Hi K.,
I am currently a Weight Watchers(WW) member who has also done Jenny Craig. I prefer WW for a number of reasons: 1) NO food is off limits - you just stay in the range of the alloted points. Every food has a Points value. 2) Me and my family can eat what I make on Weight Watchers. I don't have to make two meals unless I want to. 3) It's roughly $40 a month for WW(right now they have a get 1 month free offer). It costs about $50-$60 a week for Jenny Craig(after initial start up fees, etc. First week it will cost almost $300). That doesn't include the fresh produce and fruits and dairy that are also needed to supplement the Jenny Craig meals.
The biggest advantage that Jenny Craig has is that you don't have to plan out your meals(except when you purchase the food for the week). With WW, you have to track everything you eat. I don't mind planning my meals or tracking what I eat so that's not a big issue for me, but it is for others.
With both programs, you have a weekly weigh in. WW is in a group setting, which I like because you hear what struggles others may be going through, get meal/snack ideas and you celebrate the losses with the group. With JC, your weigh ins are one-on-one. You can meet with the same consultant or switch out every week. JC also takes your before picture and measures you.
For me, I believe I get more bang for my buck with WW because I'm learning to eat with "real world" food versus with JC you eat their food until you have reached goal and then you gradually start re-introducing yourself to the "real world" again. Some people have just continued to eat only JC meals, but I don't I would have been able to do that sine I have a family of 5 and would not have to have separate meals all of the time.
Well, good luck. This is a tough journey, but you can do it. Not sure where you are, but you can email me if you want an online weight loss partner.
