One day : 1105 calories eaten - 2000 calories burned...?

If I burn 2000 calories in the gym (treadmill & eliptical + a little weights) M-F and only eat 1105 healthy cal. every day how much weight will I lose in two months?

Ummm 2000 cals / workout session means you must be exercising 2 - 3 hrs at HIGH intensity / day. Or do you mean 2000 cals burned / week ?

And what's your BMR? It's all simple math, either way. A 3500 calorie deficit = 1 pound.

Not as much as you're thinking - your body will think you're starving and slash your metabolism in an act of self-preservation. Plus, behaviorally, you'll end up bingeing your head off in about a week.

1105? What a strange number. Where did you come up with that?

Yes, you wouldn't be eating enough calories, even without the exercise. If you are going to exercise so much (which probably is not healthy), you would even need to eat more than 1200 calories.

Life is not the Biggest Loser, and remember - they are under medical supervision, and I think the Biggest Loser book advocates very low calories, which is not responsible in my opinion (just browsed through it at CostCo). Also remember, that not all those Biggest Loser contestants have kept the weight off.

DON"T DO IT! You'll screw up your metabolism.

Also, how could you possibly burn 7000 calories in 1 day from working out?

The other thing is that during the biggest loser, if you notice, you will see the trainers admonishing the people who don't eat ENOUGH calories as much as they talk to those who eat TOO MUCH....

If you go at that pace, You'll find yourself exhausted after only a few days--you need to refuel immediately after exercise (not with a meal, but with a small snack)--which helps to replenish your glycogen stores... otherwise, the next day, you'll just feel like someone ran you over with a steam roller.

Binge exercising is nearly as bad as binging with food. Neither are healthy and eventually, you'll self-destruct...

OP here

?Why 1105 cal. - b/c I eat basically the same thing every day except for dinner
?How 2000 cal. burned per day - run 4.5 miles + weights in am; eliptical very hard for 1 hr at lunch - that's what the machines say I am burning and I put in my #s
?BMR = about 1900 +/-
? "You will binge / burn out" I don't think so, I have been slowly working up to this excersise and down to these calories over 18 months so far I have done the above for 1 week

Will I really not lose weight??

You can't really believe what the cardio machine reads. I put on my heart rate monitor which is very accurate and set the treadmill. The treadmill said that I burned 300 calories more than my heart rate monitor. They can be off by quite a bit. I would suggest to invest in a heart rate monitor. There is a strap that goes just under your breasts which measures your heart rate and sends the information to a watch. Gives you you're workout length, amount of calories burned, average heart rate, minimum heart rate and maximum heart rate for during your workout.
