A fair amount of people have told me they get hungry and eat a lot after using cannabis. This never happened to me, in fact, I used to be 286 pounds and was fat for a long time until I started using cannabis and dropped 95 pounds. I'm not saying this was entirely due to cannabis, but honestly I started working out much harder and began pushing myself a lot better, I've had some of my best exercises stoned. I also no a fair amount of regular users who are in shape or at least skinny, so what's the deal? Personally, I don't think cannabis will cause you to become fat, I think you'd probably be fat regardless.
