Migraines and Blood Sugar: Should I eat carbs every couple of hours to prevent low blood sugar from causing a migraine?
According to naturopathic physician Dr. Beverly Yates, ND, understanding how your brain fuels itself may be one of the most powerful ways to prevent migraine attacks.
This article will break down the connection between blood sugar, brain energy, and migraines, along with practical steps you can start implementing today to reduce migraine frequency and intensity.
The Brain Energy Crisis Behind Migraines
Your brain is an energy-hungry organ.
Dr. Amelia Scott Barrett, MD explains the connection clearly:
“The brain is an incredibly energy hungry organ. Some people say it’s only 2% of our body weight and yet it uses up 20% of our energy… If those neurons cannot generate enough energy, the cells can’t work right.”
When neurons struggle to produce enough energy, they begin releasing abnormal chemicals that activate pain pathways in the brain.
That cascade can trigger a migraine.
In other words:
Migraines are often a symptom of brain energy instability.
And one of the biggest drivers of that instability is blood sugar fluctuations.
The Blood Sugar Roller Coaster That Triggers Migraines
Many migraine patients notice a pattern: If they skip a meal or their blood sugar drops, a migraine begins.
Doctors often respond with advice like:
“Just eat carbohydrates every few hours.”
Unfortunately, according to Dr. Beverly Yates, this advice often makes the problem worse.
“If they eat just carbs and they’re not eating other food groups with it… they are much more likely to have a big blood sugar response… insulin has to chase it and try to catch it.”
This leads to what she calls the blood sugar roller coaster.
Here’s how that process works:
1. You eat a high-carbohydrate food.
2. Blood sugar spikes rapidly
3. Insulin surges to bring glucose down
4. Blood sugar crashes, and that can be a migraine trigger.
As Dr. Yates explains:
“Once insulin gets a hold of all that blood sugar… they dip too low. Now they’re back in trouble again in the land of hypoglycemia.”
For people prone to migraines, these fluctuations can be a major trigger.
The Migraine Nutrition Strategy That Stabilizes Brain Energy
Rather than constantly snacking on carbohydrates, Dr. Beverly Yates recommends a structured blood sugar-stabilizing nutrition framework.
Instead of the traditional three food groups, she emphasizes four essential food groups for metabolic stability.
“I talk about four food groups… protein, fiber, healthy fats, and complex slow-burning carbohydrates.”
This approach helps maintain steady energy supply to the brain, reducing migraine triggers.
Let’s break down each of these migraine-friendly food groups.
1. Protein: The Foundation for Stable Blood Sugar
Protein slows digestion and helps prevent rapid glucose spikes.
Examples of migraine-friendly protein sources include:
• Eggs
• Grass-fed meat
• Wild fish
• Pasture-raised poultry
• Greek yogurt
• Cottage cheese
• Collagen or protein powders
Starting meals with protein helps stabilize blood sugar early in the meal.
2. Fiber: The Overlooked Migraine Nutrient
Dr. Yates emphasizes fiber so strongly that she considers it its own food group.
“I make fiber its own food group because it’s so critical for blood sugar stability.”
Fiber slows glucose absorption and helps maintain steady brain fuel.
Top high-fiber foods include:
• Leafy greens
• Chia seeds
• Flax seeds
• Avocados
• Beans and lentils
• Broccoli
• Brussels sprouts
Low fiber intake is extremely common in modern diets and may contribute to metabolic instability that triggers migraines.
3. Healthy Fats: Long-Lasting Brain Fuel
Healthy fats provide a steady, slow-burning energy source for the brain.
Examples include:
• Olive oil
• Avocado oil
• Coconut oil
• Nuts
• Seeds
• Fatty fish
• Grass-fed butter or ghee
Fat also helps slow digestion, preventing glucose spikes.
4. Slow-Burning Carbohydrates
Not all carbohydrates are equal.
The goal is to choose complex carbohydrates that digest slowly rather than rapidly spiking blood sugar.
Examples include:
• Beans
• Lentils
• Chickpeas
• Quinoa
• Sweet potatoes
• Resistant starch foods
Dr. Yates recommends eating carbohydrates last during a meal after protein, fiber, and fats.
This dramatically reduces blood sugar spikes.
The Surprising Foods That Spike Blood Sugar
Many migraine patients are shocked to discover that foods marketed as “healthy” may actually destabilize their blood sugar.
Dr. Yates highlights several surprising examples.
1. Whole Wheat Bread
Many people assume whole wheat bread is blood sugar-friendly.
But for many individuals it behaves similarly to refined carbohydrates.
“Whole wheat bread… for many people does not have enough fiber and is essentially a simple carbohydrate.”
2. Certain Fruits
While berries tend to be well tolerated, some fruits may spike glucose.
Examples include:
• Pineapple
• Certain varieties of fruit depending on the individual
The key is individual testing.
3. Starchy Vegetables
Even nutrient-dense foods like squash may trigger glucose spikes in some people.
Dr. Yates recommends keeping the skin on vegetables when possible to increase fiber content.
Why Breakfast May Be the Most Important Meal for Migraine Prevention
Many people begin their day with carbohydrate-heavy breakfasts like:
• Oatmeal
• Toast
• Cereal
• Smoothies
But these foods can lead to mid-morning blood sugar crashes.
Dr. Amelia Scott Barrett shared an example from her own experience:
“I would always notice every day around ten or ten-thirty… I would get hangry. I ate a big breakfast, I was super full, and yet I was starving a couple hours later.”
The problem?
A high-carbohydrate breakfast.
Instead, migraine sufferers often benefit from high protein, high fiber breakfasts such as:
• Eggs with avocado and vegetables
• Greek yogurt with chia seeds
• Protein smoothie with fiber and fat
• Leftover dinner protein with vegetables
Timing Carbohydrates for Migraine Prevention
Another important factor is when you eat carbohydrates.
Morning cortisol levels can increase glucose sensitivity.
That means the body may tolerate carbohydrates better later in the day.
Dr. Yates observes:
“A lot of people… if they want to have more carbohydrates… it needs to be the middle of the day.”
For migraine sufferers, this timing shift can make a significant difference.
Actionable Steps to Reduce Migraines Naturally
Here are practical strategies you can begin implementing immediately.
1. Start Meals with Protein and Fiber
2. Avoid Carbohydrate-Only Meals
3. Upgrade Your Breakfast
4. Increase Fiber Intake
Aim for 25–35 grams per day.
Most people consume less than half of that amount.
Final Thoughts: Stabilizing Brain Energy to Prevent Migraines
Migraines are complex neurological events, but one underlying factor is often overlooked:
brain energy instability.
When blood sugar fluctuates wildly, the brain struggles to maintain the steady energy supply it needs.
By stabilizing blood sugar through balanced meals, proper nutrient timing, and individualized food choices, many migraine sufferers can significantly reduce attack frequency and severity.
The key principles are simple:
• Prioritize protein and fiber
• Include healthy fats
• Eat carbohydrates strategically
• Avoid blood sugar spikes
• Personalize your diet
For many patients, these foundational changes can be transformative.
Your brain thrives on stable fuel, and when you provide it, migraines may become far less frequent.
