Eating Back Your Exercise Calories

Options
I'd like to get some opinions on eating back your exercise calories. This is something I typically try to avoid but I do it from time to time, like tonight, and then I feel guilty about it. It should be fine for me to eat them back right? Especially if I don't do it all the time?

    I think everyone is different but I eat all of my exercise calories back if wearing a HRM and I reduce MFP estimates by 30% if I am not wearing it and eat that amount back

    This is a pretty big debate that pops up continually on the main forums.

    Should you, or should you not, eat back your exercise calories? The answer is: It depends.

    Here are some background definitions before going into this:

    BMR (Basal Metabolic Rate): The number of calories you burn at complete rest.
    EAT (Exercise Associated Thermogenesis): Caloric requirements of training, or training expenditure.
    NEAT (Non Exercise Activity Thermogenesis): Caloric requirements of activity that is not planned exercise. Vacuuming, driving, brushing your teeth, for example.
    TEF/DIT (Thermic Effect of Feeding or Diet Induced Thermogenesis): Caloric expense of eating/digestion.
    TDEE: (Total Daily Energy Expenditure) = Sum of the above. BMR+EAT+NEAT+TEF


    Exercise calories, as they are typically used in MFP specifically, is represented by EAT in the above definition. Whether or not you should eat your EAT (giggity) depends on what system or method you are using to calculate your intake needs.

    If you are using most other online calculation tools to determine an intake estimate, that estimate is going to already include EAT as part of the suggested intake. For example, it will ask you an activity factor that includes an average of your exercise, and with this it increases your TDEE to account for the fact that you are exercising.

    If you are using MFP to tell you how much to eat, that estimate is NOT going to include EAT as part of the intake estimate.

    Myfitnesspal uses a caloric estimation tool that expects you to eat back calories burned during exercise.

    Consequently, MFP will essentially give you a LOWER intake estimate than an external TDEE calculator would give you.


    In other words:

    You tell MFP: I'd like to lose 1lb/week.

    MFP says: Hey, you should eat X calories every day to lose 1lb/week.

    You then decide to exercise and you burn 400 calories.

    MFP says: Hey you pecker, you said you wanted to lose 1lb/week. Now you need to eat X+400 because you told me you wanted to lose 1lb/week.


    So based on this:

    If you are using MFP to tell you how many calories to eat, you should probably be eating back some portion of your exercise calories.

    If you are using an external calculator and then customizing your intake to match that, you should not be eating back your exercise calories.

    Lastly: Exercise expenditure is often over-stated.

    My general opinion is that it's much simpler and uses less guess-work to use a custom intake and just forget about the exercise calorie model entirely, but that's a different topic of sorts, more discussion of which can be found here: http://www.myfitnesspal.com/topics/show/819055-setting-your-calorie-and-macro-targets

    Eating only 1200 calories a day is usually hard for me (and then it yells at me if I don't eat at least 1200..can't win..) So I naturally eat back SOME of the calories, because I wouldn't be able to continue on this path if it meant always feeling deprived. I often negotiate with myself. Craving froyo? Make sure I run to 'afford' it.

    Generally I try not to go toward sweets (addictive) but splurging once in a while is fine and makes me able to stay with it for the long haul. I just try to keep my overall calories at a deficit.

    Depends. If you are already on a deficit and exercise for the health benefits, do eat them back if it would put you into a too big deficit. However, if you exercise to create a deficit, then eating the calories back isn't the most logical option.

    I wear a BodyBugg to help me manage my true calorie expenditure. I have to be honest, either it is not as accurate as it claims or you just don't burn as many calories as you think you might...My BMR is around 1750. I rarely sit down during the day (busy mom of 4, ages 19m-10y, own a soap making business filling orders and making stuff all day, etc)...if I don't do any exercise on purpose that day, I still only burn about 2100 calories that day according to my Bugg.

    I do not eat my calories back unless I want to...if I am struggling that day with my food choices, I will eat the sushi. Because eating 1500-2100 calories one day is better than giving up completely. Some days I am motivated to lose all of this weight in 3 months and other times (like when on my period...it is near impossible to be motivated or stay at 1200 cal for those few days), I am fine with being the tortoise...low and slow is better than not at all.

