Confused...

Options
Is the information in this all wrong?

http://chrispowell.com/all-about-calories/

I thought we shouldn't eat under our BMR as its dangerous. Using the formula in that web page my BMR is calculated differently than a different online calculator... (using this calculator my BMR is 2040).

Using a different online calculator:

http://thefastdiet.co.uk/how-many-calories-on-a-non-fast-day/

My BMR is 1450 and my TDEE is 1994 (I tend to believe these results more...).

I am now confused as to how much I should be eating to lose 1lb a week? I have been sticking to 1320 calories which works (slowly) even though this is under my BMR of 1450.

Any help appreciated...

    That's not the case.

    If you're overweight you supply the calorie deficit from your fat stores, the more overweight the more you can supply.

    If you set MFP for sedentary and 1 lb/week weight loss you will get a calorie allowance below your BMR (which goes up with logged exercise).

    Eat under your TDEE to lose weight. To lose a pound of fat, your need a deficit of 3500 calories. That translates to 500 calories a day deficit.

    If you check your TDEE/BMR on different sites, you should be getting similar numbers. In my case I think there is anywhere from 10-50 difference.

    There is only a 46 calorie difference in yours (2040, 1994). So you could bump your intake up a bit in either case.

    Yes its incorrect, it should say if you eat below your TDEE, which is BMR + activity...

    If you eat 10-15% below your TDEE you will loose weight without too much of a problem.

    A good TDEE calculator is found here, it allows you to better match your activity that a lot of the other sites:

    It also said you shouldn't use exercise calories as permission to eat more food

    Thanks for the replies. So if I continue to eat 500 calories below my TDEE I should lose weight?

    Yes, but remember to recalculate the TDEE number as you lose weight. As your weight decreases, so does your BMR, less mass to keep alive, hence you will gradually need to reduce the calories going in to maintain the deficit level
