A new study by the University of Minnesota reveals that parents, who tell their children to finish everything on their plates are 'fueling obesity'. Researcher Katie Loth says, ''I was surprised at some of the parent behaviors, like feeling that their children should clean their plates and not waste food. In the 1950s, cleaning your plate meant something different. Portion sizes have got bigger over time, and if you encourage kids to rely on environmental indicators, like how much food is on their plates or the time of day, they'll lose the ability to rely on internal cues to know whether they're hungry or full. Fathers are more likely to insist on clean plates than mothers and are more likely to pressurize sons. Teenage boys were more likely to be put under pressure to finish their food than teenage girls.''
