The difference is that Health Code is not just another guide; it is a book written by a professional that provides you with the knowledge required to properly navigate the health and fitness world, as well as the countless scams and traps found throughout both the health/supplement and fitness industries. It teaches you a true awareness of your behavior and health choices, and how to change those in order to become healthier.
The health industry largely relies on uninformed individuals, as they are the easiest to sell supplements, workout guides and diets to. These are all just quick fixes. A true long-term healthy lifestyle starts with building a solid foundation: by understanding and changing your behavior. Again, this book is not just a guide; it is a practical tool that will help you gain the fundamental understanding required to take proper control over your health.
There is nothing wrong with getting a workout plan from your favorite influencer. What is absolutely crucial to understand, however, is that every body is unique and everyone's optimal diet, workout and lifestyle are unique to them. The purpose of Health Code is to equip you with the knowledge necessary to adapt these workout and diet plans to YOU and YOUR body. These plans all worked for the individual that wrote them, but that, by no means, means that they will work for you. It is essential to take these plans and adapt them to your specific body and its needs.
