Well, it just so happens that Tyra was part of my motivation to lose weight. I once read that she was 5' 10" and weighed 150 and it gave me hope that I didn't have to be anorexic to be happy with myself. I think she still looks gorgeous at 161 or whatever the heck her weight is now (a few weeks ago, I was only 3 # shy of her weight. I'm a few more now, but also happy like she apparently is and that's all that matters!)
P.S. For the record, I think she's a bit nutty too. But I think it's great that she is who she is and lives on her own terms. That's something we can all emulate.
