However, intermittent fasting is part of many religious practices: Islam, Judaism, Christianity, and Hinduism etc. There’s plenty of evidence that it’s probably a relatively healthy practice since none of these groups are in serious trouble health wise. But I also don’t see any huge indication that the practice makes one group healthier or slimmer. But then, for them, that’s not the goal. The goal is having a more intimate experience of the Divine. Fasting is about being alone, reducing the craving of the senses, to allow time for deep contemplation.
