I feel for you unclebilly - I really do as I've seen the situation; just a different drug of choice - cigarettes. It is all the same - addictions, just whatever you choose to put in your pie-hole, snort or pill(s).

I cannot think of anything that can be more frustrating than seeing someone you love, willingly do this day-in day-out and all the while know exactly the consequences. Also further you mentioned he has the beginning of Dementia. So now there's an extra layer of sensible reasoning - starting to go out the window.

The only thing when you sit down and calmly speak to him, if he will listen. If you cannot connect his obsession with sugar to something he has lost or grieved in his past as to why, then tell him you love him too much to let this happen. You love him more than he loves himself at the moment. Possibly this may work, other then the next step is removing all those items from his cupboard - then policing the kitchen.
