There is no one diet, whether it's a Mediterranean, low-carb or low-fat diet, that is consistently better at helping people manage diabetes, says Stephanie Dunbar, director of nutrition and medical affairs for the American Diabetes Association. She is one of the authors of a new review of the research on diabetes diets published in February's Diabetes Care.

"People need to do what works for them. There are people who do well on a lower-fat diet and others who do well on a lower-carb diet." One thing that helps in keeping blood sugar under control is losing weight, even as little as 5% to 10% of body weight, Dunbar says.
