There is no significant association between fast food consumption or TV viewing and body mass index in adult men aged 20-45.
For men, fast food consumption and TV viewing were not significantly linked to body weight in this study. Other factors may be more relevant for weight management in men.
ModerateRefutesMEDIUM confidence
In men, none of these associations were significant.
