I have noticed this before and now as I get back to working out after a 6week break - I really notice it again. As I'm working out more my appetite has decreased. I leave about 200c not eaten - and that's in addition to the 250c deficit that MFP creates for me. ??? I know too - that in a few days that will change and I'll eat all of my calories (at least that's the pattern in the past). But it makes me wonder about changed in brain chemistry or body chemistry that result in this (I'm a bit of a nerd).

Anyone else experience this?

Or know anymore about the reason behind this?

    I've found the same thing. I asume it's hormonal but don't know.

    As you are working out more, you are getting into more shape that your body doesn't utilize as much energy; thus, requiring less consumption of food for energy. :-) It's normal and it happened to me when I first started out. I was undereating.

    Exercise is an appetite suppressant for me too. It just is that way for some people. But it usually only lasts a few hours at most - and if I don't eat enough that day, i'll wake up RAVENOUS and STARVING the next day.

    depends on the workout .. HIIT style workouts and weight lifting with medium-heavy weights higher reps take away my hunger.
    steadier cardio and heavy lifting make me into a bottomless pit.

    i try to do a mix of the two

    Opposite problem-- the more I workout the hungrier I get.... wish I had your problem.

    Ditto. I'm ravenous after a workout.

    A long run completely kills my appetite. Lifting turns me into a Dyson. That's the main reason I switched to eating the same amount every day with a weekly average for exercise mixed in, instead of adding exercise calories each day.

    Sometimes when I am hungry and go to workout, I am not hungry anymore, but it only lasts for a few hours and then I feel totally "starving"

    I feel that way too, and I wondered if it was my body finally pushing through and speaking louder than my emotional hungers.

    I forget the resson, but yes it's true and an added bonus to working out! The only exercise I know of that INCREASES appetite is swimming in cold water.

    I am having this same issue today. I worked out hard with running and strength training, and I have not been hungry since then. I don't want to stuff myself with food because then I'll feel bloated. I was thinking maybe it was all the ab work I did today.

    Thanks for this post.
