Weight-Reduction: Does Diet Type Matter?

What You Need to Know: Although there are statistically significant differences between various diets, the differences are not clinically significant. If you are going to diet for weight loss, choose a good one with which you will stick.

Background: In the USA, approximately two-thirds of the population is overweight or obese. It would be best if we could recommend an optimal diet. Here we have many choices: The Atkins diet, the Ornish diet, Zone, South Beach, Jenny Craig, etc.

The Study: Johnston and colleagues performed a meta-analysis (study of a collection of studies) of 48 weight-loss trials (with 7.286 subjects). The authors categorized the diets as low-fat or low-carbohydrate.

Although the researchers found statistically significant differences when comparing the studies, they appear to be of little clinical significance. At the 1 year follow-up mark, those on low-carbohydrate diets had a mean weight loss of 7.99 kilograms, versus 7.27 kg on low-fat diets.
