U.S. News evaluated and ranked 20 diets with input from a panel of health experts. They looked at whether or not a diet was easy to follow, nutritious, safe, effective for weight loss, and effective against diabetes and heart disease.
According to U.S. News, the top rated diet was the U.S. government-endorsed Dietary Approaches to Stop Hypertension (DASH). Other high-ranking diets included the Mediterranean Diet, the TLC diet, Weight Watchers, and the Mayo Clinic diet.
Oddly, however, the Paleo diet ranked lowest of the 20 not because it was a poor diet, but because they didn't believe it was possible to find the appropriate foods in the modern era!
Another recent study supports the notion that when it comes to your weight, the quality of your food is paramount.
In a comprehensive study, researchers determined exactly how much weight gain is associated with the consumption of certain foods. The worst offenders were potato chips, which caused more weight gain per serving than any other food, the study found. The best food was found to be yogurt.
According to Time Magazine:
"It matters, of course, how many total calories you take in each day, but the authors say the age-old advice simply to 'eat less and exercise more' may be naïve. To control weight over the long term -- adults gain about a pound a year on average -- the study suggests that people benefit more by focusing on eating right, rather than less."
