Ketones or Low Carbohydrate? The GAPS Seizure Theory

The original ketogenic-diet theory treated ketone bodies as the active mechanism in seizure control. Dr. Campbell-McBride questions that explanation because blood ketone levels do not reliably correlate with seizure control and proposes low carbohydrate intake as the shared mechanism.^[1]

How the Older Chapter Questions the Ketone Explanation

Campbell-McBride says ketone concentration does not correlate with anticonvulsant effect and argues that ketones may be an alternative fuel while another process changes seizure activity. This is the reasoning in her chapter, not a measurement showing that ketones never contribute to seizure control.^[1]

Dr. Campbell-McBride’s Alternative Explanation

Her own reading, stated as her clinical opinion in the book, is that the brain simply uses ketone bodies as an available fuel source while the body deals with the real cause of the seizures somewhere else entirely.^[1] In her view, what all of the epilepsy diets, classic ketogenic, MCT, Modified Atkins, and LGIT, actually share isn’t the ketosis itself. It’s a low carbohydrate content, and specifically the exclusion of heavily starchy, complex carbohydrates.

The Starve-the-Pathogens Mechanism

This is where her theory connects directly to GAPS’s own approach. GAPS removes all starchy foods and complex carbohydrates, the same exclusion she identifies as the common thread across the epilepsy diets.^[1] Her broader position, developed throughout the GAPS book, is that carbohydrates, particularly starch and refined sugar, feed disease-causing microbes throughout the body, in the gut and elsewhere. Sharply restricting carbohydrate intake cuts back the activity of those pathogens directly. If pathogen activity and the toxins it produces are what’s actually driving a given seizure disorder, then the mechanism isn’t ketosis at all. It’s starvation of the organisms generating the problem in the first place.

What the Comparison Does and Does Not Test

The author uses results with Modified Atkins and LGIT to support her low-carbohydrate explanation. The comparison helps explain her hypothesis, but the dietary reports do not directly measure gut microbes or isolate one shared mechanism in every participant.^[1]

Her current book still says ketogenic treatment works in many epilepsy cases, though not everybody. It explains deliberate ketosis separately and says most people following GAPS do not need to pursue it. The Ketogenic GAPS guide covers that distinction.^[3]

Where GAPS Differs From the Ketogenic Diets

Standard GAPS and the classic ketogenic diet are different protocols. GAPS focuses on food selection, gut flora and digestive recovery; it is not automatically a measured ketogenic state. The 2020 book explains that No-Plant GAPS may not be ketogenic either, because metabolism, gut flora and protein intake differ between people.^[3]

Keep the Observation and Explanation Separate

A seizure count, a ketone result and an explanation for why something changed are different records. If treatment is being reviewed, keep the measured result beside the diet and medication history. Do not infer a gut-microbe result from a ketone number, or change a prescribed diet ratio because two diets share a broad label.

Frequently Asked Questions

Do Higher Ketone Levels Mean Better Seizure Control?

Not reliably, according to the GAPS book. Ketone levels don’t consistently correlate with how well seizures are controlled, which is part of why the original “ketones suppress seizures” theory has been questioned.^[1]

What Shared Mechanism Does GAPS Propose?

Dr. Campbell-McBride’s view is that the shared mechanism is low carbohydrate intake, specifically the exclusion of starchy, complex carbohydrates that feed disease-causing microbes.^[1]

Is GAPS a Ketogenic Diet?

Standard GAPS is not automatically ketogenic. The 2020 book describes deliberate Ketogenic GAPS separately and says No-Plant GAPS does not always produce ketosis.^[3]
