The Mediterranean diet -- an eating pattern that emulates how people in the Mediterranean region have traditionally eaten, with a focus on foods like olive oil, fish and vegetables -- was named best diet overall for 2022, as well as best diet for healthy eating, easiest diet to follow, best heart-healthy diet, best plant-based diet and best diet for diabetes.
"There's no real surprise why that is," Gretel Schueller, managing editor of U.S. News and World Report, told "Good Morning America." "It's healthy. It's delicious. It's nutritious, and it's really easy to follow."
Overall, the diets that ranked in the top five of this year's list -- Mediterranean, DASH, Flexitarian, MIND, TLC, Mayo Clinic, WW and Volumetrics -- have consistently ranked near the top of U.S. News and World Report's list for the past several years.
In addition to ranking in the top five in overall diets, WW, formerly known as Weight Watchers, also took the top spot in the best weight-loss diet and best diet plan categories. The diet was applauded by U.S. News' panel of experts for providing a "customizable, community-driven, long-term strategy for weight loss."
As in past years, diets that are among the most-searched online -- like the Whole30, Atkins, Dukan and ketogenic diets -- ranked lowest on U.S. News & World Report's list, in large part because of their restrictions.
Here is a breakdown of the top three diets in U.S. News and World Report's 2022 Best Diets Overall ranking.
U.S. News and World Report called the Mediterranean diet a "well-balanced eating plan" and pointed to research that suggests the diet helps prevent some chronic diseases and increases longevity.
The Mediterranean diet emphasizes eating fruits, veggies, whole grains, beans, nuts, legumes, olive oil and flavorful herbs and spices; fish and seafood at least a couple of times a week; and poultry, eggs, cheese and yogurt in moderation, according to U.S. News and World Report.
Tied at number two is the DASH diet, which stands for dietary approaches to stop hypertension, and was originally started by the National Heart, Lung, and Blood Institute (NHLBI) as a diet to help reduce blood pressure.
The plan focuses on fruit, vegetables, whole grain, lean protein and low-fat dairy and eliminates foods high in fat and sugar-sweetened drinks and sweets, according to U.S. News and World Report.
"DASH discourages foods that are high in saturated fats like fatty meats. It's not a restrictive diet, it's nutritionally sound," said Schueller. "There's a tremendous amount of science to back up its effectiveness."
The NHLBI publishes free guides on the plan so you can see if it is right for you.
The flexitarian diet encourages people to try alternative meat options, like tofu, but leaves room for flexibility if you can't quite fully give up meat. The diet was promoted by dietitian Dawn Jackson Blatner in a 2009 book that says you can reap the benefits of a plant-heavy diet even if you eat meat occasionally, according to U.S. News and World Report.
This plant-heavy diet focuses on adding five food groups -- "new meat," fruits and vegetables, whole grains, dairy and sugar and spices -- to your diet, instead of taking foods away.
The "new meat" food group includes tofu, beans, lentils, peas, nuts, seeds and eggs, according to U.S. News and World Report.
"For those who want to sort of be more plant-forward, this allows them to do that while still having their little meat treats when they want them," said Schueller.
The Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) diet, ranked fifth last year, is a hybrid of the top-rated DASH and Mediterranean diets.
The diet focuses on "10 brain-healthy food groups: green leafy vegetables in particular, all other vegetables, nuts, berries, beans, whole grains, fish, poultry, olive oil and wine," according to U.S. News and World Report.
Among the diet's requirements is eating three servings of whole grains, a salad and another vegetable daily, as well as a single glass of wine if desired.
The TLC (Therapeutic Lifestyle Changes) diet was created by the National Institute of Health’s National Cholesterol Education Program with the "goal of cutting cholesterol as part of a heart-healthy eating regimen," according to US News and World Report.
The diet, which moved from up three spots in the Best Overall Diets ranking this year, calls for eating lots of vegetables, fruits and lean meats, and allows for breads and pasta too.
In addition to setting a daily caloric goal, participants aim to cut saturated fat to less than 7% of daily calories and aim to consume no more than 200 milligrams of dietary cholesterol per day, according to U.S. News & World Report.
Mayo Clinic diet
The Mayo Clinic diet focuses on a restructured food pyramid that emphasizes fruits, vegetables and whole grains, according to U.S. News and World Report.
"In general, these foods have low energy density, meaning you can eat more but take in fewer calories," writes U.S. News & World Report. "Think of it this way: For about the same amount of calories you could have a quarter of a Snickers bar or about two cups of broccoli."
The Volumetrics diet is described by U.S. News and World Report as "more of an approach to eating" than a structured diet.
Food is divided into four groups with the goal of eating more of categories one and two (fruits and vegetables, nonfat milk and broth-based soup, grains, low-fat meat, legumes) and less of categories three and four (meat, crackers, cheese, cookies, nuts, butter, oil, candies and chips).
"The point is to learn the Volumetrics philosophy and apply it where you can throughout the day," writes U.S. News and World Report. "See where you can replace a category four item with a category one item, for example."
WW rebranded in 2018 with the new name and a new focus on wellness.
WW's myWW program, launched in 2019, uses details of members' food preferences and lifestyle to match members with one of three ways to follow the WW program, according to the company.
WW also introduced a PersonalPoints Program in November that offers a custom-built plan for each member. In another new addition, WW's Points now account for added sugar, unsaturated fat and fiber, according to U.S. News and World Report.
Tips for incorporating the diets into your life
Maya Feller, a registered dietitian and nutritionist, said the top diets all share one thing in common, that they are easy to follow.
"This is about what you can add to your pattern of eating, rather than what you remove," she said. "It is not restrictive. It's incredibly health-forward, bursting with nutrients and something that everyone can customize to their own palate.'
Feller shared a recipe for each of the top three overall diets.
