If you’ve been reading the diet news recently, you’ll have seen a huge amount of hubbub over intermittent fasting (IF), the dietary regimen where, shockingly, you eat less food.

That’s an oversimplification of the diet, obviously, but also in essence what you do — intermittent fasting diets restrict your eating by making you eat only at certain times or in certain patterns. So, for example, you might skip breakfast and lunch and only eat in an 8-hour window during the evening, or you might fast entirely on certain days of the week.

And, depending on which headlines you read, the diet is either pretty effective and well-liked, or a total waste of time. This is genuinely wonderful, because based on the evidence both of those ideas are right, and they’re also both wrong. Intermittent fasting is the Schroedinger’s cat of dietary interventions, both working and not working at the same time!

Well, kind of. Let’s look at the science.
