Im also a qualified Nurse and worked in Paeditric and Paediatric A&E so i know a fair bit about juvenile and child obesity almost certainly a lot more than you do.
Unless your a Paediatric Consultant which i doubt very much
Sorry but whats your 99% based on on ? Which medical book did you read this ?
You are very very wrong anyway, I've dealt with kids who have been overweight in my line of work in a kids hospital.
Maybe you should think before making sweepping statements like that.
