re: Intermittent fasting linked to 91% increase in risk of death from heart disease, study.

I’m a doctor and this is complete bullshite. Go ahead and google “caloric restriction + pubmed” you’ll find several articles proving that operating under a caloric deficit is the only known mechanism behind the attenuation of telomere shortening and aging as a result .
Pubmed is an excellent source of validated clinical data. You’ll find a plethora of data on intermittent fasting and DECREASE in heart disease risk factors.
