Always find that not eating makes things feel better, but guess I am not the ideal person to be talking diet/ fasting! On the other hand I am fairly indifferent to food and if I am not prompted don't really bother. How about a day normal and a day on low intake? I am going to try this when my last chick is out of the nest! I have all round better uptake of meds and better mobility on low intake.

I forget whether you have a lot of bradykinesia/akinesia.... for me that is where weight gain takes over....
