I am not new to keto. It helped me lose 50 pounds. I am new to fasting, though. Whether you wish to eat one meal per day, fast for an entire day, or set aside an eating period each day, this book will help guide you through it. Moore's enthusiasm for keto may feel overbearing but it is for a good reason. If your current health will let you eat keto you will find that it works. Fasting seems like the next logical step. Most of the American food industry doesn't care if its food sickens you or kills you, so long as you eat its junk to the bitter end. There are no recipes in this little book, just solid information about how to fast and how to leave a supermarket with your health intact.
