Lean In 15 Book Review – No 1 Bestseller

By | June 20, 2016


Lean in 15 book review

Welcome to lean in 15 book review, where going to have an in-depth look into this no 1 bestseller and see exactly why it’s so popular.

There are a lot of books out there that have wild claims, is this just another book destined for the top draw never to be seen again?

Can this weight loss book keep its promise that you can eat more and still lose weight?

You may have tried many books before such as Paleo or the Atkins diet and found that there just too hard to keep up, well there may be light at the end of the tunnel with this book as there are some tasty treats in these pages, but we will get into that later!

We all know that the hardest part of dieting is the taste of the food so let’s hope this book is different to other books.

Also As a nice treat for you readers, I will give 3 recipes from the book (my personal favorite)

About Lean In 15

This book by Joe Wicks aims to provide you with a whole new way of losing weight, instead of living on a depressing low-calorie diet that is super hard to get through the day and you inevitably fail to finish the course, Joe is going to show you how to eat more and get better results.

Lean in 15 teaches you to fuel your body right, instead of just “losing weight” on a calorie deficit diet, Joe teaches how to keep lean muscle but lose fat, giving you a better healthy life and body to match.

Combining high-intensity interval training workouts from home and eating the right food at the right time that will ignite your metabolic furnace for greater weight loss even on your exercise rest days.

With 100 15 minute recipes to see you through the 90-day plan that allows you to eat more and exercise less, making it easy to fit this plan into your lifestyle.

If you are looking for intense fat burning then Joe aka the body coach will show you the way through his 217-page fat burning book.

Who Is Joe Wicks


Joe started this journey back in 2014 by posting a video on Instagram (crazy how social media can start something off)

Joe says “it all started as a bit of fun in his kitchen” he just wanted to share simple recipes to help people get lean.

At the time, Instagram would only allow 15-second clips and all his meals was made in 15 minutes, naturally the hashtag was #leanin15.

However, this book may have never been published if it wasn’t for Joe having so much fun doing the Instagram videos, some of his mates thought it was stupid and he should get back to doing his personal training and bootcamps.

At first, he wasn’t getting much attention but there was a real tipping point a few months down the line, hundreds and thousands of people were watching his videos and trying them at home and re-sharing.

Joe also says ” I am completely self-taught, so I don’t over complicate my recipes and think people respond well to me as I often post pictures of me eating out and eating treats”

One thing Joe is keen to do is to help people  and move away from diet companies that hold people prisoners,  basically put you have to keep up with their programme as you will no doubt put the weight back on once you finish their plan.

This isn’t the case with Joes book.

My thoughts


I picked up this book myself after seeing people rave about it on Facebook, as always my curiosity just got the better of me and had to buy this book.

The first few opening pages when Joe tells you about himself somehow captures you, you can’t help but feel his passion for generally helping people, sure he likes the money but you have to remember he didn’t start off chasing the money.

It all started by posting his 15 mins meals that he would enjoy throughout the day, I find this massively impressive, there is no agenda there is no buy in subscriptions there is just Joe’s unique way.

Essentially what Joe as done he has taken all the discomforts of exercise and dieting and made it comfortable 15-minute meals who hasn’t got time for that?

Joe has been clever when exercising and chose HIIT, this method of training is well known for the impressive results in a short amount of time.

Like with any review I don’t like to give continuous praise, after looking through the book trying to find something to pull him up on, it was hard but I found something.

In fact, I found two things and it wasn’t easy, I am being really picky, firstly they are all meat dishes so not suitable for vegetarians, secondly all though Joe picks’s the best exercises that will work big muscle groups you may find yourself tiring of these after just a few weeks.

Also, some of his exercises need dumbells to get the most out of them.

However, part from these two flaws Joe does a great job of explaining fats, proteins and carbohydrates.

One thing to note about Lean in 15 is Joe is very realistic, he comes from a fitness background and generally wants to help.

