Tara McLaughlin said she lost 36 pounds over seven months on the Fast Diet, and she said her dress size isn't the only thing that has changed. He said his doctor told him he had to go on medication and if he stayed the course, he'd wind up like the average American in their 60's -- on eight to 10 different medications. Researchers across the country are finding astonishing results from severe calorie restriction, including decreased cancer risk, increased life expectancy and even improved brain function.
Instead of making up for all the lost calories, participants in the study ate just 10 percent more on feed days.
So when Mosley created the Fast Diet, he came up with a human diet plan to see if he could mimic the results he found in American labs. But there are nutrition experts who are concerned that it is too big a leap to go from "patient zero" to a runaway bestseller with derivative books also making waves.
But over the course of two months, Mosley said he lost nearly 20 pounds on his Fast Diet and his overall health improved. Mosley said there is no evidence that fasting leads to eating disorders, but he warned pregnant women, anyone under the age of 20, under-weight people and those who suffer from eating disorders to steer clear of the Fast Diet.

So he embarked on a quest for the scientific fountain of youth and he found tantalizing clues in U.S. Mosley said one scientist showed him research done in rats that showed brain cells could regenerate at a faster rate when the body was fasting, and they are about to start the research on humans.
Mark Mattson, a professor of neuroscience at John Hopkins University in Baltimore, discovered that the body and brain respond to each other in fascinating ways.
Keith Ayoob, an associate professor at Albert Einstein College of Medicine's department of pediatrics and child development, worries about nutritional deficiencies and the prospect of people taking the diet to the extreme.
Fast dieters can eat whatever they want, from cheeseburgers to croissants, in a guilt-free way, the backers of this diet claim.
Those calories can be consumed in one mid-day meal or spread out over the course of the day, but protein and lots of fruits and vegetables are highly recommended. He created the Fast Diet by fasting on two random days of the week, say Monday and Thursday, then he created low-calorie, nutrient dense recipes. Varady compared two fasting groups: one eating high-fat food on their "feed days" and the other eating low-fat foods.
