Well, I've never heard of the med Jardiance. I am on two different meds but unlike the majority of T2 diabetics, I have to be careful what meds I take as they have to work through the liver and not the kidneys as I have a renal transplant.
As to what to eat when you are hungry, my diabetic nurse said rice cakes - lovely chocolate mini rice cakes are my choice as the savoury ones are just to savoury for me as I have stomach ulcers which can flare up if I'm not careful. She also said eggs, or nuts....nothing fills me up, this though, is due to meds I take for the transplant which increase appetite. Rock and hard place come to mind here!! I sometimes make up a small bowl of chopped salad with a little cheese, very little. Or cubed cheese with a small chopped skinned apple and a couple of walnuts
I have to admit to not following a diet even though I need to lose another half stone, and I eat what I want but within moderation. I have reduced sugar, never had it in drinks and so on, so no cake except on special occasions. My downfall is crisps.... cheese... so again, it's in moderation. And I haven't noticed the change in taste of veggies, thankfully.
