My Story - Martina Slajerova

Hi, I'm Martina, the creator of the KetoDiet blog, KetoDiet app & International best selling author

I love food, science, photography and creating new recipes and I am a firm believer in low-carb living and regular exercise. As a science geek, I base my views on valid research and I have first-hand experience of what it is to be on a low-carb diet. Both are reflected on my blog, in my apps and cookbooks.

I currently live in the UK. I hold a degree in Economics and worked in auditing, but I have always been passionate about nutrition and healthy living.

I changed the way I ate in 2011, when I was diagnosed with Hashimoto’s, an autoimmune disease that affects the thyroid. I had no energy, and I found it more and more difficult to maintain a healthy weight.

That’s when I decided to quit sugar, grains, and processed foods, and to start following a whole-foods-based low carb approach to food.

My mission is to help you reach your goals, whether it's your dream weight or simply eating healthy food.

My Bestselling Books

My books will walk you through the guidelines and benefits of the ketogenic diet, and show you how to make more delicious low-carb recipes.

What Experts Say About My Books

Low-carb diets are an invaluable tool in dealing with health conditions such as obesity, diabetes, metabolic syndrome, lipid disorders, epilepsy, and increasingly, cancer. Martina's work, including her blog, book and apps, have been real gems for the low-carb community. Her real-food approach and attention to detail sets her work apart from many others.

Prof. Eugene J. Fine, M.D.

Professor of radiology (nuclear medicine) at the Albert Einstein College of Medicine, ketogenic diet and cancer researcher.

Ketogenic diets have shown great potential in weight loss, overall health and cancer treatment. Martina's valuable contributions to the low-carb community and her involvement in the cancer research project run by our team extend beyond simply helping people follow a healthy low-carb diet. Just like Martina's blog and app, her new cookbook is an amazing resource for anyone interested in healthy living with easy to follow recipes and beautiful photography.

Alex Pearlman Ph.D.

Cancer biologist at the Albert Einstein College of Medicine, ketogenic diet and cancer researcher.

This book is a wonderful combination of the healthy tastes of the Mediterranean and the metabolic benefits of low carb. Plus, top it all off with a description of the science and you get the perfect combination!

Bret Scher, MD.

Cardiologist, lipidoplogist, and medical director at DietDoctor.

I can unequivocally recommend the New Mediterranean Keto approach to dietary wellness based on years of direct personal and professional experience with him and his scientifically validated approach.

Dr. Landon Pryor, MD

With The KetoDiet Cookbook Martina has really outdone herself. This book is filled with an amazing array of tasty recipes. I especially love the full macronutrient breakdown with each recipe (fat/protein/carbs). This is an invaluable resource for anyone living a low carb high fat lifestyle.

Maria Emmerich

Martina's popular KetoDiet blog has been a wonderful resource for those following a healthy paleo/primal low carb diet. Not only does she provide a wealth of information for successfully implementing a ketogenic diet, but also shares many of her own delicious low carb recipes. Her recipes have become staples for those seeking low carb alternatives for their favorite foods. This cookbook with 150 new keto diet recipes is a must for any low carb cook's collection.

Lisa MarcAurele

Creator of Lowcarbyum.com.

As a fellow blogger, I have known Martina for a couple of years. I have been thrilled to see her remarkable development to one of the leading bloggers in this niche. I am delighted to see that her new cookbook is really impressing! With its amazing quality, the book simply stands out from the grey crowd of the numerous low-carb and ketogenic cookbooks. That’s why I am happy to recommend the book to anybody who seeks the latest information about healthy nutrition and the best, carefully developed ketogenic recipes.

What is Keto?

The ketogenic diet is a high-fat, moderate protein, low-carb diet that causes ketones to be produced by the liver, shifting the body's metabolism away from glucose and towards fat utilisation.

According to over sixty randomized controlled trials carbohydrate restriction is the most effective weight loss tool due to its appetite suppressing effects. The benefits of healthy low carb eating extend beyond weight loss and the ketogenic diet has been used as adjuvant treatment for several health conditions.

Our mission is to help people adopt a healthy lifestyle, not just lose weight. Food quality matters and eating nutritious food low in carbs is the best way to achieve your long-term goals.
