They aren't saying you can out run a bad diet- parent post I thought made themselves exceedingly clear that they suggest exercise as a way to help someone eat healthier because of its effects on cravings/etc. The two things can work together.

I say this as someone that knows how much easier it is to cut calories than to burn them- but I know if I was a bit more active, it would be easier to cut the calories

I don't understand how most replies to multiple of parent's posts keep completely missing their point. It's like the replies didn't even read the post they're replying to
