As for the ideas regarding the pills. I think you have lots of great advice here. If you feel the need for something in addition to the medifast, then try some natural things like green tea with hoodia. I would avoid anything that has miracle claims like this. Medifasts claims of weigh loss come from the balanced nutrition that the program provides in following the plan. This claims weight loss through other means, in addition to exercise (which is always good).
I guess I've tried a number of "miracle" pills that I am always skeptical of these types of things.
I am however, all for supplemental things to assist in proper nutrition.
So, I hope that all of these things that we have all said help in your decision.
Let us know how you are doing.
