Assuming this is accurate, your lifestyle is not typical. Others trying intermittent fasting and/or vegetarian diet will surely see benefits in blood work.
A) We don’t actually know this, because clinical trials extensive enough to prove it have never been done. B) There’s a lot of variation in humans. Betting that all people will respond the same to any intervention is a bad bet. Case in point: some people survive gunshot wounds to the head.
Sometimes, things are just things. Folks can have high cholesterol with a healthy diet, for example. This is because diet is only part of the picture and a partial method of getting cholesterol. You might just be someone that produces too much (or too little).
Same with blood pressure, for example. You might just have it. or a medicine or stress might be to blame. And with things like vitamin D - you might not ever make enough to be healthy.
Fasting might put you in the hospital! I know a relatively young dude that tried it for religious reasons and wound up hospitalized. He's in his early 30's now, but that was years ago. Some folks cannot tolerate going such periods without eating (diabetics, for instance): They aren't really seeing benefits in blood work.
These aren't really outliers either, but more a reminder that there is variation in humans and we can't make such blanket statements for things like diet. At least not with our current information, doubly so when we consider how much of our research has been tainted by food lobbying and other interests in the last 100 years.
