If you recently decided to try out a new diet, you're in good company. Every year, 45 million Americans go on a diet. That's good news, because more than 70 percent of people in the U.S. are overweight or obese. Unfortunately, some experts say that as little as 5 percent of dieters keep the weight off over the long haul. Why is that? Well, you might be surprised to learn that some of the most popular diets are so difficult to follow that they end up being unsustainable over time. Nothing is more demotivating than constant slip-ups and setbacks, all because your diet is too demanding.
To put the latest diet crazes to the test, U.S. News & World Report evaluated 40 diets with the help of a panel of health experts. The highest-ranked diets had to be easy to follow, nutritious, safe, effective for weight loss and protective against diabetes and heart disease. Not surprisingly, the government-approved DASH (dietary approaches to stop hypertension) diet and the Mediterranean diet tied for first place. But which diets ended up at the bottom? Read on for a list of the ones you need to avoid at all costs.
