A glimpse at Jeff Halevy's 24-hour diet shows how occasional indulgences can easily fit into a healthy lifestyle. In between his three nutrient-rich meals, Halevy snacks on treats like fat-free pudding and good-in-moderation guac. The behavioral health and fitness expert and CEO of Halevy Life in New York also understands the importance of simple, nutritious meals for busy nine-to-fivers; he prepares low-fat dinners like grilled chicken and broccoli to accommodate his own schedule.
