I was diagnosed pre-D about a month ago, and have been following the blood sugar diet for the past three weeks. So far I've lost 11lbs, significantly reduced my waistline, blood sugar and cholesterol levels, feel fitter and healthier than I've done for the past 30 years and sleep like a baby. No cravings, either, after the first couple of days - apart from an occasional yearning for a piece of buttered white toast...
The point about Mosley's diet is that - despite some of the views above - it
doesn't advocate a perpetual regime of 800 calories per day. The clue's in the title - 'The
8-week Blood Sugar Diet'. For most people, that period is long enough to reduce their blood sugar levels to near-enough normal and readjust their natural insulin production. It's a kick-start, in other words, and Mosley is at pains to point that out. Along with details of the research that led to the diet, the main thrust of the book advocates lifestyle changes (eg more exercise, less alcohol and high-carb foods) and the adoption of a 'Mediterranean' diet (not pasta and pizza, though).
Mosley trained as a doctor, is married to a GP and has a son at medical school, so is no amateur in this field. He also has a lot of backing from highly respected medics with considerably more expertise in the treatment of diabetes and obesity than your average celebrity diet guru or mail-order 'nutritionist'. The main strength, though, is that the recommendations in the book are evidence-based - ie they've proved effective for thousands of people and have been subjected to extensive research study by people who really do know what they're talking about, medically speaking.
The diet isn't for everyone - as Mosley is careful to point out (he offers alternatives) - but then, no diet is. For those who are interested, there's a website that contains most of the ideas from the book, along with a load of recipes (which, judging by those I've tried, are excellent) at
