That’s the result of a new study:
Researchers compared a low-fat, average protein diet, a low-fat, high-protein diet, a high-fat, average-protein diet, and a high-fat, high-protein diet in 811 middle-aged obese people over two years. Each group lost an average of 13 pounds after one year, though slowly started to gain it back in the second year, bringing the average lost after two years to nine pounds.
“In the end, all the diets produced weight loss to the same extent,” said Dr. Frank Sacks, lead author of the study and professor in the department of nutrition at the Harvard School of Public Health. “It really doesn’t matter what particular amounts of fat, carbohydrates or proteins you eat.”
“There really wasn’t magic revealed in the specific composition of the diet,” said Dr. Howard Eisenson, executive director of the Duke Diet and Fitness Center. “I thought their conclusions made sense and jibed with what many of us in the field have long been thinking.”
In addition to weight loss, subjects reduced their risk of heart disease and diabetes and improved their blood pressure.
It makes a lot of sense, really. What matters is the overall amount of energy being added to the system.
Still, the most fit person I know told me he does Atkins when he wants to drop pounds. That has to count for something.
