What was done
This historical review examined how Wilder formulated the hypothesis for the ketogenic diet as an epilepsy treatment in 1921 and described the subsequent adoption and publication of open studies using the diet during the 1920s.
What was found
In 1921, Wilder hypothesized that the beneficial effects of fasting on seizures were mediated by ketonemia, proposed that a high-fat, very-low-carbohydrate diet could achieve similar results by inducing ketogenesis, and reported initial observations in 3 patients. Following his publications, 9 papers reporting on more than 400 patients with epilepsy were published during the 1920s. The abstract provides no quantitative outcome figures, response rates, or statistical results.
Why it matters
It outlines the origin of ketogenic dietary therapies for epilepsy, documenting how fasting observations led to the initial clinical application of ketogenic protocols in the 1920s.
Limits
This is a narrative historical overview rather than a systematic review. The underlying literature from the 1920s consists of uncontrolled open series. No quantitative clinical efficacy, safety, or retention figures are reported in the abstract.
