Am I supposed to eat my exercise calories??

I've heard yes, I should eat the calories I burn, and no, I shouldn't. The 2nd argument makes a bit more sense to me since less calories = pounds lost.
So should I or shouldn't I, and why?? Confused...

    Is your caloric intake suggest by MFP already set to lose weight each week? If the answer is yes, then you have to eat those calories or the deficit is going to be much larger than it needs to be.

    You should depending on how much you burn and what your net calories are. If after you workout, your net is less than say 1200 or 1250- by all means eat some of those calories back. If you net around 1300 or more, it's a personal choice to eat the calories back or not. Just don't dip too low.

    It depends on the person. For me, no. I do not. When I do eat my calories from exercise, I don't lose weight. In fact I have gained weight. And no it's not muscle, I do measurements.

    The only way for me to lose weight is to stick at 1750 calories despite how much I exercise. It's difficult to do because I get so very hungry but it's the only thing that works for me.

    Yes - eat them back (at least some of them ... anyway)

    It does seem like you would lose weight faster by reducing your calorie deficit even further ..... this is not true. Your body needs those 1200 NET calories for general everyday bodily functions - breathing, heart pumping, etc.

    You want to lose fat (just fat) and keep your existing muscle or build even more muscle. Starving your body will not help you keep lean muscle.

    Yes you should as your activity level, recommended caloric intake, assumes you will do no exercise, once you exercise your body requires more fuel.

    Not eating them in only a good idea if you set your activity level to active or higher to account for exercise. Changing your activity level will give you more calories so you will be eating enough, without the thought of "eating your exercise calories".

    Essentially you are setting your TDEE (total daily energy expenditure) then creating a deficit from that to lose weight. This is what most trainer/doctors/nutritionists do. Most professionals will tell you not to eat you exercise calories back because they added it into your TDEE, whereas MFP ignores exercise and only accounts for it when you perform it. Either way should get you to the same place.

    As an example say MFP gives you 1450 calories to lose 1 lb/week, and you plan on exercising 5x/week for an average of 400 cals per workout. well MFP will tell you to eat 1450 on the days you don't workout and 1850 on the days you do whereas a "professional" may tell you to eat 1750 everyday regardless if you workout.

    So for the week MFP will have you eat 12,150 (1450*2+1850*5) whereas doing it the other way will have you eat 12,250 (1750*7) almost the same number of cals for the week. The issue in not following MFP is if you don't workout the full 5 days or burn more or less than planned. If that is the case you may lose more or less than your goal, whereas MFP will have you lose your goal amount regardless how much you actually workout.

    What many MFP do is take the low 1450 and not eat back exercise calories which is wrong, if you are not eating them back then your daily activity level should reflect the higher burn with would be covered in the 1750/day above.

    If you don't, you have to be REALLY careful not to exercise yourself into "starvation mode". The numbers are a plus or minus thing, but for the most part they indicate a deficit already, so be careful not to end up with way more deficit than is healthy. I generally come close to eating mine back, but I don't worry about the occasional day that is up or down from the graph, even by quite a sometimes.

    Prepare for a whole myriad of answers!

    There is no set rule to this.

    Some eat them all back, and lose weight.

    Some eat a portion of them back, and lose weight.

    Some eat none of them back, and lose weight.


    If you find you have enough energy without eating them back, go nuts!

    If you find you are tired and weak without eating them back, start eating!

    Bear in mind that if your calorie deficit is too great, then your body is going to kick into conservation mode, which means you'll slow down your metabolism and lose energy while storing more fat.

    The formula isn't quite as simple as fewer calories = pounds lost. Too few is bad, too.

    I eat what my body tells me it needs to fuel itself/recover etc.
    So some days I do, some days I do not.

    I eat my exercise calories back when I want to...and I usually do. At the very least I make sure I eat some of them back.

    I think it depends on the person. I never eat back my calories and I seem to be losing weight. Also, I never dip below 1200 calories either. I guess as long as you don't dip too low, which I think is below 1200-1300 per day you're good.

    Why would you want to lose faster than your goal, your goal should be a goal for a reason. remember a safe deficit to lose weight is 250-1000 cals/day, if you are set up for a 2 lb weight loss your deficit is already 1000 cals so if you burn more your deficit grows and may not be healthy for you stats. Having too large of a deficit will cause your body to burn muscle, not just fat, to use as fuel as your body can not break down fat fast enough.

    YES, and no, depends how you set up your goal:

    1. MFP way - yes, eat your calories back, it already have build in deficit for you
    2. have a fixed daily maintenance calories - no, use your exercises burn calories to create the lose weight deficit

    Really. You can trust Mike and the MFP site that they know what they are talking about.

    you can use search

    Or you don't have to eat them back and just do whatever.

    I pretty much apply the same rules to my dieting as I do driving. I roll though the stop signs and I turn right on read. I mean if no one is watching its all good.

