Excercise Calories

Do I eat them back? 5'7 320 lbs. 1,700 Calories puts me at 1,000 cal deficit. Since I'm bigger, I can reasonably lose more at first. Should I workout maybe an additional 500 a day And NOT eat them back? BMR is 2,200. 2,700 TDEE.

thank you.

    320 lbs ? it doesn't matter if you don't eat back your estimated exercise calories IMHO.

    Well, exercising would increase your TDEE. So if your TDEE without exercise is 2700 and you burn 500 with exercise, than your TDEE with exercise is 3200.

    Safe weight loss is typically no more than 2lbs per week (1000 calorie deficit per day) or I think 1% of body weight (can't remember) unless you are under a doctors supervision (in which case you would want to follow your doctor's recommendations).

    Okay, so I would subtract 1,000 from 3,200( if I've worked out) and then eat the remaining 2,200? I would still be losing 2 lb a week? Sorry for all the questions. This REALLY has me so dang confused.

    As you have quite a lot to lose, personally, I would use them as a buffer so to speak. Sort of a top end of the range - for days where you are hungrier or just want a treat, or have a social event etc. If you set your minimum at the 1,700 and your maximum at 2,300 - you will still be set to lose between 2 and 3lb a week assuming the estimated TDEE and exercise calories are reasonably correct.

    2-3 pounds WITH 500 calories burned, right? Or 1,800 maximum if I don't work out. Am I getting this right?

    I always just thought you pick a calorie number like a number on a dart board and just go to town. I didn't realize how messy this way. I am utterly confused. I suppose as long as I'm losing, it doesn't matter to most people. But to me, I like to achieve my goals in a given time frame. I'd like to know what to expect. If working out gives me a higher TDEE, naturally it gives me a larger deficit. However, If I'm eating 1,700 and burning 500, that is technically 1,200 a day. Which is why I must eat those calories back, right? That's way too little for an obese person. If that's the case, and I eat back my calories, doesn't my TDEE still stay the same?

    You have the math a little off. However, I just want to clarify - the TDEE that you gave - the 2,700, is that assuming no exercise?

    You might want to drop the "time frame" and work on the process to be honest because weight loss isn't linear and you may well have weeks when you lose nothing even when doing everything right

    BMR (the amount of calories your body consumes just existing eg in a coma) + your daily activity (eg just pottering, walking, cleaning etc) - this = NEAT ( the number MFP gives you)

    Add in purposeful exercise and that's your TDEE

    I don't use the TDEE, I just use MFP's setup. So whatever calories it gives me, I eat that, then I eat back 50% of my exercise calories.

    TDEE and MFP are different approaches to determining calorie deficit.

    With TDEE, you're choosing a standard deficit to eat daily under the assumption that you are exercising x amount per week.

    With MFP, you go by the number determined by your current weight and desired deficit. You can eat back up to half of your exercise calories.

    Honestly I think the MFP method is a better approach because you won't miss losing weight if you don't consistantly exercise as much as you plan to; you just won't get to eat quite as much on those days.
