The autophagy research that won the 2017 Nobel Peace prize lead to the explosive interest in fasting for cellular health/longevity.
There are now thousands of studies published per year related to fasting and autophagy. IF is a byproduct of this interest.
Autophagy isn’t generally reached with most IF schedules (generally around the 24 hour mark and peaking around the 36 hour mark), but a lot of these studies are measuring other possible benefits and bio markers of IF.
The answer to your question depends on your goals, but if you are fasting because of the hype around longevity I would suggest focusing on 2-3 day fasting periods rather than IF.
