Currently, I am doing the 6wbm program. I for one, like it. Yes, it can be restrictive - no fat, salt, sugar, dairy...but, in my opinion, it's because I didn't restrict these items before, that I have this weight problem now. I started in the middle of June and have dropped 25lbs. (It would have been more but like almost any other program...I took a day off here and there...
Some people have done the caloric count on this program...it doesn't always come out that way...it depends upon what you eat...I for one, tend to eat more veggies (and extra protein here and there) There are "rapid results" meals which may be part of the count mentioned and a "six day mini-makeover"
This part isn't an ad:
Provida (the ones who own(?) the 6WBM plan) has a website with a message forum...go lurk over there and see what they have to say... it's at www.provida.com.
See what they have to say (In the forums) I've noticed here that the posters do not like the program, in fact I've been rather hesitant to post because I was worried about being jumped on for liking the program...but before anyone can make any kind of decision, you should hear from both sides...and after that...it's up to you.
BTW, I was a WW person for years...the problem I had was that WW was too permissive for me...I can have cake and cookies...just count it...well for me, some days when I want a cookie - one isn't enough which leads to one BOX...the 6wbm, the decision is made - NO, I cannot have it - yet. You still need to weigh and measure your foods - there's nothing too radical about the plan...you will need to eat 5 - 6 times per day the amounts are what's recommended on the boxes(!) - for example, a carb serving for me at one meal is 1/2 c of rice...check the pkg, that's what it reads too! You will need to drink 100 oz of water daily (Considering what you drink throughout the day now, it only sounds difficult)
Anyway, good luck in whatever you decide...
