Hi Venusbirth!
I want to say "Congratulations!" to you for choosing to quit smoking. It's better that you chose to quit smoking first, as it is the more immediate health risk. However, I know for a lot of ex-smokers that the smoking is replaced by eating. One vice for another. It's okay, though! You can move past this, too.
How have you quit smoking? Did you go cold turkey? Are you using a patch? Chewing sugar free gum?
If not the sugar free gum, I'm going to suggest incorporating it. Instead of eating when you aren't smoking, try popping a piece of gum in your mouth. Even if you say to yourself "I can get something to eat in 10 minutes... but first I have to chew this gum." You might find that you aren't hungry after 10 minutes, you just needed to get your mind off of the oral fixation.
You don't need to join a specific program in order to lose weight, but many find it helpful to have group support (like 3FC) in order to keep going. I'm a WW member, and it's the in-person support that keeps me going back. I know a few TOPS (Taking Off the Pounds Sensibly) members around 3FC, and that's a group support club as well.
Maybe you want to take a look at Diet Central for other programs. It's not about what
we feel is best, however, it's all about what's going to work for
you. You know yourself best.
Congratulations on going pilates! You are NOT a fraud. You are a human being, just like the rest of us, and you've made a healthy choice today to attend your pilates class. Go & enjoy it. Come back and tell us how you feel afterwards
Post wherever you're comfortable!
Best of success!
