Just read about Mariann’s incredible change in health. The laundry list of benefits she has experienced is inspiring! – Dr. Perlmutter

In January 2015 I was diagnosed with Polymyalgia Rheumatica, and was prescribed by the rheumatologists to take Prednisolon on a daily basis. I did that for more than one year, gradually withdrawing the amount of Prednisolon. By the end of the treatment (May 2016) my muscle pain came right back. A friend of mine recommended to read your book, Brain Maker, and I am deeply thankful that I did. It gave me the tools to take full responsibility for my health and today, after four months of getting out of stress and following an anti-inflammatory diet, I feel better than in many years and my Polymyalgia is almost gone.

I am still working to get 100% well, but I can walk without pain now, I can dance, and I am thinking of starting jogging/running again. Further, I lost 20 pounds and have reached my ideal weight from my youth. I feel stronger, lighter, more flexible – and also years of fatigue are gone. My mood is lighter and I am proud of having taken back the responsibility of my body.

Before I read Grain Brain and Wheat Belly, I LOVED bread. I consider myself a baker and did not want to stop eating wheat or grain, but I eventually did. Over the 3 month period in which I stopped eating wheat, I lost 35 pounds with little or no increase in exercise. I’m 65 and I felt so much more energized that I began a walking program after the weight loss. The weight stayed off, but the bloating, constipation and indigestion returns if I indulge in pizza, cookies, or sandwiches. It’s immediate and painful and takes about 2 days to repair the damage. I don’t know if it’s grain, pesticides, or both but I need to stay away from these foods!

Over a period of twenty years, and seventeen doctors, I sought in vain to find help for chronic diarrhea and severe joint pain. Along the way I could only find partial relief through medications that caused numerous side effects. No MD ever tested me for allergies. Then my feet went completely numb. When I asked the neurologist why (since I did not have diabetes), he told me at least 40% of people never discovered why they have peripheral neuropathy.

Then came the MIRACLE of Grain Brain and Wheat Belly. After only two weeks of being grain-free, I had feeling back in my feet, no more joint pain, and my diarrhea was much improved. Invigorated, I searched until I found a marvelous integrative medical doctor who used the Cyrex Lab tests, for food allergies, that Dr. Perlmutter had written about. Testing proved that I am severely allergic to all dairy and grapes! Now, at the age of 83, with no joint pain or diarrhea, and feet that want to dance, I have been reborn!

Three years ago I participated in a webinar that Dr. Perlmutter hosted . My daughter Hailey was then 12 years old and dying from a Leukodystrophy called Alexander disease. I was absolutely desperate to save her. She was down to 57 pounds, vomiting daily, and suffering from horrific constipation, headaches, eczema and acid reflux . After this eye-opening event, I made an appointment with a new GI doctor, and long story short it was the gluten killing my daughter.

She is now 15 years old, still, of course, has Alexander disease (it’s genetic), but is off all medications and is 83 pounds at 4’10” tall. Thank you for saving us all!

At 65 I was in top shape: 225 pounds with a six-pack, regularly boxing, weightlifting, and doing cardio. I felt, and looked, like an MMA fighter.

Suddenly I found myself sidelined by serious leg pain, I mean the kind you cannot walk through. I quit. I had to. I couldn’t even lift a light barbell over my head from the pain! I also had malaise, brain fog, irritability, and high blood pressure. I felt 90 years old.

I got depressed because I could not exercise, not even walk. It just hurt too much. I used NSAIDs on and off, as the stiffness and pain waxed and waned. Sometimes I could not even turn over in bed. My sleep suffered.

Chris is actually a former patient of mine who recently reached out. In our exchange, he shared the story of his journey to optimal health, and I think it’s one you’ll want to read. – Dr. Perlmutter

When I was a teenager, I suffered from [sometimes] severe Tourette’s, ADHD, and OCD during my teen years and was living in almost misery. My parents were having a difficult time with the situation too. During that time, my parents and I went to numerous neurologists to try and find ways to deal with my Tourette’s. I was given pills and pills, and eventually, my parents started realizing the pills were not doing so well for me. My parents then decided to take me to you, which was the day that changed my life. One day, we made the drive from where we live in our home down to Naples, FL. You were able to give us some insight that no other neurologist or any other kind of physician was able to. You let us know that sometimes food allergies can trigger tics and you had me take multiple allergy tests. Once we got the results, we found out the particular foods that I should avoid to help lessen my tics.

This morning, after finishing my run and reading Dr. Perlmutter’s latest email, I am feeling such a profound urge to share my gratitude and a little about my own health journey.

A year-and-a-half ago I stumbled across Brain Maker on Amazon and ordered it. I was 44 years old struggling with depression, anxiety and a lifelong eating disorder. I was at a very low point. I weighed about 300 lbs. and was feeling quite hopeless. When I received Dr. Perlmutter’s book and began reading it (voraciously I might add) new hope began dawning in me. It brings tears to my eyes just remembering this because it was such a huge turning point for me. I took what I learned from Brain Maker (and other sources too) and began turning my health and my life around.

Today I am a 45 year old woman (a very fit and muscular one too!) at 140 pounds. I still struggle somewhat with depression and food issues, but I also have more knowledge and hope too. It is certainly not always easy, but I am so grateful today for Dr. Perlmutter and so many others like him who spread a message of hope and give so many people the knowledge to be in control of their own health and happiness.

About 5 years ago I moved to Australia from England. I was about average weight, but you could probably say I was “skinny-fat” at the time (not much muscle). After a year of living in a new country and eating a lot of carbohydrates, junk food and sugars my weight ballooned to 185 lbs. (I’m 5′ 7″). I tried to lose the weight through cardiovascular exercise and low-fat diets, but this just made things worse, I was always hungry and just gained more weight. When I couldn’t stomach the diet anymore, I returned to my usual eating habits, and with it came excess weight gain.

In 2013 I was looking through the Internet for another solution and stumbled across ketogenic diets. I read lots of studies and participated in the forums online, and finally adopted this lifestyle. Continue reading

In just three months of living a Paleo life, I’ve lost 15 lbs., I have more energy, and my thyroid function has improved mightily! My doctor is very impressed with my success.

In July 2015 I found “Grain Brain” in a bookshop. It turned out to be much-needed validation of my gluten-free diet, which lead to better thyroid function and reduced severity of allergies for me, and healed digestive issues for my husband. But Grain Brain was also eye-opening for some of the new ideas it introduced, like the fact that a full English breakfast (without bread, of course!) is actually quite healthy! This was most important for my husband, a Brit.
