I wouldn't recommend giving everything up the one time. This makes the dieting even harder!! Instead, I recommend aiming for "healthy living". So eat healthier and exercise more. If you try to cut everything out, you will feel deprived and want to give up (or I know I did). I still have my diet pepsi when I want it, and if I want a candy, i let myself have it. I just have learned to do it in moderation. Also, I found that I couldnt give up my bread. Instead, for pasta, I just have changed from white to whole wheat.
The weight is coming off slow... like 14 pounds in 4 weeks; however, I feel a lot better than I did a month ago!!
Just a little suggestion
