Short Summary
Main recommendation: Dr. Ben Bikman argues that insulin resistance may contribute to migraines, and that a low carbohydrate diet, including ketogenic approaches, may improve migraine frequency and severity by improving insulin sensitivity. He presents this as a plausible, not proven, link supported by one human study and older case reports.
Key Points
- A 2020-era human study compared people with frequent migraines, people with other headaches, and healthy controls, using fasting measurements and an oral glucose tolerance test (OGTT).
- Fasting insulin was about 6 micro units per mL in the other-headache and healthy groups, versus 10 in the migraine group, which Bikman calls a real difference.
- After the glucose load, the migraine group's peak insulin reached 86 micro units per mL, almost double the roughly 47 seen in the other two groups, which he cites as evidence of insulin resistance.
- Bikman proposes two speculative mechanisms: the brain not getting enough glucose, or excess insulin driving nitric oxide production that overfills brain blood vessels.
- Historical reports from 1928 and 1930 described migraines stopping or declining in patients on low carbohydrate diets, and a recent case report described migraines stopping after a wife adopted a low carb diet for weight control.
Details Worth Noting
- Concrete instructions: Adopt a low carbohydrate diet to improve insulin sensitivity, which Bikman says has the most supporting evidence for migraines. He describes this as the central intervention he advocates, and he also mentions alpha lipoic acid as a supplement thought to work through insulin sensitivity. No dosage, frequency, or duration was given in the transcript.
- The OGTT method: fasting glucose and insulin are measured, then the person drinks a sugary solution, and glucose and insulin are measured at 0, 30, 60, and 90 minutes.
- Study group control: the groups were balanced for age, sex, and weight to reduce confounding variables.
- Glucose response: peak glucose at 30 minutes was about 114 mg/dL in controls and over 140 mg/dL in both headache groups.
- Caveats: Bikman says the mechanisms are speculation, and he notes that migraine treatments generally target symptoms rather than the underlying cause. He also says he has not seen migraine-specific discussion of low-carb diets in medical organizations, though the American Diabetes Association's guidelines include low carb diets.
- Anecdote: a colleague with one to two migraines weekly reported having only one in six months after adopting a low carb diet. This is a single personal account, not controlled evidence.
Bottom Line
The video frames insulin resistance as a possible metabolic root of migraines, with diet-based insulin reduction as the suggested direction, but the evidence presented is limited and largely speculative, so it should be treated as a hypothesis to discuss with a qualified clinician.
