His cancer is gone but he had a Pancreas and Liver transplant two years ago and he is taking major anti rejection drugs that interfere with his appetite. The pancreas is heavily involved in digestion, conversion of carbohydrates to fat, and production of cholesterol that transports fats. His is not working too good any more. His Krebs cycle is not working properly. I think he is not producing fat properly or sufficiently... That's why he took the medical leave of absence. Protein he can do well, fats and carbs? Not so well.
Thanks for your answer, I did not know about the other ailments besides his cancer. Sending prayers up.
