Take advantage of an unfair advantage.

Retraining your body and brain and turning on your fat burning almost seems like an unfair advantage when it’s applied to the sporting environment.

For decades, the brightest minds in the athletic performance nutrition field have had carbs pegged as the ultimate good guy. You have been told that the best way to fuel the active body is through carbohydrates, by consuming extra carbs, before, during, and after exercise. As a result, many of us have been enslaved by an outdated mantra which has pushed us to eat carb-laden food to fuel our performance. This approach robs the human body of the flexibility it craves to switch between different energy systems and ways of producing fuel.

As we have already outlined in our first book What The Fat? consuming a high-carb diet is likely to lead to inflammation and poor health in the long run. For fit people, this is a tragedy. The people who value their health and well-being highly. The people who have done EXACTLY what they have been told have often ended up sick, tired and injured because of a high-carb, low-fat diet.

In this practical guide we present compelling evidence, inspiring real-life stories from very successful athletes, and simple ways to eat Low-Carb, Healthy-Fat. We need you to step outside the square and reset. We will ask you to forget everything you were taught by your old-school sports performance nutritionist and learn how to become the ultimate fat burning athletic machine.

Let the games begin and food give you a competitive edge.

    I just realized that I have reviewed the book ” What the Fast ” in the space for “what the Fat” Still 5 star!!!!!

  2. chris

    This book is simple in its explanation of key topics but deep enough to satisfy a professional or enthusiast. I am a doctor of chiropractic who has lost over 100 lbs. with only dietary, fasting and exercise means…mostly dietary and fasting on Monday and Tuesday as described in your book. My blood sugar issues brought me to the fasting and lchf community. Thank you for your knowledge and encouragement…Chris

      Hi Muhammed, we’ve been approached by a South African publisher, so keep an eye out – no dates yet tho.

    Hi Caryn, I bought the 1st and 3rd books here in SA – what is the possibility of getting this one here as well? Surely the company that brought the other two in can get this one as well – I desperately want this book as well, especially love What the Fast!

      Hi Helene,

      we’re working on this! Glad you love What The Fast! In the meantime you can still order Sports Performance from New Zealand via this website; the price will be calculated in the cart before you pay, so you can check if the postage will be excessive first.

    Hi Caryn
    Is this book available in SA yet?

    • What The Fat?

      Hi Ryan,,Caryn says No unfortunately, we’re still working on an agreement with the first book and SA, but there is an ebook version on Amazon (which you can get to through this website under “buy the ebooks”) and people have ordered it from NZ,

    After I read the WTF (non sports) book, I lost 5kg by accident, some of this was muscle mass (and some was doughnut), and this was because I didn’t understand the application of carbs during intense exercise. I probably depleted my glycogen and lost a little muscle. Since reading this sports performance book it’s cleared up all the confusion I had and adds a nice extra layer on top of the WTF book. Since reading and applying this information I find my mountain biking endurance greatly increased, and I’m gaining lean muscle again, and have a much better understanding of how carbs and fat are consumed during sports.

    I’m so grateful that someone recommended this book to me. Before reading it I couldn’t see how low carb could possibly work with endurance sport. It makes so much sense and I know understand why I’ve struggled using traditional methods (calorie counting etc). I am excited to embrace LCHF and see what benefits it brings me in line with training. The case studies and sample recipes are so helpful; I went out and got the WTF book and this has given me a lot more ideas for food shopping. Thank you!

    *Amazing book, I’m soooo inspired now!! I’m a burnt out mountain biker & triathlete after years of eating the typical coach prescribed high carb so called ‘athletes’ diet!! The stress on my body and inflammation /pain and sickness has near killed me and I had to give up training at the start of this year 🙁
    Seriously this book is gospel and my heart is singing for joy!! Haha I’ve not read the other first book yet (buying today) but have been loosely following the LCHF guidelines over the 1.5 weeks and feel amazing already, I’m always feeling full and no longer feel strapped to the sweet cravings and continual carb top ups & have lost 2kg!
    I’m soo excited to put this into practice and return to a full abundance of energy athlete!! Give me a few years & Watch out NZ ironman!! I’ll be back Lol 😉
