how long till I see results? will I lose much weight?

Eating 1000 calories per day and then exercising off 800 is in no way healthy. You're going to end up being very ill doing this.

I have been working out for a little over a week straight and am loving it! Every session I burn just shy of 800 calories. I only eat 1000 calories a day already. I weigh 195? So how long would you estimate I see changes? And how long do you think it'd take to lose 20 pounds?

Are you eating 1000 and burning the 800, and not eating back any of those exercise cals? :noway:

This is not the way to use My Fitness Pal.

First of all, you should be eating more than 1000 calories no matter what. The bare minimum recommendation for women is 1200, and even that it too low for most of us. Goal means GOAL - something you are aiming for, trying to achieve - not a mark to fall well short of.

Second, the daily goal you're given here at MFO P already has you at a deficit - meaning you could eat to goal every day, do zero exercise, and you'll lose weight. Burning off more calories through exercise creates a much larger deficit, too large, and can cause you all sorts of problems in the long run. This is why the cals burned from exercise are added back into your goal - you daily NET cals should be at or very near goal.

Lastly - what sort of exercise are you doing and how are you determining the calorie burn? 800 is a fairly high burn, and MFP's estimates for exercise burns are notoriously high, as are fitness machines. You may be burning less than you think.

The MFP system works great, but only when used correctly. Make sure you have entered your info accurately and your goals realistically (as in if you don't have 75-100lbs to lose, your weekly loss goal should NOT be 2lbs a week). Then eat your calories (all of them!), drink water, do some exercise, take rest days, get good sleep. And have patience. Take some progress photos for comparisons along the way, and track your measurements as well as your weight.

But don't sell yourself short by under eating and/or over training. This combination leads to failure - not mention a risk of major health problems if you try to do it for too long.

Good luck!

Troll much?

Please eat! You are only netting 200 calories! That is seriously Dangerous!

Stop feeding the troll, his account is disconnected.

To answer your question, you will most likely not see any results at all, so the time frame won't really matter.
