The Mediterranean Diet is backed by research, according to Registered Dietician Meagan Moyer.
ATLANTA -- With bathing suit season approaching, more people are paying more attention to their weight and diet.
Registered Dietician Meagan Moyer of the Emory Bariatric Center talked to 11Alive's Jennifer Leslie about five of today's top diet trends.
"I do like Weight Watchers because it's all about balance and points," Moyer said. "Another big component about Weight Watchers that's great is the support system people have when they follow it. Hands-down, the more support someone has when they're on a diet, the better they're gonna do."
"A lot of really good research is coming out about the Mediterranean Diet showing it may help prevent many chronic diseases and lead to a longer life. It's less of a diet and more of a lifestyle," Moyer said. "It's based on seasonal food, very few processed food, very plant-based, fruits, vegetables, nuts, olive oil."
Moyer said it must be extra-virgin olive oil.
She said physical activity is key to this diet, as well.
"I like the DASH diet. It's more of a meal plan than a diet," Moyer said. "It actually stands for dieting approaches to stop hypertension."
Moyer said it's similar to the Mediterranean diet.
It was developed by the National Institutes of Health Heart, Blood and Lung Institute.
"It's very plant-based, with fruits, vegetables, whole grains," she added.
The diet includes cutting back on salt, red meats, sweets, added sugars, sugary beverages, alcohol and fats that come from animals. It's rich in potassium, magnesium, calcium, protein and fiber.
"When we think diet, we think deprivation. But the Volumetrics Diet is the opposite of that. Let's eat more but weigh less," Moyer explained. "It's al based on high water content food, so the idea is a lot of water, a lot of fiber. It's going to fill up our stomaches without leaving us wanting more."
It was developed by a nutrition researcher at Penn State.
"I wish the Atkins Diet would go away, but it just won't," Moyer said. "Eating bacon and eggs and steak every day is obviously not a good idea. It's not sustainable."
Moyer said too much protein can damage the kidneys. The diet can also cause irritability and fatigue.
