"Intermittent fasting" can mean many things, but what I tried for about a week was where you consume all of your daily calories in an "eating window" ranging from 10-4 hours. So, for example I had it where I was eating from 12pm-8pm, then eating again at 12pm the next day.

It sounded fun, like I could be "allowed" to eat during those times, and it would go well. However, it only took a few days before I would eat less and less hours, and then I decided to do a "fruit only detox"

Long story short, I've learned my lesson, and have realized this behaviour is too addicting even if it is disguised as a "healthy" thing for most/non-ED people.
