(ABC/WSYR-TV) -- American adults who spend more time preparing meals spend less time exercising, and vice versa, according to a new study.
That study, presented at the Population Association of America meeting, says every 10 additional minutes spent preparing food meant men and women were less likely to exercise 10 extra minutes per day.
The reason for the substitution effect may be related to a lack of free time; the average person spends less than one hour on both exercise and food preparation per day.
The research, based on U.S. Census Bureau data from over 112,000 adults, suggests that advice should be given on how best to budget time devoted to healthy behavior, rather than just telling people they should exercise or eat better.
Because the study only looked at one day's worth of activity, it doesn't take into account the possibility of spending a whole day meal planning to free up time for exercise on other days.
The research was presented at the annual meeting of the Population Association of America in New Orleans.
