I just read about this diet which is new to me and the name of this diet is Pritikin Diest. On further research, below is what I learnt about this diet.
The Pritikin diet is a low fat approach to eating. On the Pritikin diet, your eat large amounts of fruit, vegetables and grains. Some animal protein is allowed in the Pritikin diet. All fat eaten must be at 10% of your total daily intake.
The Pritikin diet was originally developed in the 1950's by Nathaniel Pritikin. In 1976 Nathaniel Pritikin open the Pritikin Longevity Center in Aventura, Fl. For 33 years people from all over the world have come to stay at the Pritikin Logevity Center for an intensive one week program. During their they start Pritikin diet program. The Pritikin diet is also available as a book. The book is called The Pritikin Edge. This book can be bought at major book stores as well as on Pritikin Diet website You can also order precooked foods to help you jump start the PritikinDiet on the website. The Pritikin diet is a common sense approach to eating. You must exercise to be successful.
Off course Pritikin diet is not the only diet there are others like 4 Day Diet and the South Beach Diet. However all diest show be complemented with exercise.

Here is more about Pritikin Diet
Everyone who's ever thought about going on a diet has at least heard of The Pritikin Approach: a low-fat diet, not vegetarian, but largely based on vegetables, grains and fruits. Fat in the diet accounts for a mere 10%. Since 1976, more than 70,000 people have spent time at the Pritikin Longevity Centers learning how to eat healthy, prepare low-fat meals and snacks, and incorporate exercise and stress-reduction techniques into their lives. Several books by Nathan Pritikin carried the message of the Pritikin approach to the masses. It was an approach designed largely to promote well-being by lowering cholesterol and helping diabetics normalize their blood sugar without taking insulin. That people lost weight was an added plus.
Now his son, Robert, has taken over and tweaked the concept. The same plant-based foods of the original are the staples of his diet, and the fat content of the regimen is still about as low as you can go. But Robert's latest book, The Pritikin Principle (following The New Pritikin Program and The Pritikin Weight Loss Breakthrough) focuses on something he calls The Calorie Density Solution.
He claims the concern is not calories but rather how dense they are in any given food. Fill up on foods that have relatively few calories per pound and you will lose the "excess body fat that threatens your health and longevity."
Choosing foods that are not "calorie dense," such as apples and oatmeal, promises to "give you the freedom to eat until you are full and never limit your portions or be hungry in order to lose weight." The higher the caloric density of any given food, the more likely it is to cause weight gain, because you will consume more calories to feel full than if you choose foods with a lower caloric density. A pound of broccoli, for instance, has only 130 calories (that's raw and unbuttered, of course) but a pound of chocolate chip cookies has 2,140 calories. You get the drift -- broccoli, good; chocolate chip cookies, bad.
