Food Anxieties in Autistic Teenagers

Hi

My son (15) experiences extreme food anxieties. For instance when he
arrived at a restaurant yesterday he opened the menu and burst into
tears as he didn’t know how to make the ‘right choice’.

With such food anxiety, and sensitivity to flavours, he’s also overweight.

Does anyone have any general tips? And can anyone recommend any
dieting resources or dieting experts for teenage boys with autism
(relatively high functioning)?

And, what the heck, anyone have any tips on how to get someone like my
son to do more exercise? Or know any PTs who get autism?

Thanks!
