To go from 15 medications every day to just one? Wonderful to hear how Judy has been freed from this burden. – Dr. Perlmutter

I developed epilepsy in 1966 after falling off a bike. This preceded 50 years of never-ending seizures, which were unresponsive to a plethora of medical treatments. But, since switching to this diet, I have been seizure-free! I’ve also gone from taking 15 medications/day to just 1 every night. The result? I feel better than I did at 30, 20, or even 15 years-old!

Agi R. from Hawaii

I spent 10 years trying Chinese herbal treatments, Ayurvedic medications, and detoxes to treat my ulcerative colitis. In that 10 years I experienced occasional remissions, and I always had the sinking feeling that these colon problems would come back. Now, after following a ketogenic diet, taking supplements, exercising, and fasting, I am healthy and full of energy! Here’s to my health!

Ken L.

The most amazing thing about Ken’s story is that he managed this without any expensive pills or medication. It was all diet and lifestyle changes! – Dr. Perlmutter

At age 62, I was diagnosed with severe type 2 diabetes. I was told I would always be a diabetic and would need to be on medication for the rest of my life. At the time, my fasting blood glucose was 220 and I weighed 185 lbs. (I am 5’11”).

After researching lifestyle options, I embarked on a high healthy fat/low-carb diet with supplementation of Vitamins D and K2, and gut improvements with probiotics and homemade fermented vegetables. Today, at 64, my fasting blood sugar is 72 and I weigh 159 lbs. That’s nearly 30 lbs. lost! I am probably in the best shape I’ve managed in the past 30 years. This was achieved with absolutely no medication whatsoever, and I couldn’t be happier.

Juan P.

Leading up to my decision to take back control of my health, I was diagnosed with myriad health problems that, if I didn’t make a change, could have debilitated me for the rest of my life. Collectively, I was diagnosed with metabolic syndrome (hyperinsulinemia), benign fasciculation syndrome (BFS), celiac disease, atherosclerosis, focal seizures of the temporal lobe (affecting memory), and severe twitching.

Fast forward to several months, and now years, later, and after embracing a Paleo diet and making the lifestyle changes I needed to, I’ve now lost 180lbs, and seen my life turn almost entirely upside down, but for the better. I can’t wait to see what the future holds.

Lucy K.

Our small family is following the gut healing protocol we’ve recently discovered in books like Brain Maker, and to our delight our 25 year-old daughter, who is high-functioning special needs and has severe brain injuries and, is reaping numerous benefits. Her brain seems to be perking up, she has more energy ,and is sleeping less and getting active. Ever since she went through puberty she has been very quiet and introverted, but no we begin to notice her speaking more. All this after only a month or more on the healing protocol!

Christopher E.

I really enjoyed Christopher’s story, and it’s one I think you’ll want to share with friends or family members who are hesitant to try out this lifestyle. – Dr. Perlmutter

Thought I’d throw this out there because I’ve managed to drastically improve my health with a few changes.

I didn’t start out unhealthy,  but I had let myself get run down through a combination of work stress, physical stress, and poor nutrition. I’m not an old guy and I’ve always been able to get away with whatever I wanted to do, so why not work eighty hours a week, train to climb a mountain, and knock out the Bataan Death March all in a six month period, all while getting four hours of sleep a night and supplementing with lots of coffee!  Shockingly, I started feeling super-fatigued every day a few weeks after the mountain climb, and then, to my surprise, my hair started falling out. Seriously, patches of hair started falling out!  Being an Army Officer, I keep my hair short, but one day one of my sergeants said, “Sir, what’s going on with the back of your head?”  I checked it out and sure enough, I had a bald patch on the back of my head.

This is a rather short version of a long story.

In 1987 I weighed about 205 lbs. I was eating all kinds of trashy foods, from doughnuts to fried fish to French fries. While I exercised regularly, I also suffered from severe eating disorders. What I ingested was a lot of sugar, and I ate very poorly One morning I woke up, and a lightning bolt smacked me in the head. I needed a change.

Antonio L.

I was given Grain Brain and Brain Maker as birthday presents on Jan. 22, when I reached age 71, and started a gluten-free, sugar-free, high-fat diet on Feb. 1

After 25 days, I have solved two of the 3 “neurological” health problems I had: left arm trembling while leaning the arm on the arm of a chair, loss of equilibrium, and memory deterioration. The first two are now gone, but for the memory recovery I cannot yet claim an improvement, but I am hopeful. Further, I would like to think that maybe I have improved my speech as well, since before the diet I was reaching the point where it was difficult to have a fluent conversation, because my brain and mouth simply could not speak to each other. I have also lost 3kg of weight!

Stories of children getting their health, and their future back, like this, are truly uplifting. – Dr. Perlmutter

My 11 year old son suffered tremendously. It’s no stretch to say there are days he just doesn’t want to wake up. He was diagnosed with depression, anxiety, OCD, daily nausea, severe eczema, joint pain, psychotic episodes, and unexplained weight gain. Beyond that, he was obese: 65 pounds heavier than his brother, who is only 13 months younger than him. Diets didn’t work, antidepressants did nothing, and neither did the countless therapists he saw. Nothing helped, but I kept searching.

The best day of our families lives came 2 years ago when a new doctor told us to eliminate sugar, gluten, dairy, processed foods and legumes from his diet, and to go organic. By day 2 all his symptoms were gone and I mean gone!!!!!! It was unreal. I am constantly telling people and doctors about my son’s success! I am so so so thankful for your new book, and that there is a real movement and plan that can change people’s lives.

Lizzie C.

The story of Lizzie and her family, though long, is a must-read. – Dr. Perlmutter

I have lived the past decade of my life in terrible fear of developing early on-set Alzheimer’s disease. I am 26 this year, and I am the 4th child in a family of five girls. When I was 12, my mom started to get what I now know as the classic signs of Alzheimer’s. She was only in her 40s. Unfortunately, she ate the low-fat, whole-grain diet that was and, still is, so popular. Within a year of noticing symptoms, my mom had to go live in an assisted living home. No doctors knew what was wrong with her and many said she had Huntington’s Disease, although she tested negative for it. Three years after her first symptoms, she passed away. About five years later her sister also passed away from the same thing. My grandmother also had the same symptoms and died very young. They all had very stressful marriages.

My sisters and I have always been terrified of getting sick like our mother. In recent years we learned that her illness was early on-set Alzheimers. It was helpful to know the cause, but inside we all felt full of despair, as if a death sentence had been placed on us. It has affected all of our life choices, even the choice to have children and pass on this gene. Continue reading