 What Others Think


This book is No 1 bestseller for a reason and wasn’t expecting to find many bad reviews, on amazon UK there has been just under 2000 purchases and it has star rating of 4.7 out 5

Blutnik says, tasty meals and made me less fat

Longtallsharon says, no vegetarian meals

Gemma Freeman says, great book, the guys a legend

Apart from unhappy vegetarians the book is very well received and generally loved for its simplicity and time-saving approach.

Conclusion on Lean In 15


Thank you for reading the lean in 15 book review, I can see why this book is a No 1 bestseller, Joe makes it easy for you to make nutritious meals that will help you lose weight.

At first, it may take you longer than 15 mins to do a meal but honestly, they are really quick especially when you do your favourite a few times.

The only real hang up I have is the exercise section of the book has no real substance or depth, however, the book is aimed at exercise less and eat more.

For the price, you really cant go wrong and at the back of the book, there is a gallery of pictures of people who have had great success.

I am looking forward to trying a lot more recipes and seeing the end result.

    This book looks great for recipes and being a big meat fan it’s certainly something I can do

    Does the recipes really take 15 mins

    1. Steven Varley Post author

      Hi Burt,

      At first it may take you a bit long as your going through step by step but once you pick it up it really does take 15 mins

  2. Dominyka Rauktyte

    This seems like a reallyy good book to start a healthy lifestyle, but i saw some recipes, that includes meat.. Since i don’t eat that, i can only wish about a vegetarian version!

  3. Wendy

    This looks like a really effective diet. One of the things I noticed in the recipes is that he uses lots of real food including full fat (coconut oil and full-fat yogurt). This is great! When you eat fat your body ends up burning more fat. Good Stuff!

    1. Steven Varley Post author

      This book is designed for you to eat more, and proper food which is a refreshing change as most “diets” require you live like a rabbit or eat nothing at all, these simply are not sustainable

  4. Micaela

    Along with the fact that Joe is hot this books sounds great. Perve factor and easy recipes. I’m totally going to try that recipe for banana blueberry oats tomorrow. Yum 🙂

    1. Steven Varley Post author

      Have you seen any of his videos? he’s like Jamie Oliver of the fitness world with his cheeky upbeat character lean in 15 is great and well worth a try

  5. Ryan

    Great review Steve. I’ve used HIIT trainign in the past but never really to lose fat, I liked your take on it.

    These 15 minute recipes seem like the best thing for me personally, with an extremely busy lifestyle it’s important to cut time constraints wherever you can, yeah? I might have to check this out next time I’m on Amazon.

  6. Anthony little

    My wife and I make smoothie every morning, you recepies sounds very exciting have to try it out, every thing this about post is awesome my friend great job thank for Sharing.

  7. Anthony Little

    I’m always looking for good recipes, I really enjoy reading your review finding good trust are hard to come bye. Thank for sharing Keep you in mind

  8. Roger


    Great review!

    I love your enthusiasm, and you certainly communicate that Joe Wicks is both an expert and a heck of a guy!

    I also like that the focus of his book IS on the food. Though I am overweight, I am still recovering from a knee injury from last year (!), and so the HIIT aspect is kind of not so much possible for me right now.

    But I am still eating!

    The recipes you offer are a terrific glimpse into the book, and the ease of preparation.

    So maybe I CAN lose some weight (though I should confess when I first started reading your post I was eating a donut).



    1. Steven Varley Post author

      Hey Roger,

      I would certainly take it easy with your knee, at least for the time being, the recipes in this book are great and I like to think of it as a lifestyle change and not a diet as it’s sustainable.

      Don’t worry about indulging once in a while life is meant to be enjoyed and donut is very enjoyable (just dont eat to many)

  9. Jackie

    Hello Steven
    I’ve not heard of this before and although the recipes sound good (not that I’m any good in the kitchen) I worry about the high intensity exercises.
    I wonder if they are aimed at a particular age group

    1. Steven Varley Post author

      Hi Jackie,

      Lean in 15 is relatively new, it sure has made an impact on social media and best seller as well, the good thing is you don’t need to be good at cooking it is so simple I can’t cook but I can cook these recipes.

