News: These Are the Best Diets of 2018, Says U.S. News & World Report

The Whole30, Dukan and Keto diets landed at the bottom of the annual list. How did your diet do?

Most Americans are gearing up to take better care of themselves in the new year—focusing on wellness is probably on your own list of resolutions. And for many—an estimated 45 million—that means adopting some sort of diet. To kick off the new year, U.S. News & World Report has released the 2018 Best Diets rankings, its eighth annual assessment of popular diet plans.

To compile this year’s list, U.S. News put together a panel of nutritionists, researchers and physicians specializing in diabetes, diet, nutrition, obesity, food psychology, heart health and weight loss. Each expert scored 40 diets in seven categories, including:

  • How easy it was to follow
  • Its short- or long-term weight loss results
  • Its nutritional completeness
  • Its safety
  • Its potential for preventing or controlling diabetes and heart disease

They found the top diets overall to be the heart-healthy DASH and Mediterranean diets, followed by the plant–based Flexitarian Diet. The Whole30, Dukan and Keto diets came in at the bottom of the rankings, with Keto placing last. The reasons? First, a diet that emphasizes slashing carbs while filling up on fats is very restrictive. Second, Keto may not be a good option for those with diabetes, kidney, heart or liver conditions, or those who are pregnant or want to become pregnant. It was ranked last for safety.

Whether you’re looking to lose weight, consume less meat or eat clean, here’s a breakdown of this year’s diets and how they stack up against one another.

A closer look at the top 3
For the second year in a row, the DASH diet is the number one overall diet. The heart-friendly eating plan aims to lower blood pressure, raise your “good” cholesterol levels (HDL), lower your “bad” cholesterol levels (LDL) and help you control your blood sugar. Foods high in potassium, magnesium and fiber like whole grains and lean proteins are encouraged. The diet also suggests limiting foods that can hurt your heart, like salt, sweets and red meat.

Tied for number one is the Mediterranean diet, another heart-healthy diet that can help you lose weight, improve brain health and help prevent cancer and diabetes. A Mediterranean diet menu is made up of foods like whole grains, legumes, seafood, olive oil and the occasional glass of red wine, but not sweets or red meat (unless it’s a special occasion).

Coming in third is the mostly plant-based Flexitarian Diet. Rather than eliminating meat altogether, the goal of being “flexitarian” is to pack your plate with whole grains, legumes, fruits, veggies and nuts; it's a diet that’s been proven to help you lose weight, and lower your risk of heart disease, diabetes and cancer. While the occasional serving of meat is just fine, sticking to mostly plant-based foods is ideal.

Other best diets by category 
In addition to the best diets overall, U.S. News also ranked the best diets for several different categories. These included certain health conditions, like diabetes, as well as particular goals, like weight loss. Here’s a breakdown of the top three for some of the most popular categories.
