I tried it a few times but it was only so so in my opinion. Then I went on a product called HMR that is used in many hospital based weight reduction programs. Now I liked the tast quite a bit ore than medifast but of course that is such an individual thing. I did well on both but I thought the cost was just too much.
Anything is worth a try I think. What doesn't work for others may just fit you perfectly.
Good luck in your journey.
