Losing weight takes far more mental as well as physical life changes than simply starving yourself for a certain time frame. If you want to keep the weight off for good you need to focus on lifetime changes. There are many good websites that can help make your tasks easier. Personally I find the Calorie Count website very easy to grasp and full of invaluable info but perhaps you might find something better. But make sure you consult a doctor first before embarking on your weight-loss program. I had to learn the importance of this the hard way...so beware! All the best and hope you reach your goal soon, successfully.
