Video: Bible Diet Emphasizes Natural Foods

"I would go on these diets, and I would lose weight, and then I would binge eat a bag of potato chips or some chocolate," Nutter said.

She said she found the real diet answer in the pages of a book that held her utmost trust: the Bible.

"I don't have cravings for anything," she said. "Somebody could eat a bag of potato chips in front of me and it wouldn't bother me. Would Jesus eat potato chips? No."

The Bible Diet kit costs $139.99 and contains a video, Bible bars, even prayer cards. The diet preached the benefits of all natural and unprocessed foods, like vegetables and whole grains.

"I make casseroles, but everything is from scratch," Nutter said. "I'll take a steamer and I'll put in red pepper and broccoli and purple onion."

Whole-grain breads are acceptable, and so are fish and chicken.

"The general emphasis is to reduce calories, and any time you reduce calories, you're going to lose weight," said Elisa Margolius, a registered dietitian at Newton-Wellesley Hospital in Newton, Mass.

Margolius likes the general idea of eating healthier and eating fewer processed foods, as long as dieters can stick to the plan.

"The Bible Diet also emphasizes something a lot of fad diets are not emphasizing -- exercise," said Margolius.

Nutter has lost 40 pounds in the two years she's been on the Bible Diet. She has kept the weight off, too. She said it's not just what she's eating, but help from above that has made the difference.

"Say I get upset and something really bothers me, the first inclination would be go and get something out of the fridge, but instead, I thank the God in prayer. And pray about it. And I'm satisfied," she said.

Margolius said dieters should avoid plans that recommend fasting and those that cut out entire food groups, like dairy. Women especially need calcium in their diet.
