Hi Barry,
Each of us will find whatever works for us to maintain a healthy weight and the method will be as unique as the number of members on this forum.
One thing we do know, is that if you go back to your old ways, you'll be right back here again. Medifast does offer the "Take Shape" maintenance products and program. For some, a combination of Medifast products and regular food may be the answer. Other's may find that after experimenting with different food groups, they can find a combination that works for them. No single path will work for everyone.
As this forum is new, and many of our members haven't reached those crossroads yet, we haven't got too far on this topic in the "Maintenance" section. Nancy has begun covering that in the December Newsletter:

We'll get into it further in the "Maintenance" section here on the forum, as the need arises.
Your weight gain over the weekend could be for a variety of reasons. To speculate on what happened would be just that, and not be of any use to you.
The program was not designed to switch directly to regular food. There's a proper transition period to follow, a maintenance phase, then the switch to a healthy, "balanced" diet. Note the parenthesis around balanced. This is VERY important, as is continuing to get an adequate amount of water. This will be a life long endeavor. Just like improving and succeeding in any other part of life, it takes time, practice, experimenting, and experience. Our modern society has fell short of this the last 50 years and it's about time we begin doing something about it. I cant' think of a more important area of your life to concentrate on though. Nothing much else matters, if we don't have our health.
I suggest you don't worry too much about it at this point and concentrate on getting to a healthy weight again. Once you get your body working like it should again, you may find that with just reasonable, healthy eating habits and moderate exercise, you'll do just find. The body is an amazing thing when it's healthy and working like it was designed.
Keep us posted,
Unca
