in 2013 amen co-authored with pastor rick warren "the daniel plan: 40 days to a healthier life," on "how to lead a healthy life". amen was one of the people— others included mark hyman and mehmet oz—that warren recruited to help devise the program . warren encouraged adoption of the plan by all member churches in his network of saddleback churches. according to janice norris, "the daniel plan is ... more than a diet. it is a lifestyle program based on biblical principles and five essential components: food, fitness, focus, faith, and friends." amen, warren, and hyman appeared on the television show "the view" to discuss the daniel plan, and 3,000 people came to a rally at saddleback church in lake forest, california, to hear the three talk about the plan.
