Stars at the Holidays 2009

"Holidays shouldn't be an excuse to disconnect your brain and your stomach. Enjoy them, but eat and drink sensibly," says David Kirsch, celebrity trainer and nutritionist who has worked with stars like Heidi Klum and Anne Hathaway. "Avoid sugary cocktails and go for a vodka/soda or a glass or two of red wine, drinking plenty of water in between."
