A study of U.S. adults published in 2016 by Mayo Clinic Proceedings found that 38% of U.S. adults “consumed a healthy diet,” 10% “had a normal body fat percentage” (5-20% for men and 8-30% for women), 46% “were sufficiently active,” and 72% “did not smoke.” In combination, “only 2.7% of all adults had all 4 healthy lifestyle characteristics.” This study was based on data from 2003-2006 because these datasets provided the only “publically available objectively measured physical activity data (i.e., accelerometry data).”
