I've been on this eating plan for a month. I've lost weight but, more importantly, my relationship to food has dramatically changed for the first time in my adult life (except when I was pregnant.)

The guilt that comes from eating, especially indulging, is gone. Why? Because 2 days a week I 'invest' in eating >500 calories. This allows my body to heal and decrease inflammation while, mentally, I learn not to panic when I feel a hunger pang. Some fast days are easier than others. But even at th
This is the diet that makes the most sense to me. I did something like this at one point, having one very low calorie day and one "all out" day and then the rest of the days pretty reasonable in order to maintain weight. I'm a binger at heart, so a restrictive diet for months on end will NEVER work for me. Having a couple of fast days a week is so flexible, because you can work around social events and well, just life. I'm glad there is science to back it up, but I'd do it anyway.
Bought this on a whim because it sounded intriguing, and read it in one sitting. I haven't seen the Horizon programme that prompted Kate Harrison to write this book, but she's done a good job of selling this "diet" to me, so much so hat I'm going to try it for a month and see how it goes!

I've spent most of my adult life dieting, and normally lose half a stone and gain ten pounds. This time I have managed to lose 16lbs so far (it was 18 but I gained a bit over Xmas) but I feel like I'm a bit stuc

I was interested in this diet and after reading Harrison's book, I am more interested in adopting some of her ideas and strategies. I found her writing to be honest and encouraging. I liked her approach. It would be great if more people adopted a mindful approach to their diets. I plan to check out her website (

Quick, easy read that provides a good overview of this diet (lifestyle, really). A good introduction, but I found it also very helpful to watch the "Eat, Fast and Live Longer" documentary. This book also connected me to the Facebook group of the same name (set up by the author) which has been hugely supportive and helpful as I begin this way of eating.
Review: This is an unusual review for me as I've never read a 'diet book' before but I'm committed to supporting the authors that I enjoy reading, and having heard Kate Harrison talk about this book late last year, I thought I'd give it a go. I haven't enough of the diet to review that as yet but I will post an update on the blog when I can give that a proper review soon. It's a bit scary admitting that you're on a diet but in the interest of reviewing the book, it had to be done.

First of all,

OK but not as good as the book by Dr Moseley and Mimi Spencer - The Fast Diet. I thought that it was purely for a UK audience who know how big a bag of salad is. Where I live we have different sizes of bags of salads. This applies to many other products she mentions.
3 stars for writing style, but I'd give it more for the concept/theory. I hate to fall prey to "diet fads" and the author kind of makes this sound faddish, I guess. Besides this book I've done more research on Intermittent Fasting (IF) and I'm liking the ideas behind it, and will give it a try. The book gives good tips for fast days, as well as a nice chart with foods/nutrient information, and some recipe ideas for fast days. Helpful for sure.
This "book" should have been a medium sized Blog post. In fact, the Wikipedia page on the 5:2 diet is only about 200 words long and it is equally informative. It boils down to this: "Don't eat anything for two non-consecutive days of the week. Fasting is hard at first but you'll get over it. Don't be a wuss and you'll be fine."
My first introduction to this hyped diet. Provided some information and I liked how there were finnish products mentioned in the translation. It's mainly information you can get online too and then some stories by people who've tried it.

I think I'm gonna give the diet a go in the summer.
Can't comment on the diet itself, but having sprained my ankle and unable to walk for a day or two (including to the fridge or cupboard) without terrific pain, I'm testing out my first fast day today (so far, so good). As far as the book goes, it's entertaining enough to keep me interested in reading to the end, though sometimes it feels like I'm getting all the information third-hand. Still, the sources quoted seem respectable enough, particularly given the author's journalistic background (and ...more
Excellent diet that I will try out.
Don't feel that I can rate or review this until I've been doing it for at least a month so I can see if it works at all!
I got this book to find out more about intermittent fasting. I've read a lot online about how it works. The book covered the basics and gave more of an idea about one person's journey. I believed that this diet worked well for the author and others quoted. This book made me realise that this is not for me at this time in my life though. I think that is a mark of a balanced book. She is clearly passionate about the subject but can present the negatives. This may be something I revisit and this bo ...more
Honestly, the writing equals about a three star… But the fact that I was inspired enough to go ahead and give it a try (and it was free to borrow with Amazon Prime) bumps it up another star for me. First fast day was not nearly as difficult as I thought it would be! I guess we'll see how it goes from here on out!
Convinced me to give it a go. I liked that she intersperses the informational bits with her personal journey. I just did my first fast day and I am hungry but it is manageable. My mental clarity is already better after one day. Hope that continues. Definitely looking forward to tomorrow's feast.

I enjoyed reading this book.
I first heard of this way of eating on a tv programme last year and this author basically goes over the basics and adds extracts from her own personal journey with this diet.
Not sure that it's for me but it definitely gave me food for thought if you will excuse the pun!
Heather Antoy Stephenson
Decent overview and introduction to fasting, explains the basics and isn't too science heavy for those who don't have an in depth interest. Good little starter book for anyone interested in a healthier way of life. Writing is average, mostly engaging but nothing record breaking. 3.5 stars.
Read the book -now to start fasting! I feel more ready for it now.
The book contained a lot of random meal suggestions (which weren't relevant for me, since I don't live in the UK).
It was not consistent in translating pounds to kg :-/
Too many quotes from random dieting people!
e-book for just $2.99 and I was curious what's so exciting about it, so I got it. It is easy read, and it gave me main ideas about the diet. I watched the BBC documentary on PBS last week, and that really got me interested. Planning on buying dr Mosey's book.
Crap. Poorly written by someone who has no background in medicine or nutrition. My fault for not looking into this title more before purchasing. If I decide to try this diet, I will pick up a title written by someone who knows what they are talking about.

Pants are getting tight again.. Time to investigate a new way of keeping the kgs off. I watched the documentary and was blown away by the many health benefits. Also really curious to try few days of fasting,

An interesting book, but I don't think I will be giving it a go. I did pick up a few interesting facts about how being healthy is determined and it isn't just about what you weigh.
A very interesting book which was extremely easy to read. There is lots of scientific information to back it up too. Definitely worth getting whilst it's only just over £1.
Some interesting ideas in this book, though I'm still not entirely sure of the science behind it. I suppose the proof of the dieting is in the weight loss!!
I don't know if this diet works, but I do know that I am hungry. Can't stand to have this on my 'currently reading' shelf any longer.
Meh. This book has a lot of fluff unless you're really interested in the science and testimonials. If you want the basics just Google it.
Well it might be worth a shot if it helps to avoid Alzheimers and Diabetes. Might be too little, too late for the Alzheimers though!
Becky Black
Easy reading friendly intro to the diet, with plenty of practical advice and resources.
interesting concept, will give it a go if it potentially delays dementia etc
