The Claim

A 6-week Modified Atkins Diet was associated with a reduction in monthly psychogenic non-epileptic seizure frequency in a cohort of 17 adult patients, with a Hedges' effect size of 0.618, despite the absence of a statistically significant difference between the diet group and control group.

In plain English

In a group of 17 adults with psychogenic non-epileptic seizures, following a Modified Atkins Diet for six weeks was linked to fewer seizures each month, though the reduction was not statistically different from what was seen in a control group.

See the scientific wording

A 6-week Modified Atkins Diet significantly reduced monthly psychogenic non-epileptic seizure frequency in a small group of adult patients (n=17), with a Hedges' effect size of 0.618, despite no statistically significant difference between the diet group and control group, suggesting a potential benefit that may be influenced by non-dietary factors such as increased clinical attention or placebo effects.

Why this might work

When the body burns fat instead of sugar, it produces a molecule called beta-hydroxybutyrate. This molecule stops certain immune cells in the brain from triggering inflammation. Less inflammation in key brain areas involved in stress and emotion reduces abnormal brain activity that leads to seizures not caused by epilepsy.

    People on a low-carb diet and people on a normal healthy diet both had fewer seizures after six weeks, so we can't say for sure the low-carb diet was the reason—maybe just getting more attention helped. But it still suggests the diet might be helpful.
