It included more than 2,000 people with pre-diabetes who were put on a low-calorie, high-protein diet. People with pre-diabetes have high blood sugar but have not developed type 2 diabetes, ABC News reported.
After eight weeks on the diet, all participants had lost about 10 percent of their body weight and had their blood sugar under control, according to the Danish researchers.
But men lost much more body fat than women, had improvements in resting heart rate, lower bad cholesterol and shaved a few inches off their waist, ABC News reported.
Meanwhile, women had decreases in good cholesterol, lean body mass and bone-mineral content, all of which may pose a risk to long-term health.
Both women and men had a decline in inflammatory biomarkers, resulting in improved blood flow, ABC News reported.
"Despite adjusting for the differences in weight loss, it appears that men benefited more from the intervention than women. Whether differences between genders persist in the long-term and whether we will need to design different interventions depending on gender will be interesting to follow," lead author Pia Christensen, from the University of Copenhagen, told ABC News.
About 86 million American adults have pre-diabetes, according to the U.S. Centers for Disease Control and Prevention.
People with pre-diabetes need to understand that they can easily progress to diabetes if they don't make lifestyle changes.
"If you tell people that they don't have diabetes yet, they think 'Oh good.' They take that loophole," Anne Daly, past-president of health care and education for the American Diabetes Association, told ABC News.
"We don't want people to take that loophole," she added.
