Actually doing IF is more like, you have a 6 hour window a day in which you eat, and you eat nothing outside it. For most people that's much more restrictive than "skipping breakfast."

That said, not everyone agrees on the method. Some will skip entire days intermittently, so, this whole discussion is shaky overall, but, definitely agree that "skipping breakfast" is not IF.

Intermittent Fasting (at least as I've seen it practiced) generally lasts more than one meal. Sometimes more than one day. It really flushes out your body, which can sometimes make you feel a whole lot better.

There’s a huge variety of variants of intermittent fasting.
