Dr. Yoni Freedhoff characterized the media attention around this "don't need breakfast" study as irresponsible and harmful.
Here is Dr. Freedhoff's take on how often you should eat in a day:

And in that vein, I'll say I'd NEVER do IF. Just going from 7am to noon makes me famished. And me being famished = "not good". But that may just be my own messed up body. But I'm with Dr. Freedhoff.... what works for one person may not work for another. Which is why I LOATHE to give nutritional advice. Just because something worked or is working for me doesn't mean that it is the right thing for everyone.
