Sure but that’s not a problem solvable at an individual level— we need structural changes to help keep kids healthy. Long recess, more (non-traumatic) physical education, healthy school lunches, walkable cities, shorter workdays, regulations on advertising sugary foods to kids, reduction in environmental toxins that contribute to asthma, safe bike infrastructure, subsidies on fresh fruits and vegetables, etc. all would have an impact. But right now most obesity public health policy seems to “eat fewer calories dummy” followed up by a shocked pikachu face when that seems to have no impact.
