AC: The Power of Appetite Correction – by Dr. Bert Herring

“Appetite Correction” is an intriguing concept, and so it intrigued us sufficiently to read this book. So what’s it about?

It’s about modifying our response to hunger, and treating it as a messenger to whom we may say “thank you for your opinion” and then do as we already planned to do. And what is that?

Simply, this book is about intermittent fasting, specifically, 19:5 fasting, i.e., fast for 19 hours and eat during a 5hr window each day (the author proposes 5pm–10pm, but honestly, go with what works for you).

During the fasting period, drinking water, or consuming other non insulin-signalling things (e.g. black coffee, black tea, herbal tea, etc) is fine, but not so much as a bite of anything else (nor calorific drinks, e.g. with milk/cream or sugar in, and certainly not sodas, juices, etc).

During the eating period, the idea is to eat at will without restriction (even unhealthy things, if such is your desire) during those 5 hours, with the exception that one should start with something healthy. In other words, you can line up that take-out if you want, but eat a carrot first to break the fast. Or some nuts. Or whatever, but healthy.

The “appetite correction” part of it comes in with how, after a short adjustment period, you will get used to not suffering from hunger during the fasting period, and during the eating period, you will—paradoxically—be more able to practise moderation in your portions.

Most of the book is given over the dealing with psychological difficulties/objections, as well as some social objections, but he does also explain some of the science at hand too (i.e. how intermittent fasting works, on a physiological level). On which note…

The style is on the very light end of pop-science, and unusually, he doesn’t cite any sources for his claims at all. Now, no science that he claimed struck this reviewer as out of the ordinary, but it would have been nice to see a good few pages of bibliography at the back.

Bottom line: this is a super quick-and-easy read that makes a strong (albeit unsourced) case for intermittent fasting. It’s probably best for someone who would like the benefits and needs some persuading, but who is not very interested in delving into the science beyond being content to understand what is explained and put it into practice.
