I am starting to get confused about this one.

Do I need to eat them back or not?

    Did you use mfp to calculate your calorie goal?
    If so, yes, you should eat more on days when you exercise.

    If you used another system to calculate your calories, then probably not.

    Some days I do, some days I don't. It seems I lose more when I don't.

    Yes, you should eat at least 50% of them.

    Yeah I only use MFP to calculate.

    But if I am eating back what I burn how do I lose weight?

    The deficit is already built in unless you set the account to maintain.

    Diet is weight loss... exercise is fitness.

    I've been on MFP for a couple of weeks now and have never eaten them back. Must admit, though, I am a bit worried about it. I am losing just under 2 lbs a week. Is there anyone else who has never - or seldom - eaten them back? Are you still alive? :smile:

    plenty of people dont but you will increase muscle loss doing it this way and slow down your metabolism as your body will catabolize your lbm.

    I eat up the deficit calories. . .
    Rather I exercise when I eat more than my calorie limit to make up . . .
    But right now Im doin just light aerobics . . . and burn about 200 calories a day

    Thanks psulemon. I have been exercising in an attempt to save muscles. Oh, well, I see that perhaps I should at least eat some of them back. I am just impatient to lose weight and feel that if I eat them back, losing will take longer.

    Still a bit confused.

    So does that mean I don't have to make up my net goal?

    I would say yes but mfp can over estimate the exercise calories. This is why i suggest eating 50% of them. If you get a hrm, then eat at least 80% of them.

    Losing will take as long as MFP tells you. If you set your goals to 2 lbs / week and MFP tells you to eat 1200 calories per day, you eat them.

    If you exercised and lost 500 calories you eat 1700 calories. You will still lose 2 lbs per week. If you don't eat them back you risk losing too much weight too fast. Your body will adjust, slow down your metabolism and then you're at risk at gaining instead of losing. Its not the same for everyone, but its the norm.

    Don't eat if your body tells you to eat. If you were a gluttonous hog for 10 years, your body will never tell you to stop eating and some people eat themselves to death this way.

    I always eat my calories from Exercise back. I hear that if you don't then your body goes into starvation mode and stores fat. I have been losing about a pound a week eating my exercise calories back. If I want to cheat on food, I exercise to make up the calories. It works for me.

    I eat them back when I'm hungry but don't bother if I'm not. I usually lose more on the weeks that I dont eat them back but saying that I do lose every week albeit only half a pound some weeks.

    The fat loss comes from a calorie deficit.

    So you, in the course of the day, use say 2000 calories. If you then eat 1500 per day you will be under by 500 cals per day.

    So then if you work out you might use 3000 cals that day. You would then be 1500 cals under.

    That is just the same as if, on a 2000 cal day, you ate 500 cals.

    There is a reason why you can't just stop eating and lose weight, there's a whole body mechanics that would mess up so basically, exercise doesn't speed up your weight loss, it just keeps you healthy while you do it and, if you are lifting weights, will help preserve your lean body mass, because you are aiming for fat loss, not weight loss after all. Weight loss is indiscriminate. Fat is specifically what you are aiming to lose. Exercise can also be used as a tool for those who struggle to only eat their calorie goal and want to eat more. Do some exercise and you can eat some more.

    To repeat though, it is not a tool to lose weight faster in most circumstances.

    Wow, perfect answer by Chris. If you're still confused after that than nobody can help you.

    I wouldn't. You'll lose weight faster if you don't. In my opinion, it's like rewarding exercise with more food.

    I've been eating some of the calories I've gained from exercise but then I also try to think of it as a weekly total rather than a daily total. If I've gone over on Monday say, I'll exercise and "save" the calories to make up for it. In the beginning I was losing 2.5 lb a week which is a bit too much but its leveled out now I'm eating a bit more and exercising a bit less!

    As long as you are eating 1200 calories approximately you should be fine as this is about the level of nutrition you need to keep functioning - but make sure you are eating a varied diet to make sure you get all the nutrients your body needs xxx

    I dont think this is necessarily true. If you incorporate some resistance training into your fitness routine your muscles wont just poof dissapear or start to shrink. Just look at all the different type of intermittent fasters out there who routinely eat below their maintenance levels and still have great success.

    If you want to save muscle incorporate resistance training...either with weights or some sort of body weight exercise. Start out slow and shoot for more weight, reps, or whatever each week.

    If you're goal is to eat 1500 calories a day out of 2000 you have a 500 calories deficit. If you exercise and burn 1000 calories and eat them back, you have a 500 calorie deficit. Nothing has changed. You're still rewarded with weight loss and none of the risks associated with it.

    Hey hun,

    Ok lets try this,

    Your body needs around 2000 cal to function every day or maintain weight.

    MFP has set my cal intake to 1500 which is 500 deficit ( to loose weight)

    If I gym and burn 600 calories, I am allowed to eat back at 600 , (they cancel eachother out) and my 1500 then I am still at a 500 deficit,
    So what I do is I eat most of those calories back if I only eat back 400 I run at a 700 deficit (500 + 200)


    I just re read this, I hope it makes sense to you:laugh:

    My sugegstion is eat back half of what you burn, to make sure you fuel your body for your next workout. if you are still hungry then eat more
    When you do extra things like gym etc its not calculated into your 1500 that MFP suggests a day

    I dont as I struggle to eat my calorie allowance anyway .. but I have to say after a week or so my loss slows down .. it discourages me .. I go off the diet , .. then I restart at a later date and start the process again
    from this and the above replies I would say that we should eat at least half of our excercise calories . Not sure how I am going to do that personally

    Thats because of normal weight fluctuations. Be it that you took a good dump this morning or didn't drink fluids yet... But no normal person will lose that much in a day unless they are very very sick.

    MFP has already created the deficit for you so earning calories by exercising can be eaten back but I wouldn't advise eating them if you're not hungry or at least peckish - what would be the point as you'd be eating for the sake of it. On the days I exercise I usually have something a little more calorific than normal or maybe have a cheese sandwich instead of wafter then ham! LOL

    Okay I get it now XD

    But then after I "Earn" these new calories MFP tells me that I haven't consumed enough if I don't eat them back.
