Do I eat my BMR or below it?

BMR means Basal Metabolic Rate. This is the amount of calories just to keep your organs functioning if you laid in bed all day. You need that amount of calories to live, plus more calories to fuel any activity like getting out of bed and walking around and going to your desk job. TDEE is Total Daily Energy Expenditure. The amount you need to fuel you based on how active you are. Also called "Maintenance", the amount you need to stay the same weight and not gain or lose. Eat less than that number, but more than BMR.

^^^^For The Win^^^^

Erm... how do you know what your BMR & TDEE are? :S

I eat my BMR right now but I just started the Spike diet so that is part of my plan. I'll have one day a week where I eat twice BMR and the rest stay between 1200 and BMR (and not eat exercise calories back). I almost never stay at 1200 though...ok, I never do.

eat what mfp tells you too.

Also you can eat below your BMR if you're overweight, but you dont need to to lose weight, just need to eat below maintenance

MFP set me to 1200 calories because I told it I wanted to lose 2 pounds a week. That was not enough because my REAL BMR is about 1400, the amount for my body to function properly without moving out of bed even. It is really distressing to me that people don't have all the information they need when setting up their goals to make informed choices unless they do some more research. Initially I did lose some weight eating 1200, but then it stopped.

Google BMR and TDEE calculators. There are a lot of them out there.

My BMR is like 1900, how is it that I should eat more than that? That already seems like a lot.

I'm just so frustrated.

Please go to Google and use a BMR calculator NOT on this site. Then look up TDEE calculator. I explained in the post above what BMR and TDEE means. This website uses the terms interchangeably and that is where a lot of people have trouble.

For safe weight loss you should eat 20% less than TDEE.

So if your TDEE is 2500, then you would want to eat 20 % which = 500 calories less than that.

You can eat below your BMR! You're not going to die eating below your BMR, your body makes up the calories by burning fat for fuel, just as it does for other activities. The whole point is to create a deficit, and that is one way to do that. When i weighed over 200 lb, it was perfectly safe for me to aim for 2lb a week loss, if I'd only eaten at my BMR I would have lost less than 1lb a week...

Then you will hear around here the debate about "should I eat my exercise calories back".

If you use MFP settings, then YES because MFP calculates you for the calorie deficit so that you will lose weight without exercising. You will end up with too large of a calorie deficit than is healthy if you don't eat them back.

If you do your own calculations and eat 20% less than TDEE, then NO if you do moderate exercise, but perhaps eat back some on heavy exercise days.

Your body needs fuel in order to not lose muscle mass.

My BMR is around 1500, MFP was setting me at 1200 just to lose a lb, (I am short).

Waaaay too low.

So I have switched to eating between BMR and TDEE, only just started so won't know results for a bit.
I epect a gain the first week as my body gets used to the extra, but at least I won't feel lightheaded anymore.

ahhh thank you. this is what I've been trying to find an answer for - it's what I THOUGHT but I just wanted someone else to say it

I goggled TBEE and BMR and came up with 1475 calories per day to lose 2 pounds a week. Around 1949 to lose 1 pound a week. Using the BMR on MFP I came up with 1362 per day. A big enough difference but not as big as I thought it might be after reading comments here. My issue is I have a hard time eating that much HEALTHY food! Veggies do not have a lot of calories and I'm trying to watch my carbohydrates. I want the excess weight off ASAP so I am shooting for the 2 pounds a week. How will I ever eat 2549 healthy calories to maintain???? That is a lot of food if we are eating fresh, natural, no processed foods...

OK so when I'm tracking my daily intake on here how do i change my 'limit' from 1200 to what it should be. I dont want it to read as a deficit every day/

Thank you!

The problem is that any calculator can only estimate these numbers based on things like hight and weight. If you want an accurate number you need a proper body stat analysis with calipers etc. Ask your doctor or google for a local place that will do this. I had mine done and it turned out my real BMR was lower than MFP thought by 200+ calories.

A decent HRM strap can help on the exercise front too. Again, I found out mine estimates were way out after buying a polar HRM with chest strap (only cost £35 and well worth it for the useful info)
