The best books on type 2 diabetes: making sense of muddled advice

Illnesses affect families as well as individuals. How would you react to the news that your Dad would soon lose a leg because of type 2 diabetes? Two brothers reacted by setting out to find the hard information about type 2 diabetes. That was tough—but the brothers tracked down the new information that this type of diabetes could be reversed to normal. Then persuading Dad that things had to change was an even greater challenge. The family’s journey, and the remarkable achievement of major weight loss, is brilliantly documented. The insights into the stresses on the family as they support Dad are sublime. Even after decades of dealing with human tragedies as a doctor, this book raised a lump in my throat. Today, Geoff still has two legs. 

First published in 1869, this short account describes the outrageous effects of ‘corpulence’ on the author’s daily life and his search for a solution. Routine advice was ineffective. For a decade he rowed a heavy boat on the river for two hours every morning. He ‘gained muscular vigour but with it a prodigious appetite’ and his weight increased. But eventually he found a doctor who had wise insight. He was advised to avoid foods that were easy to eat in quantity but did not satisfy appetite—bread, butter, beer, milk, sugar, and potatoes. He lost 50 pounds in weight, and over the course of the next four editions of his book, chronicled his long term return of good health. This is a parable for our time. 

Michael Mosley was the one of the first best-selling authors to disseminate the new knowledge about how type 2 diabetes could be put into remission. It is all the more authentic in that he describes his personal battle with rising blood sugar levels. "Once you tip from prediabetes into diabetes you will be slapped on medication faster than you can say 'Coca-Cola'."  And it worth avoiding that fate. This is an eminently readable book which brings you onside with the author—a confident not a teacher. Just look at the section "Sort out your head". It’s the mind and body thing, often overlooked by well-meaning advisers. Just glance down the three sections of the book—The Science, The Diet, The Menus. Where will you start? This book bubbles with well-informed enthusiasm.

Where can you get reliable information on how the body works? Online sites are notoriously unreliable. Most textbooks are unreadable. But here is a book that explains clearly how the body uses food for fuel. This book is not an ‘easy read,’ so don’t curl up with it expecting instant enlightenment. However, if you want to learn the beautiful details of how your body works, go for it. The chapter on "Integration of carbohydrate, fat and protein metabolism in normal daily life" conveys an understanding of how food handling works, and just looking at the diagrams and graphs will take you a long way. And simply reading the "Key learning points" at the start of each chapter will introduce you to the magic of metabolism. 

‘Counting’ calories at every meal is not a recipe for a sane or happy life. But knowing the approximate calorie content of what you regularly eat is certainly wise. This is a look-up book, not a reading book. So—how about the blueberry muffin you have been led to believe is the healthy option? What! 393 calories? But that is about a quarter of the daily calorie requirement for a smaller person. Orange juice? Ah yes, one of my five-a-day—so healthy. But at 90 calories per 250 ml glass it is easy to cut without bothering appetite. Taken in addition to a weight neutral diet, it would cause around six pounds of weight gain in a year. This is a book of information. Information useful for life.
