For years, eating a diet low in fat was said to be the best way to lose weight. A low-fat diet is one in which less than 30 percent of a person’s daily calorie intake comes from fat. Dean Ornish developed one of the most popular low fat diets after years of research on ways to control heart disease. His dietary ideas were first published in the medical journal The Lancet in 1990.
The Ornish diet plan became more popular in 1993 with the release of his book “Eat More, Weigh Less.” Dr. Ornish studied the effects of carbohydrates – one of the most important sources of energy for the body. He found that carbohydrates were not to blame for making people fat. Instead, he said, fat makes people fat. He noted that a baked potato is not high in fat, but it becomes fatty when people add sour cream and butter to it. His diet plan limits daily calories from fat to less than 10 percent, with little to no saturated fat or cholesterol. He also suggested that people get 70 to 75 percent of their calories from complex carbohydrates, and 15 to 20 percent from proteins.
Like other low-fat diets, the Ornish plan suggests that people eat diets high in whole grains, fruits, vegetables, beans and other legumes. The plan advises people to avoid all meat and meat products, and to stay away from oils, nuts and seeds. It does not limit the number of calories people eat. But, eating the foods suggested by the diet plan would reduce the number of calories. The Ornish diet has proved to be effective for many people.
