The standard BMI range (18.5–24.9) applies through your late forties. For adults 50 and older, research supports a slightly wider healthy range (20–26.5 BMI), and for those 65+, a range of 21–27 is associated with the best health outcomes — accounting for protective effects of modest extra weight against osteoporosis and illness recovery.
