Drew Barrymore gave her nutritionist pal Kimberly Snyder a big promotional boost for her new book The Beauty Detox Power by helping her stage a cooking demonstration on Ellen DeGeneres' U.S. TV show on Thursday (02Apr15). Snyder helped the actress lose her baby weight after the birth of both her children. Barrymore said, "She has made my body a temple and healed me of things medicines couldn't. I've lost weight, my skin feels better (and) I have the best immunity I've ever had."
