Why do the give carbs to kidney patients, why not meat iv's?
They don't always give carbs to kidney patients. It's not required and it's not essential. In fact kidney patients actually do better when carbs are not added to their dialysis solution.
Btw the pancreas shuts down wthout carbs
No. The pancreas secretes insulin when fat and protein are consumed too, just not as much as it does when carbs are consumed. That's a very good thing for low carb dieters.
