Since I have been using Nutrisystem I have lost 8 pounds. IMHO, the best part of Nutrisystem is the food. All in all, I have been on the diet for 42 days and I have lost 23 lbs and 3 inches off my waist! Protein bars are ideal for those moments you want a nutritious snack on the go. Thank you for the kind words!
There are a few that appear to be mildly effective. This includes Caffeine, Green Tea and Glucomannan (a fiber that can reduce appetite).
However, the results are usually weak and inconsistent and certainly nothing to get excited about. At the end of the day, the only thing that is really proven to help you lose weight is changing your diet.
