Why no coffee or tea with Caffiene BUT you can have Xenadrine?? on CKD??

Yup, what ProteinFiend said. The effects of coffee on sugar cravings are almost certainly due to it's ability to increase insulin resistance, but if you aren't eating carbs to begin with, it can't have this effect. So coffee+donuts is bad, but coffee plus keto is good.
