Hi Drina!
Congrats on those 50 lbs so far! Wow
I can give you my experiences with WW. I joined last April, basically because I had NO idea about nutrition, exercise, food intake... anything. I was a clueless person. I knew that I needed to lose weight, and I knew that I was going to need some help to do it. I also was interested in WW, because of the group atmosphere. Having some people to chat with each week who are all going through similar situations with weight loss has definitely helped me out.
I
would worry about me gaining back the weight after stopping meetings, but... that's why I never plan to stop going. Ever. Even when I hit goal. Even when I've been at goal for five years. I've made a commitment to WW, and I plan on going once a week for that 1/2 hour meeting for the rest of my life. It's helped me to lose the weight, it'll help me to keep it off. (I also plan on being a member of 3FC for the rest of my life... so that shows you how much I rely on the group support system!)
WW isn't any more time consuming than most weight loss programs. You do have to track what you eat (they even suggest it on the "Core" program), but all that takes is a moment to jot down what you've eaten or plan to eat on your tracker. Same thing that some people do with calorie counting. The first two weeks are a crash course in how the point system works (if you choose points) but you'll quickly learn the points to your usual foods. You don't
have to cook any differently, but you may want to in order to make foods healthier. There's no right way to cook anything in order for it to be on plan, since the points allow you to eat anything as long as you control the portion size. (I say "anything", but like with any other program, we do somewhat have to watch what it is we eat... can't just consume fries all day!)
Here's pretty much what happens at meetings. I show up about 30 minutes before the meeting starts so that I can get weighed in & settled down. You don't have to show up this early, but this is just something that I like to do... my own time, ya know? People come in and sit down in the room... sometimes people chit-chat, but you're under no obligation. The leader will start the meeting, sometimes they'll ask if anyone has any celebrations or perhaps disappointments they'd like to discuss. (This depends on the leader.) They'll then go over the weekly... "lesson"... for lack of a better word. Basically it's an idea to focus on, related to weight-loss & health... and mental health! For example, this week we talked about the importance of tracking what we eat. How it keeps us accountable, and helps us down the road to figure out what we're doing if we're at a stall in our weight-loss.
The meeting ends, everyone goes on their way

No one need say anything if they don't want. It's often just nice to know that others around you are changing their lives, too. Just like 3FC. We know, because we're all going through it.
At your first meeting, the leader will ask you to stay for an extra 10-15 minutes in order to properly go over the plans. And that way you have some individual time to ask questions/voice concerns etc.
Either way, I've been very happy with the program. I found it upbeat, and doable. Very real life food, too. I didn't want to have to live off of only prepackaged foods, so I don't
Let us know if you have any other questions. We all love to help out!
Best of success!
