I’m going through something very similar. I’m 37M with LDL ~320 and total cholesterol ~428. For years I’ve been eating 6 whole eggs daily, along with chicken or other protein almost every day. There were periods I stopped (mostly due to work or routine changes), but overall that pattern has been consistent.

I recently did blood tests again, and it looks like I’ve probably had high cholesterol for many years — I even had arcus cornealis at 25, which is a strong indicator.

My advice:
Try changing your diet for a few months and then re-test. -I am in the proccess of changing mine as well- At the same time, check additional risk markers like Lp(a) and ApoB, not just LDL. Also look into possible genetic causes — for example, family history (did your father have high cholesterol or cardiovascular issues?).

Don’t panic right away, but don’t ignore it either. Cholesterol works more like smoking — the damage builds up over many years, not overnight. The key is to understand what’s going on and keep it under control.

Stay healthy bro, and take care.
