I've started mine already. I'm using an app where you carefully monitor how much you eat, exercise etc. It's the only thing which keeps me on track. I used it faithfully 2 years ago & lost nearly 2 stones in 8 months. Stopped using the app & weight has crept on again. This time half a stone would make me happy, more would be better.
Nothing better than registering all the calories you eat in a day. App tells you when you're over your limit. I'm not perfect. The odd alcoholic beverage can tip me over my limit, so have to work even harder to shift it in the pool..
