                                Research has debunked the popular myth that it takes 21 days to form a new habit, with a landmark 2009 study finding the average time is closer to 66 days, ranging from 18 to 254 days for a behavior to become automatic. This wide variability holds true for creating good eating habits, which depend far more on individual consistency and environmental design than on a strict calendar deadline.
