I remember reading somewhere (??? Dr. Jason Fung, perhaps?) that losing just one gram of fat from the pancreas can unclog it so the function of insulin producing beta cells is restored, that they aren't burned out or dead, just clogged up with too much fat. So any type of diet which will cause the loss of enough body fat overall to prompt that relatively small loss from the pancreas would likely do the job to restore insulin sensitivity, I assume so long as the pancreas doesn't get re-clogged by regaining fat. So then the question is more of what type of diet is best for body fat loss, least unpleasant hunger-wise, most sustainable long term, etc. For me that's definitely low carb with usually some degree of IF each day. Unlike a few hundred calories of borderline starvation temporary diet, I can sustain what I do indefinitely.

I'm losing weight and reversing my diabetes just fine eating my t-bone steaks, prime rib, bacon etc. Screw liquid diet! Yech!

It still tastes good to me though, so there's a certain amount of entertainment to go with the nourishment.

Except right now - with this nasty head cold, everything tastes like cardboard, with a side of Styrofoam. Quite frankly, with everything having no taste at all, it's hard to eat, except that I am kinda hungry, so I'm not quite forcing myself to eat, but because of the cold, I'm definitely not eating nearly as much as usual.

If I could continue indefinitely to think of food as ONLY something to ease the hunger, perhaps I'd start losing weight again, but the sad thing about it is that as soon as the cold starts to ease up, and my taste buds return to normal, I'm sure my appetite will return to normal.