    I'm glad to see a number of people saying the eat them back, makes me feel better :-)

    I wear a fitbit flex all day and a HRM when I work out to help with calories, I assume what they tell me I'm burning is overstated. I usually just eat back calories if I'm having a really hungry day and then I never eat them all back, just a portion of them. I've had a really hungry week this week, seems like I'm struggling, sigh.

    I wear a Fitbit and I think it actually understates how many calories I've burned. When i do strength training and lifting it doesn't count that ... Just steps. When i work on training for my 5K then I am good.

    I think if you are hungry then eat them back. If you start to see that you are not losing weight then you mifght want to change something.

    I wear a HRM, so I usually try to get back at least half (or sometimes more) of my exercise calories. In the end, you do what works for you :-)

    I have a Bodymedia Fit and yes, I absolutely eat my calories back! Some days less, some days more, but it averages out over the course of a week. It's been working, I've lost 122lbs in 15 months. What good would it do me to have a bigger deficit if I feel deprived and fall off the wagon? I would rather lose at the rate I told MFP I want to lose it at, exercise, eat ice cream everyday, and stay on the wagon. :drinker: Plus, I am getting closer to goal and it will be an easier transition into maintenance, if I am already eating more.

    If you're going to eat them back, make sure you're estimating them properly. Most people are vastly over-estimating what they burn, and as a consequence, eat right into their planned deficits.

    If you are using a FitBit or BodyBug or HRM to get your calorie burn, you are most likely over-estimating. If you are using MFP for anything like HIIT/intervals/circuit, you are most likely over-estimating.

    Absolutely. I remember back when I started, MFP had me burning 1200 calories per hour exercising moderately on a recumbent bike. :noway: In fact, it would still give me 700, while my Bodymedia gives me 300 for the same activity. Because I lose weight fairly steadily and am in line with my goals, I know that for me, my Bodymedia does not overestimate by very much.

    MFP is designed so you eat your exercise calories back ALL the time and I do eat mine back everytime. The problem is that calorie burns given here are "generous" ....so eating a percent back is prudent.

    If you have a goal of reducing your body fat percent.....then you will want to eat back some calories. Eating too little (big deficit) ....results in fat+muscle loss.

    How does using a tool as designed make a mockery of anything? That's like saying driving nails with a hammer makes a mockery of driving nails...makes zero sense. I think it's funny how all of you use this tool yet you think it's trying to sabotage you or something when it comes to exercise calories...srsly...this tool is really friggin' easy to understand and use properly and in my experience, using a tool as designed ultimately yields the best results. I mean...you could drive a screw with a hammer but a screw driver would ultimately yield better results....

    Do not feel guilty about that. It is the best thing to do. If you are already eating at a deficite and THEN add on some exercise you are going to stress your body out. You will gain back the weight or stall the loss all together by eating too low. Do not start your body. Feed your body good choices of nutrients and fuel that activity to grow muscle. Seriously. Have you been starving yourself intermittently on "diets" your whole life and keep winding up right back here with weight to lose again? I'm going to guess yes. Well it didn't work did it? So why keep trying it like it was your fault it didn't work. Eat like an athlete and fuel your active body. Make clean unprocessed choices for balanced foods. You will be so happy. Love your food and never feel guilty about feeding your body.

    Yes eat them back, MFP gives you a calories goal with a deficit in it already before you exercise. Exercising will make your deficit even bigger which is why MFP gives you calories back to eat so that you can stay within a healthy deficit.

    This is very succinct...thank you

    I dont know how to bold so here goes...........HEALTHY DEFICIT!

    I don't eat all mine back. For me, it's near impossible. I'm supposed to eat 1200 calories. I've already eaten 350 for bfast and lunch. With my exercise points of 432, It gives me 1282 more calories to eat! There's no way I can eat that much. But it does help when I want a second glass of wine with dinner or a real cookie that's not low fat.
