Ever since I discovered Grain Brain, my life has changed for the better. I’m 35 years old, and I have suffered from severe and regular migraines for as long as I can remember. Two months ago I read the book and I decided to start a gluten-free diet that was low in carbohydrates, and just four days later I began to feel great! I had more energy and no headaches, it was so incredible. I have lost weight too!

The success Cindy has seen with her migraines has been well-documented in others. There are some studies available on my site that highlight this. – Dr. Perlmutter

I have suffered from migraines for 26 years. They have been debilitating and over the years I have tried everything to prevent them. My neurologist has prescribed an arsenal of drugs, including beta-blockers, anti-depressants, calcium channel blockers, antihistamines and topamax. I tried eliminating triggers from my diet to no avail. I always got a migraine when the pressure dropped and there was a storm. Nothing stopped my weekly headaches. Sometimes I had them several times a week.

Four years ago I found a doctor that changed my way of thinking about my diet. My mother has Alzheimer’s and I want to do whatever I can to prevent it. My blood work started showing elevated blood sugar and I couldn’t figure out why.

She coached me to eliminate gluten and to increase the right kind of protein in my diet. I was eating too many carbs.

The migraines continued.

What I like about Sandy’s store is the role her husband’s aunt played. On both social media and this website, I always talk about the important of sharing this information with others. The reason why is because I want to facilitate more stories like Sandy’s. – Dr. Perlmutter

I am listening right now to your talk on The Gluten Summit; at around minute 35 you talk about the 66 year-old man who eliminated the migraines he had suffered from his entire adult life. I just turned 60 this month. I want to tell you I’ve had a similar success over the past 18 months after deciding to quit carbs.

I recall having headaches as early as 6th grade: I got in the car after school and my head was hurting, and I can still hear my mother saying “You shouldn’t be having these headaches this young.” My dad really suffered from headaches, and I believe now that he had migraines. We just assumed that I inherited the tendency to have headaches from him; my mother and brother didn’t have them.

I was probably early 20s when I realized that my headaches fit the description of migraines. The left side of my head would just feel like it was exploding, I couldn’t see out of my left eye, sick to my stomach…light, sound, movement, made it worse, etc. Me being me, I would always try to tough it out rather than go from doctor to doctor in a search of pills to take (perhaps because I thought I had inherited this problem and just had to put up with it). So, for many years, I took extra-strength Excedrin hoping it would help (usually it didn’t) with ice packs or massage. I worked as a computer programmer for 7 years after college when I finally had to quit; I just could not get through the day and suffer through the headaches. I eventually went to several doctors and tried various drugs, which only helped sometimes, but usually the headache came back in about 12 hours. Given the cost and the fact that they often didn’t work, I gave up the drugs. Not once did any doctor ask what I was eating.

Ty's before and after photoshoot

Ty T.

Ty sent me his story on Facebook, and after reading it, I knew I had to share it with you all. I’m impressed by his dedication to the LCHF lifestyle, and how he works to inspire and motivate others. – Dr. Perlmutter

In September 2013, I decided to finally transition to a low-carb/high-fat lifestyle (and also 100% free of grain and sugar) and since then I have lost 82 pounds. I have been reading and researching ketogenic diets for about 10 years, and have had much success in the past, but this time something just clicked. I no longer “treat” myself to low-carb grains, or fake sugars. I feel fabulous! My skin conditions have completely cleared up. My mental fog is gone. Intestinal distress, muscle cramps, and headaches are a thing of the past.

Peter’s ability to point to these concrete examples of how his life has improved since taking on a Grain Brain lifestyle is wonderful. I’m so glad to see the many different ways in which this change has helped him. -Dr. Perlmutter

Two weeks after starting Dr Perlmutter’s suggested regiment I count these four successes:

  1. I am actually enjoying my meals. They’re more flavorful and fun to prepare.
  2. I was initially motivated by the possibility of lessening depression: my mood has been even, without feeling either manic nor depressed.
  3. No days lost to sinus headaches nor brain fog. This was a weekly occurrence for many years.
  4. I’ve laundered my size 38 jeans and put them away, hopefully forever. This was an unsought benefit but makes for a great encouragement to continue.

I am a 68 year old man who was given over to excessive quantities of sugary breads like cinnamon buns and doughnuts, as well as moderate consumption of beer and grain alcohols. I don’t think it is an exaggeration to say Dr. Perlmutter’s book has changed my life.

Here’s a compelling story showing just how powerful a gluten free diet can be in seemingly unrelated problems like migraine headache and depression. – Dr. Perlmutter

I first visited Dr. Perlmutter approximately one year ago after having a mild stroke at age 48.  Clearly, I wanted answers on how to prevent another such brain event. After Dr. Perlmutter performed some testing, he found that I was gluten intolerant and deficient in various vitamins and minerals.

After being perfectly healthy for 34 years of my life, I was diagnosed with multiple sclerosis on September 7, 2012. Of course, this was an absolutely devastating diagnosis, which resulted in gradually moving through the stages of grieving while also managing the symptoms of a MS flare. Continue reading
