Study says all diets have similar results
Diets may be different, but they all deliver similar results, according to a Canadian study.
Scientists at McMaster University in Ontario collected data on more than 7,000 people who were described as overweight. All of the participants had tried at least one of the following diets: Atkins, South Beach, Nutrisystem, Weight Watchers, Biggest Loser, Zone, Jenny Craig, Volumetrics, Ornish and Rosemary Conley.
The researchers found that after 12 months the people who had followed low-carb and low-fat diets both lost an average of 16 pounds. Additionally, those who limited their carbohydrate intake lost slightly more weight after six months, when compared with those who did not follow a low-carb diet.
The study’s findings did not examine the health issues of the diets beyond weight loss, such as nutritional value or cholesterol or sodium levels.
The differences in dieting results were small, and no specific diet was deemed clearly more effective than the others, researchers said. They said the findings, published in the Journal of the American Medical Association, suggest that it's important to find a diet you like because sticking to one may be more important than the diet itself.
