Hello and welcome to 3FC

You have come to the right place if what you want is understanding concerning that cycle you mentioned. You described it perfectly! I should know..I've experienced it a million times myself over the years, even over the last months. More than anything, I want to break it and I am determined for that to happen. That's why I'm here. You'll find tons of support, motivation, inspiration, and when needed, a "cyber kick" in the rear..
I want to lose at least 50 more lbs myself. I came here 3 yrs ago and with the help of the great "chicks" I met, I was able to lose over 50 lbs. In the last year, I gained back 20+ of that. It's so discouraging to keep losing the same lbs over and over again. Especially when I never reached my original goal the first time I lost.
I will be 43 in March so I know it's only going to get harder the longer I wait. You are smart to get on the right track at your age. You'll be so glad you did.
I post in a thread under "Support Groups". It is called "I need accountability to get back on track". You are welcome to join us if you'd like. If not, I hope you find just the group you need to help you succeed.
Again, Welcome!
Miki