    Just remember that like any machine, your body must be fueled in order to run properly. If your caloric input leads you to fatigue,
    then adjust your intake. No steadfast rule on using or not, those calories depleted by exercise..

    When I eat closest to 1200 net I hardly lose, when I net closer to 1400 net I lose more. If you are set to achieve a 2# weight loss weekly your calorie intake is already lower so you definitely should eat back the exercise calorie. Try one month at different net levels and listen to your body.

    I wait for the answer slam before posting this. I tried to break down the math for you to make it understandable. I hope :(

    Example:

    Let's say 2000 calories is what your body needs to maintain current weight.

    To lose a pound per week, your weekly caloric expenditure needs to have a negative balance of 3500 calories per week, which is 500 per day. Basically, you need to end the day at 1500.

    You can achieve this by either diet or exercise or a mix of both. The best benefits come from mixing diet and exercise.

    So let's say you move your caloric intake to 1750 and decide to burn 250 calories from exercise each day of the week. That will put you at 1500. 250 calories less from diet + 250 calories burn from exercise = 500 calorie negative balance.

    Now assuming this, if you exercise more than you allotted (lets say you ran further), your negative balance is going to be affected. Let's say you instead burned 500 calories from running 5 miles. 250 calories less from diet + 500 calories = 750 negative calorie balance. Thats way more than you need to achieve 1 pound of weight loss each week.

    With a 750 negative calorie balance, you'll have to eat back those extra (and i emphasize extra) 250 exercise calories as they were not included in the original goal.

    Does this make sense?

    Edit: I should also reiterate what others have said already. MFP allows for you to have the deficit built into the suggested caloric intake based on your weight loss goal. If you have your caloric intake already preset to lose the weight through diet alone, those exercise calories are extra calories that need to go back into your body.

    I feel more sluggish when I eat back net calories. I try to stay at 1500 cals regardless of my workouts. If I burn 3500 cals in a day I tend to eat more. It's at your discretion. Remember the less you eat the more you lose. If you watch the Biggest Loser you see them losing a lot of weight working out a lot while maintaining a 2,000 cal diet.

    I don't but have increased my daily intake beyond what was recommended by MFP to 1550 calories per day on average vs the 1200. this works for me. I have had my metabolism tested and it's high so was told to eat about 1400-1700 to lose weight! Most of my friends that are on MFP are trying to eat around 1400 without deducting for exercise. So guess it's up to you. People just burn calories so differently, I figure its easier and more accurate to track what I put in, then what I may be burning through activity.

    What they do on BL is not healthy, and they are being monitored constantly by doctors. If your deficit is too large and you don't have a lot to lose you will lose a large % of lean muscle, so ask yourself, do you want to lose fat, or weight, if the answer is fat, then make sure your deficit is not too large and eat back the exercise calories, as MFP intended.

    If you don't eat your exercise cals back please change your activity level to active or very active and eat all of those cals instead.

    Eat some. i lose a steady 3-4 lb a week, eating my food calories and a couple of hundred into my exercise calories. I've lost a loyal of weight. The only time I've ever stalled was when i let my net drop too low by not eating anything back.rop too low

    Yes, you make sense.

    But your edit is what I want to highlight. I think this is where the discussion about eating back calories often goes off the rails.

    It drives me crazy to see the question of eating exercise calories come up so often and it get so quickly answered without considering context or other important information.

    It's like somebody posting a topic with the question: Should I wear a jacket?

    How do you answer that? Well, are you cold? What else are you wearing? What is the temperature where you are? Will the temp fluxuate much where you are? It's just not a simple yes or no question or answer. And because many dieticians, trainings and doctors are used to setting calories with the activity levels *already included* - you end up with people on MFP saying "but my doctor/trainer/best friend said..." And it goes even farther than that, because even within MFP, there are details to consider. How you set up your account matter.

    Got it? OK. Stop answering Yes or No to the eating exercise calories question. It's not that simple, even though *generally* on MFP (because of how the site is designed), the answer will *usually* be yes.

    But deathstarclock said it better and more succinctly that I could.

    So, even though I quoted you above, I am going to type your words again. Read these words:

    If you have your caloric intake already preset to lose the weight through diet alone, those exercise calories are extra calories that need to go back into your body.

    Now, everyone read these words again. This time, without your mouth moving:

    If you have your caloric intake already preset to lose the weight through diet alone, those exercise calories are extra calories that need to go back into your body.

    You have to remember though that Biggest Loser was a T.V. fantasy camp, engineered to appeal to it's audience, not to what's healthy or what will work in the long run. I wouldn't advise taking it as gospel on what's good for you.

    If you read the blogs of the contestants after the show ended, you find out that that the t.v. show demanded they exercise against doctors orders with pulled muscles and worse; dehydrated themselves severely before the measure by working out in layers of clothing and not allowing hydration in a hot yoga room; that a "week" of exercise was anywhere from ten to fourteen days in real time, and most to all of the chosen diet/exercise combo's were directly against the doctor-on-the-show's orders. Check it out; here's one who speaks out.
