His strategy: Don't deny foods, replace them.

"Some of the highest-quality foods are beautiful heirloom tomatoes and other seasonal produce with some nice spit-roasted chicken. So, for me, it's not about saying no; it's about choosing the right things to eat."

His vice: Work hours.

"I just opened two new restaurants, so initially I couldn't spend as much time at the gym as I would have liked, but now I'm working out more, maybe three or four days a week.” 

His healthy food: Peanut butter and celery.

"Peanut butter and celery is something I could eat all day every day."
