Money grubbing hacks lacking intellect and courage? Bro, that one hurts - since you hate science,let me share some anecdotes:
I saw the pandemic firsthand, I was on the medical floors and in the ICUs, watching the floods of scared people, including the smug, arrogant fools who thought it was a hoax, take their last breaths of fresh air before we sedated and tubed them and watched a majority of them slowly die on the ventilator. I was exposed multiple times per day to a potentially lethal virus. Some of my colleagues died from it. My simple intellect managed complicated ventilator settings, vasopressors, and other day to day minutiae of medical care, while other "experts" tried to develop life-saving COVID treatment protocols. My daily social contact and emotional burden was to call families to update them and listen to their cries when I told them their loved ones had passed. Apparently, I don't have courage, but I showed up every day to fight with my patients - regardless of how stupid their beliefs about me, science, or medical experts might be. So, when I was working overtime for days on end, hoping I'd get approved for some hazard pay to compensate me fairly, and dealing with the daily mental trauma of mass death - Where the hell were you, mighty keyboard warrior?
Of course, you sat at home for months on end while reputable source Tucker Carlson brainwashed you to believe - "COVID is HOAX!", "The vaccine implants 5G!", "Spike protein alters DNA", "do your own 'research'", "doctors are liars", "look at the excess mortality". All this from idiots who don't even understand, or in your case, even care about scientific literature at all. You and your peers contributed NOTHING but the take-home message is that physicians are the money grubbing hacks lacking intellect and courage?
It all adds up to this- you're nuts. You live in an alternate reality, my friend. I hope you and the people who think like you can one day get back in touch with actual reality one day. Maybe one day you need a doctor yourself and get some idea of the work we do. Maybe there will be a realization then.
The money grubbing part is always the most interesting part to me because doctors made no extra money from covid vaccines or specific therapies during covid - you realize this right? The only extra pay any of us got was either overtime or hazard pay.
As for the rest of your post - "As a 50 something on/off athlete who likes to eat and drink things he shouldn't" you're one of the last people I would ever take advice from based on anecdotes. You're average health at best and it sounds like literally any diet is an improvement for you. If keto works for you, do keto until your LDL starts pouring from your freakin' eye balls. Nobody cares. The research is available for those who care for it.
