I signed up for JC back in August, but recently recommitted after a 2 month break (due to travel/work/laziness). I found that without JC, I didn't have the willpower or really the time to maintain a steady weight loss, as I don't cook nor do I like eating the same thing every day. I was 'lucky' enough to have stayed the same weight. I attribute this success to my drive, but also to JC. The results I received from them really reinforced my desire to keep going. Anyway, enough about me.
-Easy to follow, especially for those who are new to dieting, counting calories, etc.
-Weekly weigh in keeps you accountable. Trust me, nothing motivates you more to stay honest when you have a JC coach singing you praise when you lose weight!
-The food is pretty good (I only like the frozen foods, not the meals that you keep in the cupboard.)
-Can get expensive!
-Obv. sometimes the JC food repertoire can get old, especially if you don't like eating the same thing.
-IMHO, not enough Asian food...I'm Asian though. I'm sure others will disagree with me!
As far as the metabolic max program, is that with the gowearfit?
I actually own a gwf (before the mm program) and I cannot recommend it enough. It's also a BIG reason why I've maintained my weight/lost a pound or 2 when I went on a JC break.
Something I have to say though is that JC allows you to have free foods and I don't allow myself that. I count everything that goes into my mouth (I'm a diet extremist, I'm told). My mother, on the other hand, doesn't (and she's been succesful). I think the best way (IMHO) is to count everything, so that you can fully take advantage of your GWF. With JC it's so easy to count calories even though it's technically not a part of your program because they're all listed. When you add those all up and then input that info on your gwf, you see the weight loss from the deficit. It's quite motivating!
On another note: the GWF does NOT have all the JC food in the system, but that's not a problem as you can add them. What is a problem is the fact that some of the calories for the JC food are off in the GWF. I'm a control freak, so I've noticed that. They're only usually off about 10-50 calories, but since I count everything...everything counts!
I hope I've been helpful. I know I kind of rambled a bit. Good luck with JC. I'm certain you'll be able to reach your goal
