Wth an overwhelming array of diets to choose from, it can be difficult to know which one is best. Now, US News & World Report have released their 2016 Best Diet Rankings with the aim of helping millions of Americans achieve a healthier lifestyle.
A panel of health experts - including Dr. Lawrence Cheskin, founder and director of Johns Hopkins Weight Management Center in Baltimore, MD, and Kathie Beales, associate professor in the Division of Nutrition at the University of Utah - was enrolled by US News & World Report to review and rank 38 of the most popular diets.
Each diet was scored using seven criteria, including short- and long-term weight loss, nutrition, safety and ease of compliance. These ratings were used to rank each diet in nine categories, including best overall diets, best diabetes diets, best weight-loss diets, best commercial diet plans and easiest diets to follow.
"Our rankings put hard numbers on the belief that no one diet is ideal for everybody, but the best food plans overall are sustainable," notes Angela Haupt, senior editor of US News.
"Besides the rankings and data, each diet has a detailed profile that includes how it works, evidence that supports or refutes its claims and a nutritional snapshot - tools that, along with the advice of a physician or nutritionist, can help consumers invest in diets that suit their lifestyles and further their health and wellness goals."
DASH: the best overall diet
Based on the health experts' ratings, the Dietary Approaches to Stop Hypertension (DASH) diet has been named the best overall diet for the sixth year running, as well as the best diet for healthy eating.
The DASH diet was developed to help lower blood pressure; high blood pressure is a major risk factor for stroke, heart attack and heart disease.
Partly developed by the National Heart, Lung and Blood Institute (NHLBI) - part of the National Institutes of Health (NIH) - the DASH eating plan recommends limiting intake of sweets, sugary drinks and foods high in saturated fats, and eating vegetables, fruits, whole grains, fish, poultry, nuts and fat-free or low-fat dairy products.
The health expert panel gave the DASH diet almost full marks for safety and nutrition, though the diet was not ranked highly in terms of weight loss, coming in at number 12.
Just behind the DASH diet were the Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) diet and the Therapeutic Lifestyle Changes (TLC) diet.
Only developed last year, the MIND diet incorporates components of both the Mediterranean diet and DASH diet - with particular focus on consumption of berries rather than all fruits - and last year, researchers found it could reduce the risk of Alzheimer's disease by 35%. The MIND diet was also rated the easiest diet to follow in this year's list.
The TLC diet - aimed at lowering cholesterol and created by the NIH's National Cholesterol Education Program - involves limiting intake of saturated fats and dietary cholesterol, while increasing fiber intake.
Weight Watchers best for weight loss
While the Weight Watchers diet was ranked fourth in best overall diets, it claimed the top spot for the best weight-loss diet, retaining last year's position.
Weight Watchers was founded more than 50 years ago by an American homemaker named Jean Nidetch. Today, it is one of the most popular diets, adopted in more than 30 countries.
The diet operates on a points system; a person is given a daily and weekly points allowance to spend on food. Points allowances are calculated using age, gender, weight and height, and each food is given a points value based on its nutritional values.
Previous research has shown Weight Watchers to be an effective diet for weight loss; a 2011 study reported by MNT, for example, found people referred to Weight Watchers by their doctors lost twice as much weight over 12 months than those on standard weight-loss care.
According to the experts, Weight Watchers "promotes a healthy, balanced approach to eating," and they state that the diet provides adequate nutrients and promotes steady rather than rapid weight loss, which is better for health.
Closely following Weight Watchers for best weight-loss diet is the Health Management Resources (HMR) program, which involves a number of weight-loss programs that individuals can engage in at home or at a clinic. One program involves home delivery of healthy meals and shakes.
Best diets for heart health and diabetes
When it comes to the best heart-healthy diet, the Ornish Diet came out on top - an eating plan developed by Dean Ornish, a professor of medicine at the University of California-San Francisco, in 2007.
The Ornish diet incorporates what is called the "spectrum" - five groups that incorporate different foods. Group one is made up of the healthiest foods, and group five consists of foods high in saturated fats. Dieters are asked to choose where they are in the spectrum and make adjustments based on what they want to achieve, whether it be to lose weight or lower blood pressure.
