Core Tip

Core tip: In the context of type 2 diabetes mellitus (T2DM) prevention programs, only recently has the effect on diet quality been reported. However, no studies have examined the effect on diet of a program designed exclusively for men. This study reports on the dietary outcomes following the self-directed T2DM Prevention Using LifeStyle Education (PULSE) program. Following completion of the PULSE program, men receiving the intervention significantly reduced intake of energy-dense, nutrient-poor foods and portion size. In addition, the intervention group increased overall diet quality and greater variety within healthful food groups.
