General query about food. Yellow normal?

I have a gb polyp of size 2.9MM. I am modifying my diet and working out daily as well, in the hope that being healthy will regress the polyp. but daily workout requires a lot of protein, for which i eat 200g chicken breast daily. But in 200g chicken there is 300g cholesterol, which is the rda given by fda. Basically my question is, is it safe to eat chicken daily? And should I avoid cholesterol or fat? If fat, how much of fat should be my daily intake? And within that how much of saturated and unsaturated fat to be taken? Please guide me. And it has been 1 month since it was diagnosed, after how long should i repeat usg? My lft was fine. Also, I observed recently my urine stays pale yellow usually, is that normal? If i drink enough water it does become clear. What's the normal colour? Is yellow normal?
