If you’re a controlling mom or dad and don’t communicate well with your children, they’re significantly more likely to be obese, according to a Canadian study. Children of authoritarian parents were 30 percent more likely to be obese from ages two to five, and 37 percent more likely to be obese between ages six and 11. Studying four different parenting models, researchers also found that children of permissive parents faced increased risk of obesity. Which parents are not tipping the scales? Authoritative — not authoritarian — parents who clearly explain rules and show affection.
