Over a three-year period, approximately 550 men (ages 50 to 75) diagnosed with prediabetes who were also overweight or obese received five to seven group counseling sessions on healthy eating habits. The men also had access to a web portal that provided online materials every month and a discussion platform for participants. A second, control group of 345 otherwise similar men only received one counseling session on healthy lifestyle, at the study’s start.
