Instead of wishing for something to happen, why not create a plan to help you slowly work toward achieving those goals? Most people who maintain a healthy weight still have to make healthy food choices and exercise regularly. I don't consider myself to be "skinny", but I am a normal weight- and I work hard for that. I get up early in the morning before my 3 small children to exercise, and I make the choice to give my body foods that are good for it. I love a big piece of chocolate cake just as much as anyone else, and I think treats like that are fine in moderation, but that's not the choice I make on a regular basis. So don't think it's easier for that person next to you who isn't currently struggling with a weight issue. It might take them just as much dedication as it takes you to reach your goals.
Hope that helps,
