NAT'L TV CASTING: Eating well but can't seem to lose the weight?

You swear, you're eating right, you try to move, but--is the weight just not coming off? Do you read labels at the grocery store, cook the healthiest meals you can, do your best to walk a few extra steps, and find yourself wondering why you aren't losing weight (or, worse, why you gain)? Feel like your body kind of sticks to the same shape/size almost no matter what you do? If you'd love to lose some lbs. and you wonder what you're doing wrong, we're a national TV show and we want to hear from you!
