I also followed the weight watcher diet when I wanted to lose some weight prior to being listed for a liver transplant. I was successful during the 7 months that I adhered to the charts and points (this was in 2008). It worked for me because I made a game out of counting and planning my meals! After my transplant, however, I found it to be too restrictive when I needed to regain some muscle mass. At that point I began to follow the Mayo Clinic Diet Plan because it stressed the food groups for a healthy lifestyle. It is my go-to today. I especially like the non-guilt and the tips for breaking bad eating habits and for adding good eating habits.
Here is some information about weight loss basics. It includes information about healthy eating, diet plans, and the Mayo Clinic Diet.
