I see why you are thinking that this diet is not as high in protein and fat as it actually is. You are not taking into account that the pellets contain high amounts of both protein and fat or that seeds are also high in proteins and fat.
Birds dying from fatty liver disease, heart disease and kidney disease were the reason that pellets were invented in the first place, they were intended to replace the then current all seed diet that was causing these diseases because they were high in protein and fat. More exactly the birds were picking out their favorite seeds and not eating all of them and these were the seeds with the most protein in them.. The food companies decided to fix this issue by grinding the seeds so that the birds could not pick out their favorite seeds and then they started adding dried vegetables and so on. The thing that they didn't do was to reduce the amount of protein in the pellets with the result that pellets also are high protein food, causing the same issues.
I am just sharing what I know, you can look it up if you want to and I tried to show you this once before and you were rude to me so you use the information as you see fit, or not.
