Well I just started reading Whet Belly, so I don't know what comes later, but I just got through the section referencing schizophrenia, autism and ADHD... (chapter 4, if you want to go back to it). Present it to them in terms of concentration, classmates with behaviour problems, etc. That section really resonated with me because my brother had ADD as a kid, and i see so many kids now being diagnosed. Where is this all coming from?
And just because they aren't fat now doesn't mean it wont happen in the future - it's called being proactive in taking care of your health. Are they children, or teenagers? Has the great hormone hit happened yet? All bets are off then...
