This can be a dangerous advice; there is a risk when you talk about a complex illness and give specific advise. For me exercise and eating ok is good enough but that is not true for everyone so I try not to give those advice as a solution.
I wanted to refute that eating when hungry is ideal, it lead me to eating more often every day, eventually I was eating huge portions every 2 hours which resulted in insulin resistance.
And you did refute that. It's not something the comment you responded to stated or implied but it's better to be clear about it.
Sorry to hear about your health troubles and I hope that you are on the path to recovery.
