To me, an airplane is a great place to diet.

I used to write cookbooks. It was passion to try to bring healthy and fun recipes to people's homes. It was a way to bring my home to theirs.

Prep things in advance so that you don't have to cook everything at the last moment.

One thing I always say is being a great chef today is not enough - you have to be a great businessman.

Now everybody thinks that once you do Top Chef, then 13 weeks later you're a chef. Nobody wants to learn to cook anymore.

For example, you can eat a Caesar salad and say, "Wow, I ate so healthy today." You forget there was a quarter-cup of oil in there, and all the calories are from fat. So it's better if you eat a grilled chicken breast, some steamed brown rice, and a little salad with balsamic vinegar on top.

I grew up so poor in Austria that we never took a vacation with my family.
