Abstract

This book is about achieving health and longevity by eating less and extending the "fasting period." [Three meals a day is too much] Many people eat three meals a day. However, that's too much. When you're full, you feel sleepy. This is because blood flow concentrates in the stomach and intestines, making it difficult for blood to reach other parts of the body, including the brain. Therefore, many people not only feel sleepy, but also experience fatigue and lethargy. Furthermore, overeating weakens the immune system, worsens the gut environment, and impairs the function of white blood cells, among other problems. As a result, it can lead to various diseases, including diabetes, dementia, and cancer. [Various effects of fasting] On the other hand, extending the "fasting period" allows the internal organs to rest longer, revitalizing them. As a result, body heat increases, excretion is promoted, immunity is boosted, and longevity genes are activated, leading to various effects such as prevention of myocardial infarction, stroke, dementia, and cancer. Of course, since you'll be eating less, you can also successfully lose weight! In this book, a doctor who has been warning against overeating for over 50 years shares an "ultra-low-calorie health method" that is easy to implement and can extend your healthy lifespan.
