"Intermittent fasting" is just modern lingo for "not eating between meals. Our gluttonous culture demands food all the time. In the past, most people "fasted" from supper in the evening until breakfast {literally Break fast} in the morning. Some other thoughts: dieting is NOT fasting - something I tell my vegan friends at Lent. Plus it's ironic that people who have NO PROBLEM abstaining from food & drink under doctor's orders prior to a surgery balk at the easy Eucharistic fast prior to receiving Communion.
