I've never noticed that my sclera color would fluctuate depending on what I ate. Interesting, I never even thought it would be possible to happen so quickly. I will start observing it throughout the day and see if what I eat effects it in any way. I never had problems digesting fat, I actually eat quite a bit of it with no problems I am aware of (I eat lots of nuts, seeds, avocadoes, olive oil dip, coconut oil etc). I will report if my sclera appears any whiter on the days I eat no fat (like the flush).
How yellow are your eyes, and are they yellow all over or just parts of them? Mine are yellow only on the part of sclera that you can see when my eyes are open, the part that's covered by my lids is white.
BTW the cholesterol doesn't affect my skin, never had acne.