      Don’t worry about the exercises the word high intensity can be a scary word, for example, my high intensity may be different than your highest intensity.

      So just do it for what you’re comfortable with but make it challenging, if you sign up to my newsletter there will be exercises coming out monthly.

  10. ToveL

    Hi, Steven

    Loved to read your review about Lean in 15 and Joe Wicks. I use coconut oil in my diet and know how beneficial this oil is for me so these recipes will work very well for me.
    I am not so keen on exercising like the author proposes but I know that if you use a lot of coconut oil in your diet, you will feel full, eat less and don’t gain weight that easily. That’s my way of doing it.
    Thanks for sharing.


    1. Steven Varley Post author

      Hi ToveL,

      The exercises aren’t neccesary if your not keen as the book is all about eating more and exercising less, and to be honest the exercise section of lean in 15 is pretty weak.

  11. Mark

    Great review on lean in 15. I heard about this guy in the local London paper, he’s definitely pleasing a lot of people. I’m on a plant based diet so his meal plan won’t work for me but I’d give his workouts a try. thanks for sharing

    1. Steven Varley Post author

      That’s great that you’re on a diet already, hows it working for you?

      Does this diet have a name would love to look in to it?

  12. David

    It’s hard to trust diets these days so I’m glad to happen across your review.
    I have a skinny frame but some belly fat I’d like to get rid of. But, every time I diet and exercise I lose some belly fat along with muscle. I end up looking scrawny and unhealthy.
    If his plan will allow me to reduce the fat while keeping most of my weight on I’ll give it a try.
    BTW those smoothie recipes looks good!

    1. Steven

      Hi David,

      if you dont want to lose muscle whilst dieting then best do HIIT exercise or body weight exercises if you have no equipment.

      Them smoothie recipes do look good

  13. EllieCommunicates

    Hi, I’ve heard about Lean in 15, but still haven’t tried it.
    I understand that Joe’s program/diet is intended to be done over 90 days, is that right? And what results should we expect if followed correctly?
    You said that Joe suggests HIIT exercises? Do we need to do them every day?
    I think the hardest when following a diet is to make the meals, how much time it takes. If Joe’s meals are as easy to make as you say, I am willing to give this diet a try.
    Please share with us your results.
    All the best

    1. Steven

      It his designed to be done over 90 days the, lean in 15 only has a handful of exercises so if you need some exercise to compliment it send me an email and i can show you.

      the recipes are really quick and you dont need to do the exercieses every day

  14. Sofi

    Hey there!
    I came across the lean in 15 but haven’t had the chance to get a copy to myself, I think I will now!
    Very good review, and I think that it will be a great book to have around specially to prepare the meal during the week when time is more limited. Thank you for the advice!!

  15. Sarah

    Recipes always help when I glance through a wellness and health book like this one. You mentioned it can be difficult if you don’t have dumb bells. I have a kettle bell that I work out with. They’re less expensive than a set of weights and take getting used to, but that could be an option for some people. 15 minutes to do a meal would be SUPER for me with littles running around and dragging out the meal times. Thanks for this review!

  16. Pete

    Great review of the book. I do low carb myself, so I think I could adapt some of the recipes to my own needs. Does this book include nutrition information?

    1. Steven Varley Post author

      unfortunately, it doesn’t have the nutrition info in the book its all done on blind faith, the book and joe’s way is to move away from counting calories and macros and basically eat more

  17. Matt

    I like that Cheeky Fried Rice recipe – It looks really good :P. This book looks pretty good. Hopefully not another “Get lean quick schemes” but I feel optimistic about it. Good review.

    1. Steven Varley Post author

      Its my favourite to i can see this diet sticking for long time as its not really a diet, its more education

  18. Austin

    This looks like a very good book. User friendly while giving helpful tips on how to have a healthier lifestyle. I also like the chicken fried rice recipe that you put on this post as well, made me hungry!

  19. simon watson

    A very positive review indeed my friend and u may just have persuaded me to buy that, hhmmm I’ll keep u posted as I’m really interested.
