BMR and TDEE

paulahunter3

I am trying to work this out and am getting various results;

BMR on Mifflin St Jeor is 1292
Harris is 1406

TDEE Calculated is 1688

I am utterly confused as to which one I should be sticking to?

I am looking at doing the 5 2 Fasting Plan and don't know what I should be eating on a normal day.

I am only looking for help in this thread so please no *****y, nasty comments.

As my gran would always say if you don't have anything nice to say then say nothing at all

There's a post on here somewhere by DarrelBirkett al about BMR/TDEE, have a look for that and it should help!

You're supposed to eat -20% of your TDEE.

If your TDEE is 1688, then you should be eating somewhere along the lines of between 1300-1400.

You're supposed to eat -20% of your TDEE.

^ this for weight loss and never, ever below your BMR. Stay between BMR and TDEE and you'll be fine.

I prefer the Katch-McArdle forumla, but it requires you to know your body fat percentage.

The Katch-McArdle Formula (BMR):

P = 370 + \left( {21.6 \cdot LBM} \right), where LBM is the lean body mass in kg.

Each formula will give you a slightly different answer. Best bet is pick one and stick with it.

You should be eating between BMR and TDEE for weight loss. Do not consistently eat below BMR, once in a while is fine. We all have those days we just aren't very hungry or are feeling ill.

Most people will eat TDEE - 20%, but this isn't set in stone. Your reduction percentage is personal preference. Find a reduction you can live with and stick with, that is the important part. If that means your reduction is only 10%, so be it. It may mean less weight loss week over week, but in the long run is you stay with it.

I love http://scoobysworkshop.com/accurate-calorie-calculator/. It lets you adjust the reduction and also add a calibration. Weight loss is not the same for everyone. Read the instructions on its use, its a great calculator.
