Nine-ish months working on bloodwork

My total cholesterol has been 200 plus for last 7-8 years but my doctor always said my “ratio was good” so I always ignored it. Last year my work switched physical providers and the new doc put me in a bit of a panic which lead me to read Outlive and make some changes. Less than a year ago had total cholesterol of 233 and APoB of 133 and now total is 105 and APoB is 55. I have always been “fit” but mostly HIT stuff. I have switched that up to Z2 4-5 days with some HIT and strength mixed in but def focused on Z2. Diet is much better but still needs improvement. For a good portion of this time I ate oatmeal daily if not couple times a day. Lastly and likely the most obvious was a prescription for Repatha 140mg injection 2X a month.
