Hey, my name is Zach and I'm currently a senior in high school. I have tried a bunch of different diets and I would only loose a couple of pounds and then I would be back at my normal weight. I'm going to a weight loss doctor now, who gave me a new diet and exercise program, I started this around 2 months ago. I've already lost 49 pounds (weight 219). My original weight was 268 pounds (height 6'2). My goal is to get somewhere are 195-200 pounds, so thats like 20-25 more pounds to go. Anyway, I have work today (speaking of which, how many calories would I burn in a 7 hour shift, my job consists of lifting foods and putting them on the shelves, I work in the dairy department at my local food market).
