Answer: Children are more likely to follow the advice of parents and physicians who lead by example.
In the 1970's physicians finally committed to getting people to stop smoking, an effort that was effective because they themselves also quit smoking. We know that leading by example works: when we tell our patients about how we exercise and eat healthy, they're more likely to follow our advice.1
The same seems to be true for parenting as well, at least in terms of diet and exercise. In a study of 100 overweight teenagers, researchers found that the way their parents behaved had more influence on the teens' diet and exercise habits than what their parents said.2
The Research
The participants were recruited from 8 public schools in Poland. With their parents' permission, at the start of the study the study authors asked the students what they knew of their parents' diet and exercise habits, asking them if their parents ate enough fruits and vegetables, ate healthy meals, and if they exercised regularly. The parents themselves were not interviewed—the researchers were only interested in what the students believed about their parents' behavior. The authors also asked if and how often the teens' parents told them to eat less or try to lose weight.
The teens were also asked how often, in the previous 2 weeks, they had exercised and how many portions of fruits and vegetables they had consumed.
The authors asked the same questions again 2 months later, and once again 13 months after that. At the start and end of the study the students' height and weight were measured.
The Results
Those students who reported that their parents ate better and exercised more frequently were more likely themselves to eat more healthfully and exercise—so much so that their body mass index fell over the course of the study. What did not have an effect on the kids' behaviors, however, was parents' putting pressure on their kids to lose weight or eat less.
What’s The “Take Home”?
The authors note that this study has some limitations: all of the participants were white and the study only lasted 15 months in all. That said, it's still a good reason to maintain your own healthy lifestyle: by eating well and exercising, you're not only taking care of your own health, you're probably helping your kids do the same.
