Are you looking to lose weight this year?

This list of the worst and best diets for 2020 may help you achieve your New Year’s resolution.

For the third year in a row, the well-researched Mediterranean diet KO’d the competition to win gold in US News and World Report’s 2020 ranking of best diets.

“The hallmarks of a ‘best’ diet include balance, maintainability, palatability, family-friendliness, sustainability, along with healthfulness. The Mediterranean diet gets checkmarks in all of those boxes,” said Yale University Prevention Research Center founding director Dr. David Katz, who was one of 25 judges on the U.S. News and World Report panel.

The diet focuses on eating less red meat, sugar and saturated fat and more Omega-3-rich fish and olive oil. Red wine can be enjoyed in moderation and socializing with friends and family during meals is part of the prescription.

“It’s no surprise that the Mediterranean diet remains the No. 1 best diet overall,” said nutritionist Lisa Drayer, a CNN contributor. “It’s easy to follow and offers a healthy eating lifestyle. ”

Meals from the sunny Mediterranean have been linked to stronger bones, a healthier heart, a lower risk of dementia and breast cancer, and longer life, along with a reduced risk for diabetes and high blood pressure.

Top honors

Following closely behind the Mediterranean diet were the respected DASH, Flexitarian, WW (also known as Weight Watchers) and MIND diets. Their high rankings are a trend in the report’s results each year.

The DASH diet is often recommended to lower blood pressure. Its premise is simple: Eat more veggies, fruits and low-fat dairy foods while cutting way back on any food high in saturated fat, and limit your intake of salt.

Studies have shown following this diet can reduce blood pressure in a matter of weeks.

The flexitarian diet tied with the DASH diet for second place because of its emphasis on whole grains, fruits, veggies and plant-based proteins. It’s basically a vegetarian diet that allows the occasional piece of meat or fish, thus making it “flexible.”

The MIND diet is a combination of the Mediterranean and DASH diets that some may find a bit easier to follow, as it requires less fish and fruit. Both MIND, which stands for “Mediterranean-DASH Intervention for Neurodegenerative Delay,” and the Mediterranean diet have been shown to lower the risk of Alzheimer’s disease in studies.

WW came in fourth on the best diet list but took first place in the report’s ranking of best weight loss and commercial weight loss programs. Not only is the diet healthy, the panel said, but it wins top points for stressing the importance of support for dieters.

“We’re interested in diets that have proven staying value — not fad diets that are here today, gone tomorrow,” said Angela Haupt, managing editor of health at U.S. News & World Report. “The diets that perform well are safe, sensible and backed by sound science. That’s going to be consistent from year to year.”

Speaking of the diet trends…

Down for the count

Sure to upset its legions of fans, the trendy keto diet came in next to last in the ranking of 35 diets, just ahead of the obscure Dukan diet.

Both diets aim for “ketosis,” a metabolic state that burns the body’s stores of fat instead of carbohydrates, the body’s natural source of energy. To do that, the diets restrict carb intake to levels nutritionists feel are highly unhealthy as well as completely unsustainable.

In the keto diet, Drayer said, “carbs are limited to about 20 grams per day,” the equivalent of one small banana or apple. Due to the drastic cut in carbs, the diet can cause “headaches, nausea, dizziness and fatigue, particularly in the beginning,” she said, adding that “long-term studies on its effectiveness are lacking.”

In place of carbs, the keto diet emphasizes high levels of protein, fats and dairy, typically full of saturated fat that can contribute to cardiovascular and other chronic diseases.

‘Fast’ weight loss?

First place in the get-rid-of-fat-quick category went to HMR, the Health Management Resources program. It involves purchasing meal replacements from HMR, such as shakes, nutrition bars and multigrain cereals, and adding vegetables and fruits to round out the meals.

Second place went to Optavia, which used to be called Medifast. It, too, wants you to buy and eat many of the company’s pre-packaged products, supplemented by some foods at home.

Both diets could be difficult to follow, Haupt said, “because prepackaged meals tend to get old fast.”

The highly ranked WW tied for third, along with Jenny Craig, which ranked 12th in the best overall diet list.

But the low/no-carb diet Atkins and the keto diet also tied for third place, despite ranking in the deep bottom of other diet categories, such as best diet, most healthy diet and best diets for heart health and diabetes.
