I saw the Oprah show today, and have to say I wish she wouldn't have interupted the good doctor so often! Just when he would be giving an explanation of something, she would butt in and change the topic to her own concerns.
One thing he did clear up, was that your waist size should be approximately one half of your height number. For us tall gals, that's a relief. At 5' 9", it didn't seem right to me that my waist should be the same size as someone who's only 5 feet tall.
His comment about what happens to men for every 35 pounds they lose was very, very interesting.
