Adults who said they did not watch TV during family mealtimes were 37% less likely to be obese than adults who kept the TV on while eating as a family, according to a survey of 12,842 Ohio residents, reported in the Journal of the Academy of Nutrition and Dietetics in February 2017. The survey also found that when all family meals were home-cooked, adults were 26% less likely to be obese than when no or only some family meals were home-cooked.

The number of family meals survey respondents ate each week had little impact on their obesity rates.
