We have a group here with a discussion forum specifically for our members who use Weight Watchers.
My 50+ year old mom and my almost 30-year old self have been doing the program since April. I’ve lost 25 pounds, lowered my A1c from the 7s to 6.1, and have better post-prandials because my portion sizes make more sense now. I am a huge fan. My mom (not a diabetic, but short and heavy my whole life) has now lost over 70 pounds - over a quarter of her original body weight. I strongly recommend giving it a shot.
It’s about $40 a month for a weekly membership that includes use of their website and online tools. You can attend meetings or not, attend weigh-ins or not, buy their snacks or not, use their web tools or not. It’s all very customizable.
As for men, my husband has lost about 30 pounds on it, my friend has lost 40+, and my brother has joined the bandwagon now and lost 6 pounds in his first week. My husband also recommends the Abs Diet and a concept called “clean eating.” Our founder here, Manny, has recommended the Zone.
I say it’s wiser to stay away from the programs like Jenny Craig and Nutrisystem that require you to eat their pre-packaged meals. Especially if you eat out regularly. WW just seems easy and sustainable to me.
