Oh, definitely. I've lost upwards of 30 pounds over the past year and a half. Much of it is related to changes in my diet, but exercising regularly has definitely helped my diet. Personally, I'm much less likely to eat in excess after exercising because I don't want to "waste" my efforts.

I felt this way too, but often I ended up eating bad food because after a while I didn't value exercises as much (went back into a OK zone).

Also, told this already, massive health failure forced me out of sugar coated, processed food and beverage. Our life styles is way too easy onto eating to satisfy our tongues and not our body. When stuck in this corner, eating raw veggies, you'll start to notice a lot of enjoyable tastes, and drop in fat aftertaste and overall a realization that how much sugar 'drugs' your brain. It's very hard to not want to take a big bite of cake or chocolate, hamburger etc etc, and inside the comfy zone of our culture, if your health allows it, you'll never have a way to sense that.

It helps you keep your choices in perspective for sure. Also, for me, if I'm getting a lot of exercise, I actually just don't feel like I need the junk food, so I mostly just do without it.
