The ketogenic (keto) diet has surged in popularity in recent years, with millions of people adopting its low-carb, high-fat approach for weight loss, improved energy, and overall health benefits.
However, the keto diet is far from a new fad—it has deep historical roots, beginning as a medical therapy nearly a century ago before evolving into the mainstream diet it is today.
In this article, we’ll explore the fascinating history of the keto diet, from its origins in medical research to its explosion as a global health trend.
The Origins: Early Uses of Fasting for Healing
The principles behind the keto diet date back thousands of years, even before the word “ketogenic” was coined. The concept of using fasting to treat medical conditions has been around for centuries.
Ancient Times: The Use of Fasting for Epilepsy
Historical texts, including those from Ancient Greece, suggest that fasting was used as a treatment for epilepsy. Hippocrates, the father of modern medicine, recorded that fasting could help manage seizures. Similarly, biblical references mention fasting as a means of spiritual and physical purification, which inadvertently promoted metabolic changes similar to ketosis.
1920s: The Birth of the Ketogenic Diet in Medical Science
By the early 20th century, doctors and researchers sought to replicate the benefits of fasting without requiring patients to abstain from food completely. In 1921, Dr. Russell Wilder at the Mayo Clinic developed what he called the “ketogenic diet”—a high-fat, low-carbohydrate diet designed to mimic the effects of fasting while providing adequate nutrition. The diet effectively reduced seizures in epilepsy patients, particularly children, making it a standard treatment in the medical field.
The Decline and Resurgence of Keto in Medicine
1950s–1970s: The Rise of Anti-Fat Dietary Guidelines
Despite its effectiveness, the ketogenic diet fell out of favor in the mid-20th century as new anti-fat dietary guidelines emerged. During the 1950s, research linking saturated fat to heart disease led to widespread recommendations for low-fat diets, causing high-fat approaches like keto to become less popular.
At the same time, new anti-seizure medications were developed, reducing the reliance on dietary treatments like keto for epilepsy.
1990s: Keto Returns to the Medical Field
The ketogenic diet remained relatively obscure until the 1990s when Hollywood producer Jim Abrahams revived interest in its medical potential. His son, Charlie, suffered from severe epilepsy that did not respond to medication. After trying the keto diet, Charlie’s seizures disappeared, leading Abrahams to establish The Charlie Foundation to promote keto as a treatment for epilepsy. This sparked renewed scientific research into the diet’s effectiveness for various neurological disorders.
Keto Goes Mainstream: The Rise of Low-Carb Diet Trends
Early 2000s: The Atkins Diet and Low-Carb Movement
While the keto diet was primarily used for medical reasons, the low-carb approach began gaining traction for weight loss in the early 2000s. Dr. Robert Atkins popularized the Atkins Diet, a low-carb plan that encouraged fat consumption while restricting carbs—similar to keto but with a more flexible approach. This laid the foundation for the growing acceptance of high-fat, low-carb eating.
2010s: The Modern Keto Boom
By the 2010s, the ketogenic diet had fully entered the mainstream. A combination of factors contributed to its popularity:
- Scientific Research – Studies on keto’s benefits for weight loss, diabetes, and neurological disorders gained traction.
- Celebrity Endorsements – Influential figures like Halle Berry, Tim Tebow, and LeBron James publicly praised the diet’s effects.
- The Paleo and Low-Carb Movement – The popularity of the Paleo diet and low-carb eating created a foundation for keto’s rise.
- Social Media & Online Communities – Websites, blogs, and social media platforms spread keto success stories, meal plans, and research, making it more accessible than ever.
Keto Today: More Than Just a Diet
Today, the ketogenic diet is not just a diet but a full-blown lifestyle movement. From athletes to everyday individuals, people use keto for a variety of reasons, including:
- Weight Loss: The body’s ability to burn fat for fuel makes keto a powerful weight-loss tool.
- Cognitive Benefits: Many people report improved mental clarity and focus while on keto.
- Diabetes Management: Research shows keto can help regulate blood sugar and insulin levels.
- Endurance and Performance: Some athletes use keto to enhance endurance and fat adaptation.
- Neurological Health: Beyond epilepsy, keto is being studied for potential benefits in Alzheimer’s, Parkinson’s, and other brain conditions.
The Future of the Keto Diet
As more research emerges, the keto diet continues to evolve. Scientists are exploring keto’s role in cancer treatment, metabolic health, and longevity. Additionally, new variations like cyclical keto (alternating between keto and higher-carb days) and targeted keto (adding carbs around workouts) make the diet more adaptable.
Final Thoughts
The ketogenic diet has come a long way—from an ancient remedy for epilepsy to a global health trend embraced by millions. While it started as a medical therapy, its modern applications extend far beyond epilepsy, offering benefits for weight loss, energy, and overall well-being.
Whether you’re interested in keto for health reasons or just curious about its history, one thing is clear: the ketogenic diet is here to stay. As research continues, we may discover even more ways this powerful dietary approach can improve our lives.
