I am still successfully losing. I am down 13-1/2 pounds in 10 weeks. This is a big milestone for me, and I think it has been the switch to Medifast that has done it.
alinnell, why not follow the actual Medifast Transition Plan? It might work better for you than trying to do it on your own.
As you all know by now, I'm not able to eat the Medifast foods because of an intolerance for protein isolates. But, I was doing so well on it before I found this out, that I didn't want to just go back to doing nothing and regaining. So, I devised substitutes--food combinations that were close to the Medifast Meal calorie level and nutrition profile. I have to say, it doesn't work as well as I think the Medifast Meals would, but I am still losing.
If you are someone who is having trouble because your old way of losing just no longer works, for whatever reason (including not being able to stay on it), I would suggest finding a different approach--maybe something you ordinarily wouldn't consider--as long as it is reasonable. (Obviously I don't mean the grapefruit diet...
