Losing weight very quickly is never a good idea though because your body is more than likely eating it's muscle since it is easier to breakdown than fat is.
A pound of fat is about 3600 calories so you would have to work extremely hard just to burn off a pound of fat per day. It would take probably 4 hours of cardio minimum to do that and that is without eating anything. Never sacrifice your muscle mass to lose weight.
Not in the first few weeks back to lifting after a layoff. Building muscle will add weight until you reach your level to where it actually starts to help burn. You hold water as well. Yeah, I know all of this stuff. I am losing 1.5-2lbs per week so far. Diet is key there regardless of training. I don't rely on cardio or necessarily burning a certain amount of calories to lose. I just run because I enjoy it. I lose the weight through diet regardless of the training. I've been doing it for quite a while. If I've had a layoff from lifting for a while and come back, I will weigh heavier weekly after lifting for the first...ehh...month or so. Then it seems to not bother me so much.
I don't do excess cardio. I generally don't run or walk over 45 minutes. Usually you are pretty good to go on 5k distance. It's the longer state cardio that hurts muscle.I can maintain muscle no problem. You are right, losing weight very quickly is not a good idea NORMALLY!!! But for 1000.00 to the winner, I will do whatever it takes for 10 weeks...haha! I can put the muscle back easy. As a matter of fact, my game plan for this contest (and this is just for the contest) was losing a max of 2lbs a week, not counting water weight. Then the day before the final weigh in, I will do a semi weight cut somewhat to how the mma fighters do. A few salt baths, and some sauna work and then weigh in.
Now with that being said, I do normally lift while doing this but usually at higher rep ranges...basically just getting in some work without getting heavy.
Good info though
