Type of diet may not make a difference
A study published in Circulation: Cardiovascular Quality and Outcomes has found the long-term impact of several popular diets on weight loss and heart health remains unclear.
The study analyzed clinical trials of four diets – Atkins, South Beach, Weight Watchers and Zone, as well as “usual care”. Usual care refers to traditional methods to promote weight loss – low-fat diets, nutritional counseling, self-help books, etc. In a head-to-head comparison, the researchers found that they all resulted in modest weight loss at one year, but that often the dieters gained back at least some of that weight at two years.
In another head-to-head comparison, the scientists observed no marked differences between Atkins, Weight Watchers, and Zone diets at improving cholesterol, blood pressure, blood sugar levels or other cardiovascular risk factors**.**
The scientists concluded that the data is not sufficient to determine if any of the popular diets is more beneficial than the others for both weight loss and heart health.
