Have you found the "right diet"?

FRESNO, Calif. (KFSN) -- Chances are good you have been on a diet sometime in your life. Finding the "right diet" can be a lifelong mission because new plans seem to pop up every week.

Action News anchor Margot Kim has the results of a new study on the best diets.

Cardiologist Dr. Laurence Sperling has a warning, "you know, beware of fad diets," Sperling said. "Because they are setting you up for failure."

Sperling is a preventive cardiologist and on a national panel of health experts rating the best diets of 2015 based on weight loss, diabetes prevention, heart health, nutrition and long-term compliance. "If you can follow a way of living the majority of the time, those dietary patterns that are most healthy can have sustainable benefits," Sperling said.

The best diet overall was the dash diet: dietary approaches to stop hypertension. It emphasizes fresh fruit and vegetables, low fat dairy and foods low in sodium and high in potassium. "It's as effective as a blood pressure pill," Sperling said.

The panel also gave high marks to the TLC: therapeutic lifestyle change, and the mayo clinic diet. Sperling claims that the best diets have things in common, lots of fruits and vegetables, low-fat animal protein and very little processed food. "You're not eating the same thing all the time," Sperling said.

By the way, boredom is one of the biggest reasons diets fail, "because who wants to eat just meat and cheese all day for the rest of your life," Sperling exclaimed.
