BMR and TDEE help!

[Whatsthatnoise]

Hi I have finally bitten the bullet and decided to lose weight. I am 5,10 and weigh 16stone .
I signed up to my fitness pal and it's calculating that I need 1900 calories per day, I checked my bmr and that says 1800 and my tdee is 2800. Those numbers seem really high to me. Surely if I need 1800 cals just to survive I wouldn't be fat in the first place.
Am I misunderstanding this? Will I be causing myself problems if I only eat 1200/1500 cals per day.
I have also started 30 day shred and couch to 5k, should I be eating my exercise calories back.
TIA

Can't help sorry - like you I find it hard to understand BMR and TDEE. With TDEE, it seems to be calculated on the basis of activity, so if you tell it that you are moderately active, does that mean that you can't count your exercise calories as extra, because they are already included iyswim?

For example, I exercise for IRO 500 cals on 5 occasions each week. Does that mean that on those 5 days my TDEE of 1740 is actually 2300 or is it still 1740 ? .

I'm sure someone knowledgeable will be along to explain .

Carabos your TDEE would stay at 1740, your exercise calories are already included.

Whatsthatnoise without your gender and age then I can't double check your TDEE - but a TDEE of that level would indicate you've said you're exercising a substantial amount (not implying you're not doing this, btw!), remember that TDEE is the calories you need to stay the same weight with your current level of exercise.

TDEE less 20-25% is a reasonable figure to go for, so on your calculations, average daily calorie intake of circa 2150 calories would see you losing weight -as long as you don't eat any exercise calories back.

Hi could you help me work lut what my daily intake should be

I'm 5ft 6 - 13st 11 and pretty sedentary

Thanks x

Hi treadingwater

Without age & gender it's not as accurate, but I've assumed you're female and 30

To stay the same weight you need to eat around 1940 calories per day.

To lose weight, around 1500 per day.
