What is ketogenic diet?
ketogenic diet
The ketogenic diet is a dietary intervention developed in 1921 by a physician for the sole purpose of treating epilepsy, according to Chris Palmer.
How it developed
- Aug 2026 - Chris Palmer said the ketogenic diet was developed in 1921 by a physician for the single purpose of treating epilepsy.
- Aug 2026 - Palmer said about one-third of patients become seizure-free, another third get a 50% or greater reduction in seizure frequency, and the final third see no benefit.
- Jul 2026 - Martin Picard said electrons stuck on ketones instead of glucose can flow more easily, which many people report as more energy on the diet.
- Aug 2026 - Palmer said patients who did not reach ketosis often got no clinical benefit, and that benefit appeared once they entered ketosis.

The ketogenic diet was designed in 1921 exclusively as an epilepsy treatment, not a weight-loss or metabolic diet, contradicting its popular identity as a modern weight-loss intervention.

In treatment-resistant epilepsy patients who failed both drugs and surgery, the ketogenic diet renders one-third seizure-free, one-third with 50%+ seizure reduction, and one-third non-responsive.
“One/3 becomes seizure-free, another third get a clinical benefit, meaning a 50% or greater reduction in their seizure frequency and the other third it doesn't seem to work.”Chris Palmer · 27 Aug 2026

Early clinical use of the ketogenic diet for epilepsy: 50% of patients became seizure-free and an additional 35% had 50% or greater seizure reduction.

Martin Picard explains why the ketogenic diet produces more felt energy: electrons on ketones flow through mitochondrial circuitry more easily than electrons on glucose, not because of extra calories.
“The ketogenic diet, which I know you've tried, many people report more energy on the ketogenic diet. It's not because you eat more calories. It's because those electrons that are stuck on ketones instead of being stuck on glucose can flow more easily.”Martin Picard · 2 Jul 2026
Chris Palmer on the ketosis threshold for psychiatric benefit.
“When they were trying the diet and not getting ketones, they often did not get a clinical benefit. It was once they got into ketosis that I began to notice the clinical benefit.”Chris Palmer · 27 Aug 2026
