some people really do like to have a real sit down meal 3 times a day and if your one go with a 1/4 or 1/2 a serving of fruit or veggies for your inbetween meals, meal. If your like me, and like to eat all day long and don't like to actually have to sit down and eat 3 or 4 things at once, divide the meal up so you eat 1/4 of it about every hour. Since I like to snack in front of the computer and since my computer is my work. I simply just divide my meals up so I can eat them while I work, so I don't get any extra snacks. And I don't have to take a break for lunch or whatever, as it's being taken care of as I type and do other things. One thing I did notice doing this, was my motablism really seemed to speed up and when I exercised I had a lot more energy.
