Hi, I agree with Suzanne, that maintenance is the difficult part of dieting, and too often the lost weight comes back with a vengeance! Losing the weight, on Medifast(I am on this plan) is really so easy. But, once past transition, it is very easy to gain some or all of the weight back and that is one reason why Medifast recommends a maintenance program, using their products along with regular food. And, this is why, we see many re-starters.
I plan to join WW when I have reached my goal. I have no intention of eating Medifast supplements for the rest of my life, as is suggested. That ought to tell us something about regaining lost weight, huh?! Companies make money off of the dieting consumer, so why should their diet plans end! After weight loss goals are reached, they continue to suggest their products for, what I assume, is a lifetime.
With WW, there will be good portion control, nothing is forbidden in moderation, and it seems like the logical step to take after weight goals have been reached. Finance-wise, WW makes more sense, as Medifast is expensive. And, attending monthly meetings will hopefully add to maintenance. I am one who has to see weight come off at a decent pace. Four pounds a month and I would lose motivation on other programs. But, this is just me. No matter what plan one chooses, I wish everyone on this forum, wonderful success in attaining their goals.
