i have a very skinny body type with almost no fat, if i burn to many calories will my body start eating away at the muscle?:think
not if you eat enough before hand and make sure you get some carbs to restore glycogen stores and protein for muscles afterwards
By the time that happens you will be feeling pretty damn lousy. It is common sense to start out slow but try to improve a little bit every week. Don't worry, in six months you will be the toughest guy in town!
unless your a cruiseriweght evander holyfield you aimnt goign to burn into your muscle. if your keeping fit then your body will look after itself. you will lose fat from all over the body...every where all those nooks and crannies fat is stored. you will be burning you muscle away if you train and eat little meat/protien.
There are site that you can google to get your BMR and figure the calorie intake you need to gain weight. Just make sure to take in good sources of protien, carbs and healthy fats. Eat alot, since your skinny, eat just before you go to bed.
