Hi Connie,
I am about 1-1/2 years post treatment, and in my case eating just doesn't hold the interest it used to. I'm not really sure why.
Like your husband, I like all the same stuff I used to eat, but have no great interest in huge helpings or in snacking (outside of my nightly ice cream ritual).
I think part of it is my teeth. I always (or almost always) brush after eating, which is kind of a pain. Also, I need to have water handy or I'm likely to gag (exascerbated by eating bites that are too big - old habits die hard), so avoid eating at all in some situations.
So, he's not alone.
Best wishes,
Chris
