I guess eating and fasting during a 24-hour period is not considered Intermittent Fasting if it's done daily as a regular schedule...day-in and day-out.
If the week of eating is broken-up with a couple of Fasting Days, then that would be IF.
Probably the healthiest way to eat and fast is to do the same thing everyday for an extended period of time....be it eating and/or fasting.
This also depends on your Body Image. I like the world-class Marathon Runners. They're small men....averaging 5'6" and 117 pounds. But they can run all day at 5 min/mi pace......WY
