autistic daughters limiting diet impacting health

My autistic teenage daughter (not officially diagnosed) has a very limited diet, and this has recently impacted her health significantly. she has been advised to eat more healthy and do exercise. she also has demand avoidence which is making it so diffucult to help her. 

As she has grown up we have tried everything to help in lots of different ways, gentle food introduction, talking about how to be healthy, gentle encouragment to get out for a walk, and she still digs her heels in more.

I feel so exhausted with this. does anyone have any ideas on how to help her?

  • It might be a good idea to let her take the lead. Keep food available so she can decide when to eat. Appeal to her interests; for example, if she likes animals, suggest going for a walk to see some she might enjoy. Or think of anything else that might encourage her to want to go out.
