From an analysis of more than 1,200 adults, researchers found that a person’s fasting blood glucose levels, fasting insulin levels, or both, were effective for pinpointing which diets were most likely to lead to weight loss.
Such biomarkers were especially effective for determining which diets were best for people with prediabetes and diabetes, the researchers report.
Study co-author Dr. Arne Astrup, head of the Department of Nutrition at the University of Copenhagen in Denmark, and colleagues recently published their findings in the American Journal of Clinical Nutrition.
According to the American Diabetes Association, around 29.1 million people in the United States have diabetes.
Type 2 diabetes is the most common form of the condition, wherein the body is unable to effectively use the hormone insulin, causing high blood glucose levels.
Prediabetes is a condition in which blood glucose levels are higher than normal, but they are not high enough to warrant a diabetes diagnosis. However, people with prediabetes are at significantly greater risk of developing type 2 diabetes than those without prediabetes.
It is estimated that around 86 million people in the U.S. have prediabetes, but around 90 percent are unaware of it.
