The Fast Diet is a book that introduces a revolutionary new dietary approach to weight loss. Code named the 5:2 Diet this new approach to intermittent fasting is the creation of the book’s primary author Michael Mosley.

The book, which has 256 pages, educates readers on how to reduce their calorie intake without having to alter their usual dietary habits. This book is a 2015 release and is an updated version of the first installment of the book.

The new version maintains the same dietary approach as the first. However, in the updated version are new concepts, menu plans as well as tips on how to cut down on your calorie intake. To determine whether this is the dietary book for you, below is the fast diet review.

Product Overview

The intermittent fasting approach from Michael Mosley, as presented in the book, is a straightforward calorie reduction strategy. Using this approach, you enjoy five days of regular eating and restrict your food consumption for two days. The two days need to be spaced out during the week. According to its authors, this plan has a tremendous effect on both women and men.

Though the two authors have varying approaches to intermittent fasting, the message is the same. While on normal days, you are free to enjoy whichever meal tickles your fancy. However, the book recommends sticking to a semi-balanced diet.

During your preferred fasting days consume foods that are low on calories. The book suggests a blend of proteins such as lean meat and carbohydrates such as legumes. Alcoholic beverages are completely off the menu during fasting days as per the program contemplated in the Fast Diet.

To satisfy your hunger pangs, the book recommends taking light snacks in between meals. The meals should be two per day, breakfast, and dinner. For the program to yield the desired results, the author’s recommend taking a total of 142 calories during breakfast and 341 calories at dinner time. This brings the total calorie intake per day to 483 calories.

The Michael Mosley Fast Diet

Contained within the book are 20 pages of testimonials and reviews from satisfied clients. The book also has 18 pages of a calorie counter that lists the various foods to consume during fasting days. The foods are presented in 100 grams portions.

Also, there are 10 different menu plans for maximum calorie intake reduction. These ten menu plans are backed up by ten pages of colored pictorial descriptions. The pictures show the two meals that are to be taken during fasting.

In the updated 2015 installment of the book, the authors introduce a number of new concepts. Moreover, the new updated version comes with a psychology section that explores the inter-relation between weight loss and an individual’s psychology. The book also features a new scientific research section by Michael Mosley.

The Michael Mosley Fast Diet book provides a holistic approach to intermittent fasting thanks to its authors. The book’s main author, Michael Mosley is a UK based medical presenter and journalist who is well known for his program dubbed the BBC Horizon Program Eat, Fast, Live Longer.

Michael came up with his radical new approach after being advised by his physician to reduce his calorie intake or risk High Blood pressure. Mosley devised the plan after researching extensively on intermittent fasting on the web.

Mimi Spencer is the co-author of the book, and she is a feature writer for magazines and newspapers. Mimi is the brains behind the practical aspect of Michael’s personal approach to dieting. She created menu plans and charts, which are ideal for women.

The Good & The Bad

The Pros:

  • Contains ten menu plans
  • Introduces a new concept to weight loss and dieting, which is worth a try
  • The language used in the book is straightforward and jargon-free and void of technical terms
  • Help both men and women drastically reduce their calorie intake
  • The authors are both experts in dieting
  • Topped the New York’s Best Selling Diet book
  • Has 256 pages and is thus not large

The Cons:

  • It is not a strategy that can suit everyone specifically not for pregnant women and diabetics
  • It is not ideal dietary plan for a family
  • This program is not ideal for young women
  • Some have criticized it for lacking a long-term solution

Who is The Book For?

The Michael Mosley Fast Diet book introduces a flexible dietary strategy that is not ideal for everyone. As such this strategy works best with a particular group of people.

For starters, diabetics cannot use this program as they require a constant supply of calories. Therefore, prescribing intermittent fasting to diabetics would be injurious to their health.

Additionally, pregnant women cannot use this program as they also require large amounts of calories for them and their unborn babies.

So who is the book for? The author’s target people who are loathe to the idea of formal meal plans. The flexibility of this dietary strategy translates to it being an alternative to formal and prescribed diets and meal plans.

Formal dietary plans are disadvantageous to persons with busy schedules. This is because for the plan to work they need to alter their daily schedules. The intermittent approach conceptualized in the book is a convenient and flexible alternative.

Therefore, this book is for persons who for one reason or another are unable to stick to a formal meal plan, chefs and food lovers who want to lose weight and for anyone else who feels this program can work for them.


One of the major drawbacks of using the Fast Diet book for your dietary needs is that it does not provide a long-term solution to weight gain. This is because fasting is only possible for a particular period. However, this does not mean that the book is useless; on the contrary, the wealth of information contained within its pages will be instrumental to your weight loss strategy.

Furthermore, the book incorporates the perspectives of the two authors. From this fast diet review, it is evident that although this program does not work for everyone it is nonetheless an effective dietary strategy.

  1. Hi Chris,
    It sound to be an interesting program but I would like to know if there is any instruction if you want to combine this with physical exercises? Usually the amount of calories you need is different depending on the amount of exercises you do in a week. Anyway thank for this review was useful to me, keep up the nice work.

    1. Hi Phil,

      To be honest I wouldn’t really advise people to take on drastic lifestyle changing diets at the same time as taking on new exercise. Any form of exercise burns up calories so you must really think hard about how you are going to handle the two ( exercise AND the diet ).

