Hi Wandamc,
I'm 35 and have gained about 80 pounds over the past 7-8 years. During this time, I have tried diets, exercise, etc, but always end up gaining back anything that I lose, and then some.
As you said, the keys to wait loss are eating the right amount of calories (not too many, not too few) and keeping active.
Some of the times that I have attempting losing, I have planned ahead each week, made up meals, doled out portions, etc. Somehow or other, I always ended up bingeing or otherwise ruining my plans.
Last December, I got a flyer from the research department of my health plan. I was lucky enough to get into a research study with Jenny Craig and am on Jenny Direct.
It has been amazing! I started in March and have lost 26 pounds. I am losing slowly and am learning about my triggers. I have also received a lot of support from others on the website, which is where I found out about 3FC!
I think that if portions and meal planning are your weak points, JC would be a great choice for you!
Good luck with whatever you do!
