If you're serious about losing weight and keeping it off for the rest of your life you need to permanently change the way you eat.
I recommend Reinhard Engles' "The No S Diet". It sounds gimmicky, but the entire "diet" is printed on the front cover and even Engles admits you don't need to buy the book.
