Eating chocolates once in a while is actually good for health. As long as you're not eating one chocolate a day, don't need to worry. Too much of anything can cause you to gain weight(not just chocolates). But if you're really looking into staying away from them then just don't buy chocolates in the first place and avoid places where you'd find chocolates. And please instead of calling it a "diet," why not call it a healthy eating habit, sounds much better doesn't it? :) I'd still suggest working out on a daily basis rather than "dietng" if you want to look and feel great :P
