you can do it.
people underestimate the human body.
the key thing is your cardio in the morning. this is where you will be burning the fat you will lose. you can stillmaintain, even build muscle while dieting; what you have to do is be perfect on your diet.
there is no way you will lose muscle if you are taking in enough protein, and are working out every day. keep your carbs intake to just prior to, and just after weight training. get enough grams of carbs in your sytem to just make it through a workout, then consume a small amount of simple carbs immidietly after you workout. other than that keep it at zero.
its best to wake up early...take your eca stack with some l glutamine, and get in 1 to 2 hours of cardio. , then eat a meal and hit the gym as soon as its digested. the post workout carb will go to replenish muscle glycogen, and your pre workout carbs will have been used up. so for the rest of the day you should be in ketosis; but that doesnt mean eat like you on a low carb diet...you should not eat ANY fats other than fish oil supplements, which you should have with every meal. get in 40-50 grams of protein at least every two hours...at night before youg o to sleep do 30 mins to an hour of slow paced cardio, drink some l glutamine, and go to sleep.
there is absolutely no reason why you cant build muscle and lose fat over the course of two months.
