What happens if you eat exercise calories back?

Hey guys.

How is everyone doing?

A few months ago I bought a BodyMedia Fit armband so it pretty much tells me how many calories my body burns everyday. On workout days I'm burning about 2600-2700 calories a day. Rest days are about 2200-2400. I know that to lose weight I have to have caloric deficit and to build muscle I have to eat at a surplus. But what happens if I just eat what I burn everyday? Am I going to neither lose fat nor build muscle? I'm working with stronglifts 5x5 now.

Thank you for your input. I just can't figure it out lol

    If you eat above TDEE you'll gain.
    If you eat below, you'll lose
    If you eat at TDEE, you'll maintain.

    You might look at a TDEE calculator just to double check what those numbers say.
    I know they're not 100% perfect, but... neither are fitbits, HRMs or any of those products.

    Thanks for the input.

    So if I eat at TDEE there is no difference whether or not I work out? In both cases I'm just going to maintain? I figure those two cases can't be the same can they?

    Thanks

    If you do not eat back the calories from working out you will lose weight. You can still gain muscle doing this, as long as you are doing the strength training correctly.

    This podcast gives a wonderful explanation as to why we "should not" eat our exercise calories back.

    The discussion starts at minute 10:20 if you want to skip the first part. Give it a listen, certainly helped me to understand why I won't be eating my exercise calories back any longer.

    This is only the case if you are severely over weight. You CAN tone your muscle, and make it appear bigger by giving it definition. But, you cannot BUILD muscle and gain eating at a deficit.

    The TDEE calculation takes in to consideration your fitness activitiy, in the caluation itself. So, it would be two totally different numbers if you workout, versus not working out. Does that make sense?

    So if you calculate it with your workouts, and eat at that TDEE calcuation, you'll maintain. If you calculate without workouts and eat at that TDEE, you'll maintain.

    I'm so confused. I calculate my exercise calories into MFP. Even if I eat my exercise calories it still says in 5 weeks I'll lose weight. Not maintain. Lose.

    That's because MFP has already built in a deficit.

    Despite the title, it sounds like the OP is talking about eating the total number of calories he burns in a day as reported by his BodyMedia Fit, whether from exercise or just living his life. In other words, his TDEE or maintenance level (correct me if I'm wrong, OP). That's completely different from what you're dong with MFP.

    So does that mean I'm good? And not screwing the math up to lose weight? My problem in the battle over weight is not working out. I love doing that. It's balancing the food portion that messes me up.
