to eat or not to eat....

Should you eat the exercise calories or not? This has been always the question for me. I generally dont eat all of them, but should I?

    You can try...you will get a better idea of how accurate they are when you log for a while and track how much weight you lose.

    It's how MFP is designed and it makes it easier to meet your nutritional goals and still enjoy a wider variety of foods while still being in a deficit. Why wouldn't you?

    Thanks both for your reply. I will try to eat all of them for a bit thanks for the great tip.
    I just generally dont feel hungry to eat all of it so what gives... I guess I should be happy.
    Also I only notice it after dinner and then it is too late to eat 500 calories lol

    Do you use a scale to log your food?

    Assuming that 500 calories is an accurate estimate of how many calories you're burning through exercise, you can always roll them over into the next day. You don't have to cram them into the end of your day, your body doesn't do a hard reset at midnight.

    As others have said, MFP is designed for you to eat back a reasonable estimate of exercise calories. Be sure to set you MFP activity level (in your profile) based on non-exercise activity (like home chores, job, non-exercise hobbies, etc.).

    The real test is actual weight loss rate after 4-6 weeks (comparing same relative point in at least 2 different monthly cycles for premenopausal women). Losing weight too fast creates health risks (don't want that!), but you do of course want a sensible, steady loss rate. Eating back exercise calories is just part of finding that balance.

    Someone who sets an ultra slow loss goal (like 0.5lb/week, even when they have many pounds left to lose), and who does small/irregular amounts of exercise, is probably fine just letting exercise calories increase their calorie deficit, because in total they won't lose too fast. But someone who sets up their profile for 2 pounds a week loss, then does hundreds of calories of exercise most days on top of that . . . well, that can be a path toward unsustainability (such as binges), weakness, fatigue, or worse health complications. For sure a problem? No. But for sure higher risk.

    Best wishes for success!

    Yes I weigh all my food religiously with my kitchen scales. I've been tracking for two weeks and lost 2kg so far so it is working.

    Congratulations on your weight loss!

    Maybe start with eating back half your exercise calories. Many exercise calorie estimates are rather off. If you find you lose too fast (and lose too much muscles) then eat back more.

    Thanks everyone this has been really insightful read and has made me appreciate the calories I have left more. I have always thought that as long as I don't feel hungry I should be ok, but on some days I have quite a few calories left and then end up munching chocolate in front of TV because I can (Which then throws my macros out of the window!! :D )

    If you are trying to maintain your weight and not lose than sure you can eat them back . But if your goal is to lose weight I don’t see why you would want to eat back your hard work. Don’t forget , your calorie deficit should be made with food not exercise

    Try out different methods, see what works for your goals... I did this and got to know more about how my body reacts to certain situations. One week you eat the 'burned calories' as well, one week you don't and then you can see what works for your goals.
    I don't eat them back on now, trying to cut some weight.. But this would not necessarily work for others.. As long you feel the fun of it you should try whatever works within your comfort. No right or wrong, as long you don't OVEReat you daily macros

    One week you eat the 'burned calories' as well, one week you don't and then you can see what works for your goals.
    I fully agree with notion of experimenting but I'm skeptical that one week can tell you much. Three months should yield fairly definite results. But I would suggest letting at least a month to go by before drawing any conclusions.

    I would also like to add I sit on my bum most days because of work but always go for walks to get at least 10k steps each day as well as do some weight training with my dumbbells

    This conversation has been really useful for me. I am on 1200 cals a day so in other words if I do 500 cals worth of exercise it takes it down to 700? - which is way too little.

    1200 calories is the bare minimum for women.

    How tall are you?
    How much are you wanting to lose?
    How fast are you trying to lose it?

    I am looking to lose 10 kg (which I think is about 25 pounds or so) and I am 5.5...Not really in a rush but I am struggling to meet my calorie goals even if I am not dieting on most days. And then there are days I eat super unhealthy (well was still 2 weeks ago).

    What do you have your rate of loss set at?

    I agree with @AnnPT77 's point. You can't really micro-engineer the project at the beginning, though people do try. There's a certain amount, a lot actually, of necessary "see how things go" and fine tuning. There's broad agreement that you need 6 weeks of data to draw any conclusions. That is, 6 weeks of getting on the scale, counting your calories, and getting a feel for things.

    In the meantime, eating back half your exercise is a good idea. After 6 weeks you'll be able to see whether that resulted in the correct amount of weight loss. Calorie estimates for exercise are all over the place and often way too high, and all you can do is put a temporary stake in the ground as far as what % to eat back, and see how it goes for six-ish weeks, and then fine tune.

