What Is the Hay Diet?

Developed by Dr. William Hay in the early 20th century, the Hay Diet is built on the simple idea that certain food combinations support better digestion and overall vitality. By separating proteins, carbohydrates and fruits, the body can process nutrients with efficiently, reduce bloating, and sustain steady energy throughout the day.

This book takes the original principles and translates them into a modern, easy-to-follow plan — without rigid rules or deprivation. You'll learn how to build balanced plates, listen to your body's cues, and enjoy food with renewed pleasure.

It also tracks the author's 36 years of experience on the Hay Diet.

No fads. No extremes. Just real food, intelligently combined.

About the Author

Robert Johnstone was born on a Scottish hill farm in the late 1950s. Later, he moved with his family to a farm in Stowmarket, in Suffolk, England, where he farmed alongside his father. After farming for several years, he opened a Paintball Games site in 1989, which he ran successfully until 1997. Around this time, while still running the paintball site, he first came across the Hay Diet, and it completely changed his life. Later, he went on to work for Sheikh Hamdan Al Maktoum of the Dubai royal family, managing the sheikh’s 6,000-acre estate near Thetford in south Norfolk. He worked there for 19 years and throughout that entire time, he didn’t take a single sick day. Robert has now been following the Hay Diet for 35 years and has never had a bad day on it. He firmly believes the Hay Diet is the reason he has stayed fit, healthy, and mentally sharp for so long. He has kept a stable weight of 162 lbs and stays active with brisk walks through the forest near his home. He is genuinely content, always smiling, and full of life. This is his first book, written to share what has worked for him and possibly help others looking for a simpler, healthier way to eat and live.
