I lost 72 pounds on Jenny Craig in the early 90s. Although I gained all the weight back and then some, it wasn't until many years after I left the JC program and got a desk job instead of the retail jobs I'd previously worked; I was able to maintain it for nearly five years. The JC food was fairly tasty as frozen/packaged food goes; I did get a little bored with it after a few months, but I never suffered. The center offered more frills than I ever took advantage of--classes on maintenance, support group meetings, cooking lessons, and so forth. My counselor was awesome.
In fact, if I were to win the lottery, I'd probably head right back to Jenny, but barring that, there just aren't funds available for it. So calorie-counting I shall go!
Rather than continue to beat myself up about having to re-lose all that "post-Jenny" weight, I'm looking at it as a valuable learning experience. JC did teach me a lot about what works for me and what doesn't, so I'm glad to have that experience to call upon now that I'm trying a different road to Rome.
