''We are going to see more children in that [extreme] weight category and in some ways, yes, it's a failure of parents, but it also reflects a failure of society - that we could create a circumstance that would allow and encourage kids to overeat and under-exercise to such an extent that they get to that weight.''
Sort of agree with this in that it is a significant failure of society. Firstly society should give parents the information needed to provide a healthy upbringing, and secondly there is the problem of junk food being highly accepted in society and favorably and ubiquitously shown in things like advertising.
Think the article also mentioned that overweight children may be indicative of lack of care, rarely. Obesity on its own would not be suitable as a reason for... removing a child.
Really... isn't it a problem of parental education? Sounds like fobbing off to me.
