Her head and hair are huge. She's like drew Carey who looks like they both need to eat a hamburger

I disagree. She was beautiful before and she's beautiful now. She does look different but I think it's just a matter of others getting used to the change. She is1908 not skinny now, just about the right size for her frame.
I've lost about 30 lbs, a lot less than she lost, and I did it very slowly so it wasn't a shock to anyone around me and my skin had time to catch up. Since we see Yvette in pre-filmed things usually, we don't have that luxury. She also may have lost it quickly and as a result she may look even more at home in her skin in about a year.
She looks healthy and like she did it right. Hope it's a good lifestyle change that sticks for her.

No way!! She looks fabulous very beautiful!!!
