I'm 55, petite and pear shaped at 5' 3". I was a skinny kid and slim adult & didn't have weight problems until my mid 40's. I've been trying lots of diets since. I'll lose about 4 lbs. on most and then move on.
I did the Carbohydrate Addict's Diet (CAD) for 2 1/2 years so that was a success - but I got too tired of it. I did WW for a total of about 2 years & reached success but got so tired of journaling and counting points.
My highest weight was 153 and my last efforts were just eating 5-6 mini meals a day and trying to eat as much fiber as possible and whole wheat products. I was doing good but then went on a vacation to Arizona over New Year's and lost it. Came back binging like crazy on candy and chips (candy is a big weakness). I knew I had to get back on track.
I have never been interested in SBD because of my experience with CAD. I tried doing that again without success. But I recently read something about SBD & thought, hmmmm, that's one I never tried.
I'm almost done with my 1st week of Phase I and doing very well. Unfortunately, I didn't weigh myself before starting because I was too afraid of the damage I did on and after my vacation (after was worse than during my time away). But I think I've already lost 4 lbs. and am close to where I was before I left.
My plans are to stay on Phase I until I reach a goal I've had a difficult time attaining, reaching my mini-goal of 135. I get so close but can't seem to get there. Maybe this will do it. I plan to remain on Phase I up to 3 weeks or until I get to 135, whichever comes first (I'll stay on Phase I at least a full 2 weeks).
I got the book from the library plus a cookbook & I thought, hey, I should check out 3fatchicks again. Last time I was here I was doing a version of Johnson's Up Day Down Day Diet. That did help me but I fell off that one, too.
Since this is close to how I've been eating (before falling off the wagon), I really think I can do this and keep it up long-term. So I hope to be posting here as it helps me stay on track. Sorry this is so long!

! SB is the one that works for me...I hope it works for you too!!!
, Judyyo! Glad to have you back! Love your avatar! What a cutie--is it your dog?
I think a lot of us have similar stories in regards to trying lots of plans with varying success. What I think works best in finding a plan that helps you figure out why the diets haven't worked for you. What makes you fall off plan? Are you picking things that are too restrictive for you? Have you dealt with the food but not with the emotions that may be driving your eating? What can you do this time around to make things work more effectively? You may also find help and great advice in our maintainers' group.
Phase 1 is meant to help you get rid of the cravings. Since you've done this style of eating before, you could easily just do a week of Phase 1 and jump into Phase 2, but if you feel the structure will help you get SBD under your belt, go for 2 weeks. But please don't go longer.
