Particularly affected would be those reaching their 40s and 50s by 2030, whose obesity prevalence would approach 60%. And 24 million of those added to the obese would be age 60 or older, whose growing numbers are already stretching the healthcare system. The projected worsening of the obesity epidemic would further add to the nation’s medical burden, with an estimated 6-8.5 million additional cases of diabetes and 5.7-7.3 million heart disease and stroke patients.
