@syedlaeeqahmed I am not a medical professional. Usually a person does have a restricted protein because it can strain the kidneys to process everything. Once they start dialysis, more protein is allowed. My sincere suggestion is to check with your father's medical team and get their input. Having health conditions can truly affect us and our energy. My team, at one point, simply told me to eat what appeals to me.

At this point I use homemade protein shakes to help me. Perhaps a review of all his medications with his team may lead to reducing or eliminating a few?
