For the last few years, the ketogenic diet, or “keto,” has been making headway in the media and fitness forums globally. With the emergence of new and often conflicting information and opinions, it can be difficult to start a process that you trust will work.

I have researched and implemented ketogenic principles for several years, and have the results which prove success. After being asked by dozens of individuals for advice on the ketogenic way of eating, I have written a simple, easy to understand, four-page guide (no fluff and to the point, saving you time so you can start keto quickly; if you are looking for science and extreme details, you will not find it in this guide).

The Simple Keto Guide makes implementing a ketogenic way of eating extremely easy for anyone. In this guide I have broken down keto into three separate phases which I walk you through so you can lose fat for the long-term.

My Story:

As a division one football player, I needed to be as big and strong as I could possibly be. However, after my football career ended, I knew that it would be unhealthy to continue on weighing 293 pounds. I had read about keto on bodybuilding forums in college, and had been intrigued. Once I finished playing football, I decided that I would start eating a ketogenic diet and try to obtain a lean, aesthetic physique. 

After doing my due diligence and putting together a plan, I implemented it and trusted it. The weight began to fall off. Inspired by the initial weight loss, I began researching more and more and continued to refine my way of eating. 

After one year of eating this way, I lost 92 pounds and looked the best that I ever had in my entire life. What was amazing was that I never felt that I was on a diet as I enjoyed all of the foods I was eating. People were amazed when I answered their questions as to what foods I ate.

After assisting several former teammates, friends, and colleagues in their weight loss goals, I have summarized this successful and proven method into a simple guide in order to help you too.

This guide is a brilliantly crafted roadmap to sustainable fat loss, presenting a refreshing departure from the restrictive and often unsustainable “diets” flooding the market. The author’s approach, aptly termed a “way of eating,” is grounded in a low-carb, whole-foods philosophy that prioritizes long-term health and practicality over quick fixes or gimmicky supplements. The text shines with its clear, structured breakdown into three distinct phases, making it accessible for beginners while offering enough depth to satisfy those familiar with nutritional science.Phase One is a masterclass in setting realistic expectations, easing readers into the low-carb lifestyle with a focus on adaptation rather than perfection. The explanation of net carbohydrates is concise yet thorough, demystifying food labels and empowering readers to make informed choices. Recommending tools like Cronometer and MyFitnessPal adds a practical layer, ensuring users have the resources to succeed. The acknowledgment of initial hunger and water weight loss is both honest and encouraging, setting a supportive tone that builds trust.Phase Two elevates the guide by introducing calorie tracking and macronutrient goals with precision. The inclusion of a TDEE calculator and conservative activity level recommendation reflects a thoughtful, science-backed approach that avoids overpromising results. The emphasis on protein as a satiating nutrient and the reassurance about weight fluctuations demonstrate a deep understanding of the psychological and physiological hurdles of fat loss, making the guide feel like a compassionate coach rather than a rigid rulebook.Phase Three is where the guide truly excels, celebrating the reader’s progress while introducing flexibility with controlled cheat days. This balance of discipline and freedom is a game-changer, fostering a sustainable mindset that can withstand real-world challenges. The cautionary note about “keto” frankenfoods is a standout, showcasing the author’s awareness of potential pitfalls and commitment to long-term success. The staple foods list is a practical gem, offering simple, versatile options that make adherence feel achievable.Overall, this guide is a stellar blend of science, practicality, and empathy. Its clear, jargon-free language and structured progression make it an invaluable resource for anyone seeking a healthier, more sustainable approach to fat loss. This isn’t just a guide—it’s a transformative blueprint for lasting change, delivered with authenticity and expertise. Highly recommended!

Response from Zack Strength

Thank you for your feedback. My goal with the guide, as stated in the description, was to provide a no-fluff four-page guide making it fast and easy to start, as opposed to containing an overload of unnecessary information that other keto content contains, often resulting in people never starting.

I hope you enjoyed the free pages I sent from The Zack Strength Meal Book that you requested.
