Excellent information. I'm 35 years out from my kidney transplant. Diet and exercise are key to good health. During 2020 I put on weight because of the quarantine. But this year I've taken most of it off (235 to 200 by 12/31/21 is the goal) with careful attention to portions, lots of vegetables ( I do love salads), fruit and no salt. But you're right. It begins with a shopping list.
