As a kid, I remember sneaking into the fridge and taking my mom's starch-blocker pills. Didn't seem to help, though.
My most successful diet as a teen was the 'performance anxiety diet'. I was drum major, and every day, I got sick from nerves and couldn't eat at the thought of standing up in front of the band. I did get down to 125lbs, though.
I did slimfast, but I am sure my idea of a 'sensible dinner' was about 3x the size of theirs. Didn't work either.
I did that mayo clinic one, the one where you had to drink grapefruit juice before you ate. I hated grapefruit juice. Strangely enough, it worked until I went off it. I actually like grapefruit juice now.
I tried the throw-up diet on and off for a while. And the laxative diet...
I knew I had a problem then.
WW actually helped me get my eating under control and lose weight, then I started getting sicker the closer I got to goal. Got sick, made goal weight, then couldn't eat anything without getting sick.
Thank goodness my sister tried Atkins! I always thought Atkins was one of those weird unhealthy diets!
She talked me into trying it. I got well doing Atkins, now I doing Neanderthin, and love it!
