A few years ago I decided to tackle the issue and joined weightwatchers.
I lost 33 lbs in 40 weeks and have kept the weight off.
The beauty of the plan ithat you do not have to cut out any food you particularly like - you merely adjust the portions. Also, it is all very logical. Just make sure you stick to the points and it will work.
The weight came off gradually and, by the time I was at goal weight, I had developed new tastes in food which I have kept. This is important as you do not want to lose the weight and go back to old habits.
It really is worth the effort. There is now way I would ever go back to being overweight. It feels like I have gained years of my life back.