    The main thing to fully grok is that MFP's NEAT-based system is going to give you less calories than a TDEE-based calorie tool IF you work out regularly, waaaay less, because it expects you to add your exercise cals to your food intake.. Translated into English:

    A tool like TDEEcalculator.net says, based on your gender, age, any workouts you do, etc., "Your break-even calorie level is 2200", and you on your own decide you want to lose a pound a week, which requires a 500 calorie deficit, so you eat 1700.

    MFP doesn't work like that. It assumes the 500 cals of cardio you're doing will be counted separately and eaten back, and therefore tells you to eat 1200, meaning "1200 PLUS your 500 exercise calories".

    Either way, if your break even is 2200, you have to have 1700 net calories per day (food minus exercise) to lose a pound a week.

    In this little example, if you use MFP's system and don't eat back the cardio, you will end up eating 1200, which is way too little food for a 1 lb/week goal. So that's why you eat the exercise cals back when using MFP. It's the same amount of food in the end, 1700 calories, it's just added up differently. The mathematics don't really matter and a lot of people use TDEE not MFP's system. But the point is, if you got a calorie target from MFP, it assumes you will eat back your exercise calories, and if you don't, you could easily fall into an unsafely huge calorie deficit. Try to avoid that; it isn't sustainable and isn't good for you.

    Just for clarification on this...

    If the calorie goal is set to 1800 calories per day, and one exercises and burns 750 calories, lets say you aren't entering exercise calories into MFP...then one would actually only be eating only 1,050 calories, even if they ate their calculated 1800 calorie daily limit? And this is because you still have the calorie deficit that MFP calculated which is why you should eat your exercise calories?

    If the BMR is 1500 calories and the TDEE is 2300 calories, the daily calorie limit is 1900, and one does't add in the 750 exercise calories into MFP, then this person is only eating 1,150 calories?

    Huh...maybe I should be eating my exercise calories because I'm losing inches and not scale weight and its been 5 weeks and I'm getting bummed.

    What about intermittent fasting in conjunction?

    See I'm not losing weight at 1800-2000 calories a day and I don't eat my exercise calories back. I'm losing inches but I sit all day for work, then I exercise 30-120 minutes 6 days a week in the form or resistance training, walking, hiking, running, spinning, or body weight exercises. In 5 weeks, I've lost two pounds and about 6 inches off my body overall. I'm wondering if I should be eating those exercise calories back based on what my fitbit says I burned. I thought I have been overeating this whole time.

    Don't worry about BMR. It's a hypothetical number of how many calories you'd burn if you were in a coma. Since you're not in a coma, it's meaningless and shouldn't play any role in deciding how much to eat.

    Yes, if you eat 1800 calories and do 750 worth of exercise, you are getting an effective 1050 calorie intake, which is too low. No question. Now, that 750 worth of exercise might actually be more like 400 since calorie estimates for exercise are often very high. So it may well be that your net calories, i.e. food minus exercise, is really round 1400 in this case. The problem being that it's supposed to be 1800. So that is why you eat some of the exercise calories back.

    Intermittent fasting will not impact this.

    Thanks for the response. I did make an edit to my post with additional information if that may help. I use a fitbit to estimate my calorie burn, which in all cases is a smaller number than what MFP gives for the same exercise. I officially have no idea how much I'm supposed to be eating now. On average, based on my fitbit, I burn 2500-2600 calories per day with exercise. I'm guessing I should be eating about 2000-2100 calories per day if I were to set my own goal number and not add in exercise calories. Would that potentially work?

    Um, you're not losing weight but you're losing inches and you lost two pounds and 6 inches? That didn't make sense. :) Nothing's wrong here other than you should eat some of those exercise calories back.

    Yes. That is the TDEE method, versus the MFP NEAT method, and either is fine. You are saying that your all-inclusive break-even is 2500-2600, including any exercise you're doing, and if that is true, then eating 2000-2100 should give you a pound a week of weight loss. So everything is solid with that plan, except that you may find the 2500-2600 isn't quite accurate. After 5-6 weeks, if your weight loss isn't 1 lb a week, you can (and should) adjust your caloric intake up or down as needed.

    Depending on your age/sex/weight/height/blahblah, the 2500 may well be pretty close, though perhaps a bit high. As a 247 lb 5'10.5" male, my NEAT is 2350 and with exercise my TDEE for the day is usually 2750-2800. So I don't find a 2500 TDEE to be something that's wildly out there, and in 5-6 weeks you'd know for sure whether that was the right number. Just be sure to count calories accurately and diligently during those 5-6 weeks and not take cheat meals, so that you can get an accurate picture of things.
