But Dr. Don Colbert, physician and nutritionist, thinks the obesity crisis could be solved if Americans would pause before inhaling a super-sized fast food meal and ask themselves a simple question: "Would Jesus eat this?"
If it's loaded with saturated fats, sugar or artificial ingredients, the answer is no, says Colbert, whose recent book "What Would Jesus Eat?," combines biblical scholarship with conventional dietary wisdom. "The gluttonous spirit is deadly," he said. "I've seen so many diseases related to dietary excess, so why not go back to the owner's manual, the Bible,to see what Jesus ate?"
Jesus essentially ate a Mediterranean diet rich in whole grains, fish, fruit and vegetables and modest amounts of olive oil, meat and wine, Colbert says. Anything the Old Testament blacklists in its dietary prescriptions is out, including shellfish, pork products, horses, camels, birds of prey and other carnivores.
Colbert, a Mississippi native who studied for a year at a Bible college as well as training at medical school, said he wrote the book and its companion, "The What Would Jesus Eat Cook Book," both published by Thomas Nelson, after realizing that many of the fattest Americans are dedicated fundamentalist Christians. "Most people say, `Hey, it's important that I live a Christian life, but my body's not that important,"' he said. "They'll go to heaven, the only problem is, if they neglect their bodies, they'll go to heaven a lot faster."
With six new books in his Bible Cure series set to come out this fall, including books on combating cholesterol, diabetes and thyroid problems through diet and prayer, Colbert's Bible-based diet empire has expanded far beyond his private practice at the Divine Wellness Center in Longwood, Fla.
And Colbert's not the only Christian diet guru urging people to ask what Jesus would eat. Christian advocates of vegetarianism say if Jesus were alive today, he would maintain a plant-based diet out of compassion for animals. Others say Jesus would probably approve of genetically modified food, given his propensity for transforming and multiplying food. "He was clearly not against the need to alter and change food," said Arthur Caplan, chair of the department of medical ethics at the University of Pennsylvania, referring to Jesus' tranformation of water into wine and his multiplying the loaves and fishes.
Although there may be disagreement over what Jesus would choose given the option of a veggie burger, broiled lamb with garbanzo beans, or genetically modified corn on the cob, growing numbers of Christians are looking to the Bible for dietary guidance, hoping that Scripture might succeed where science has failed in inspiring healthy eating habits.
Dr. Stephen Kaufman, co-chair of the Christian Vegetarian Association, said he hopes more Christians will start making faith-based choices about what they eat. "There are a lot of people out there for whom diet is a reflection of their faith," he said. "We're taught to take care of our bodies, the temple of God's spirit, as Paul said."
Kaufman disagrees with Colbert's claim that Jesus would eat meat, arguing that although lamb and red meat may have been acceptable fare in Jesus' time, modern agricultural practices make meat an unhealthy dietary choice, as well as an immoral one. "Before factory farming, the Mediterranean diet that Jesus consumed was probably quite healthy," Kaufman said. "But we live in a different world, and few people get meat and other animal products from healthy, free-roaming, contented animals."
In coining the phrase, "What Would Jesus Eat Today?" in 1999, the Christian Vegetarian Association put forth a Christian argument for abstaining from meat, urging compassion for animals and citing Adam and Eve's vegetarian diet in Eden as the proof that God intended humans to be vegetarian. "We consider a plant-based diet to be a legitimate expression of Christ's witness," Kaufman said, adding that animal welfare is strongly emphasized in the Bible.
Other groups that evoke Jesus to promote vegetarianism go even further. "The biblical evidence that Jesus was a vegetarian is very strong," said Bruce Friedrich, vegan campaign director for the People for the Ethical Treament of Animals, which started holding up Jesus as a dietary role model in 1998 with its controversial slogan "Jesus Was a Vegetarian."
Some, however, say it's impossible to extract a dietary ethic from the New Testament, citing a lack of scriptural evidence. "No diet should invoke Jesus," says Russell Moore, assistant professor of theology at the Southern Baptist Theological Seminary in Louisville, Ky. "He nowhere universalizes his diet any more than he advocates wearing robes and sandals."
