The Nerve Wire
The Unexpected Calm: How Ketosis Changed My Migraine Story
In January 2026, I entered ketosis to address inflammation. My original hope was to help my peripheral neuropathy. I didn’t expect that, along the way, I would resolve a 60-year struggle with severe migraine.
For decades, migraine had been part of my life—a recurring, often disabling condition that shaped plans and narrowed what felt possible. I began a ketogenic diet for a different reason: I wanted to address inflammation and see whether that might help my peripheral neuropathy. The change in my migraine experience was unexpected.
My story is personal, not proof that ketosis will work for everyone. Migraine is complex, and a dietary approach that helps one person may do little—or even cause problems—for another. Still, the experience led me to ask a bigger question: Could the way the body uses fuel influence migraine biology? For years I took prescription medication which worker perfectly but occasionally my doctor would ask me to try a new medication because I would get through 6 boxes of 6 tabs every month. But nothing ever worked and my doctor never even once suggested nutrition as a cause.
What ketosis is—and isn’t
Normally, the body relies primarily on glucose for energy. When carbohydrate intake is very low, the liver converts fat into molecules called ketones, which can be used as an alternative fuel by the brain and other tissues. This metabolic state is called nutritional ketosis. It turns out that the brain prefers ketones. I’m 70 years old and have never felt so sharp since starting my ketosis journey. Its like someone switch on my brain and cleared the fog: (brain fog)
Ketosis is not the same as diabetic ketoacidosis, a dangerous medical emergency involving uncontrolled ketone production, usually in the setting of insufficient insulin. Nutritional ketosis is a different state, but ketogenic diets still aren’t appropriate for everyone. People with diabetes, kidney or liver conditions, a history of disordered eating, or certain medication regimens should get medical guidance before making major dietary changes.
Why researchers are interested in ketosis and migraine
Migraine isn’t simply a bad headache. It is a neurological disorder involving networks that process pain and sensory information. Its biology is still being studied, but researchers have proposed several ways ketogenic diets might influence migraine:
Energy availability in the brain: Some studies suggest that differences in how the brain uses energy may be relevant to migraine. Ketones provide an alternative fuel source, though it remains uncertain whether this is the key reason some people improve.
Excitability and signalling: Ketosis may affect the balance of chemical signals involved in nerve activity. Researchers are investigating whether these changes could influence the brain’s tendency toward migraine-related excitability.
Inflammatory pathways: Ketogenic diets may affect some markers and pathways related to inflammation. That does not mean they reliably reduce inflammation throughout the body, or that inflammation is the sole cause of migraine.
Mitochondrial function: Mitochondria help cells produce energy. Because energy metabolism has been explored in migraine research, the possibility that ketones affect mitochondrial function has attracted attention.
These are plausible mechanisms, not settled explanations. The science is developing, and it cannot yet tell us exactly why ketosis may help some people—or predict who will benefit.
What the evidence says
Research on ketogenic diets for migraine includes small clinical studies and reports of improvement in some participants. The findings are encouraging enough to justify further study, but they are not conclusive. Studies vary in size, diet design, duration, and participant characteristics; larger, well-controlled trials are needed.
That distinction matters. A personal improvement can be meaningful without proving cause and effect. Migraine can fluctuate over time, and changes in sleep, hydration, stress, food routines, medication, or other factors may also affect symptoms. My experience is one data point—important to me, but not a substitute for clinical evidence.
The practical realities
A ketogenic diet can be demanding. It typically requires substantial carbohydrate restriction and careful attention to food choices. Some people experience headaches, fatigue, constipation, nausea, or other symptoms while adapting. This usually lasts for about 3 days and is often referred to as The Keto-Flu. Restriction can also make eating socially or practically difficult, and a poorly planned diet may lack fibre or key nutrients. Having said that, after my last visit to the doctors for a routine check-up as I’m 70 years old now should excellent improvements in all of my blood markers and a 16 kilo drop in weight.
If you’re considering a ketogenic approach for migraine, it’s wise to discuss it with a clinician—ideally one familiar with both migraine and nutrition. A registered dietitian can help assess whether it’s appropriate and how to make it nutritionally balanced. Don’t stop or change prescribed migraine medication without consulting your prescriber.
If you and your care team decide to try it, tracking can help you understand what’s happening. Record migraine days, severity, medication use, sleep, hydration, and other relevant changes. A clinician can help you set a reasonable trial period and evaluate whether the benefits outweigh the burdens.
My takeaway
I entered ketosis in January 2026 hoping to address inflammation and, perhaps, my peripheral neuropathy. Instead, the most striking change for me was an unexpected end to a 60-year issue with severe migraine. I’m grateful for that outcome—and careful about what it does and doesn’t mean.
Ketosis is not a guaranteed migraine treatment, and it shouldn’t replace individualized medical care. But the connection between metabolism and migraine is worth studying. For some people, a medically supervised dietary approach may become one part of a broader care plan.
For me, a change made for one health concern brought an astonishing surprise. The science hasn’t fully caught up with my experience, but it offers a reason to keep asking questions.