  2. Hi Chris,

    Thank you for this very thorough and honest review. I do find the concept of intermittent fasting quite interesting as it allows to eat as we desire the other days. Therefore it doesn’t affect our habits do much and doesn’t not create so much stress.
    Had a friend who took a little more drastic approach to intermittent fasting, as he didn’t eat anything during a whole day. He told me he was feeling very good when doing that, however I don’t know if I would like to do that as I really like eating.
    I was wondering if you heard of this type of fasting and its potential benefits.


    1. Hi Jean-Pascal

      I don’t really like the sound of your friend’s version of intermittent fasting – sounds very dangerous for the body! No, I can’t say I’ve heard of this type of fasting – other than starving yourself! 🙂

  3. Hey, what a nice review! You really describe this diet nicely and in detail, honest review. Too bad it’s not for pregnant women and a good thing that you said it…my wife just gave birth and I was thiking of showing her…do you have any idea how could i gain weight quick? Im having problem with apetite, I don’t get hungry a lot. Thanks for sharing this, cheers

    1. Well the first thing I would advise is get your body moving more mate – exercise tends to burn up calories and we become a lot hungrier through it. Can I ask if you maybe have an office or computer job? Do you get much exercise?

  4. This diet sounds right up my street. I’ve heard of it and I know a few people who have done it and lost weight. I wonder if the weight can easily be piled back on when you return to normal meals every day. Sammi

    1. Hi Sammi,
      Well diets need a lifestyle change to work long-term, so if you go back to stuffing burgers down your throat I’m afraid the weight will pile back on!

  5. I find the information about this diet very interesting as I think certain people do this without really knowing what they are doing. They just don’t feel like eating for a day or two and then start eating normally again. I suppose the healthier the normal diet is, the more effective this strategy will be. Thanks for sharing this as I feel this is something to look into.

  6. Hello Chris,
    It has become necessary to control our diet for obvious reasons. But the plight of the breast feeding mother must be paramount in this day and age so that she does not think of the babies they have as the cause of their loss of beauty.
    If our mothers will focus on the diets and a little more exercise, they should be good to go when it comes to it.

  7. Hi, interesting diet suggestion. Just out of curiosity have you tried this yourself? If so, how was it? It seems a little too drastic for me, but that doesn’t mean it won’t work. Also I saw it said it’s been criticised as not being good for long-term. Any idea why you couldn’t do this long-term? Not that I’m sure anyone would want to. Thanks for the post.

    1. Hi Jeff,

      Yes I completed this diet with a close friend of mine – we don’t review things we don’t try ourselves first ( we’d only end up promoting a dud! ).

  8. Hi Chris
    A few of my female friends have bought this from Amazon over here in the UK and so far they are happy with it. Of course all diets take time before you see positive results from them but if what they say is true that wont be long.
    I think you are on a winner here Chris so well done you.
    Have a nice day.
    Robert Allan

  9. Hi Chris, thank you for your review on the Fast Diet. Very good. This should be beneficial to everyone, Especially to those who wants to eat every time and every thing and still want to lose weight. This diet helps as you can still have much and lose weight. It is not very restrictive.

    People will take on to the things that gives freedom to an extent. This diet in my estimation does that.

    Thanks for the review. The information is good. Keep up the good work.

  10. Hi Chris, this is good work. It is always interesting to be introduced to new thinking regarding health. This concept makes sense when I think of how our ancestors could have lived in a distant past. Some days they would have lots of food and some days not. In the end, we also get to understand that everything in moderation works, balance is the key 🙂

  11. An easy to understand and informative artical. I must admit I am always very sceptical when it comes to products that offer a fast track method of achieving a goal as rarely do they work. You seem confirm of the content of this book and give that message across clearly.

    You seem to cover all bases here in a well presented blog, well done.

    1. OK thanks for the positive vibe…I suppose! You say that you are very skeptical when it comes to products that offer a fast track method of achieving a goal yet your name suggests you sell sport supplements…

  12. I have heard some great things about the 5:2 diet, and even the respected British nutritionist Patrick Holford recommends it. However, it clearly is not suitable for everyone. Someone I work with tried it and it really didn’t work for her. Instead she now focuses on eating low GL foods and has had far more success with that, and feels a lot better on it, too.

    Have you tried the 5:2 diet yourself?

    1. Hi Marcus,

      My associate ( who wrote this article ) has tried the 5:2 diet but I have not myself. Nice and slim at the moment through exercise so I have no need to attempt it…yet! 🙂

  13. Good review of the fast diet book.
    I like that you went into detail about the pros and cons of this book.
    Unfortunately it would not be suitable for me as I am a Type 1 diabetic,its more of a quick fix way of losing weight but I don’t think it would be a long term solution!
    Just wanted to let you know that your social media icons on the left of the page are obstructing some of your text.
    Maybe it would be a good idea to position them in a different place.

  14. I practice a version of the 5:2 diet. It may not be ideal for everyone, as far as weight loss goes, which is true. But there are other benefits aside from weight loss, which includes cardiovascular and cognitive benefits. I use it occasionally, most of my fat loss efforts comes from lowering refined carbs and sugars.

  15. I found this to be a very interesting and thourough reveiw of a diet I had never even heard of. If I understand correctly you eat breakfast and dinner and skip lunch, then have a snack in between to curb hunger pangs? I know you said this diet would not be for everybody, and I am not sure it would be for me, although I would be interested in reading the book. Would it be possible to take the ideas in the book and make them work for you? The fasting part would be difficult for me as when I am hungry I get tired and sluggush, and often crabby. I also think protion control is a good part of diet and losing weight as well. Does the book talk about that? Thanks again for this review!

    1. I don’t see why not Denise! You can twist most health plans to work into your lifestyle after all!!! 🙂
