Share Will Exercising and Endless Days at The Gym Help Me Lose Weight? | Surprise! By Mark B. / June 21, 2018 Recently I read this question on a Forum, “This may sound weird, but I lose zero weight when I exercise, but I can lose almost a pound a day when I don’t. I used my elliptical for half an hour and ate my usual 1,250 calories. The scale didn’t budge. I tried adjusting my calories and watching my sodium, with no luck. I stopped exercising and just watched what I ate. When I do that, I lose a lot of weight.” Why is this?
