I am 5 feet 10 inches tall and weigh in at around 200 pounds, I am certainly over weight but I don't know if I qualify as obese. I eat whatever I want and as much as I can, but I always am careful not to fill up my stomach completely, experience has taught me that you just end up having a bad time if you do that. But I am OK with how I am, overweight by a small margin, a relatively small pot belly, so I guess I am like I am because it is my choice.
But I do take care of walking at least 4-5 miles every day. I think that is what keeps my weight constant.
