> Cardio exercise makes you healthy, but it will also make you hungry.

That's what I've noticed, too.

But I've also noticed that it makes me crave different foods than when I sit on my ass all day. So, on average, I tend to actually eat less, because I don't have random cravings in between meals.

I doubt that people who are overweight and sedentary only eat "healthy" meals, only too much.
