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!

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.

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

I started 2015 by adopting a gluten-free, low-carb lifestyle.

I had suffered from anxiety since the age of six, and added chronic stress to that when I was in my thirties. Many other symptoms would come up later, including irritable bowel syndrome in 2005, severe joint pain/muscle ache, lack of sleep, lack of concentration, depression and finally, a breakdown in 2009. Conventional medicine scratched only the surface. I was grasping at straws last year with my trying to exclude different foods from my diet, suffering acid reflux all the while. I would fall asleep to be awakened by a dead arm and, in panic, try to get the circulation back.

This regimen has saved my life. Within five days I started to sleep. Within twelve, I broke free of depressive moods. I have no joint pain or muscle ache now, no acid reflux at all. My gut feels like it’s been repaired. I do not eat any carbs and do eat a high-fat diet with extra virgin olive oil, coconut, butter, and the like. I feel energetic and feel my brain is functioning again. I am 63 now and am looking forward to getting even better. Last week, I started eating fermented foods like kimchi, red cabbage, and cauliflower. In a week or so, I will be excited to find even more improvement in my overall health.

Maari C.

The most revealing part of Maari’s story is in the final paragraph. – Dr. Perlmutter

Several years ago I started suffering from panic attacks and anxiety, and I quickly began researching holistic alternatives to the pharmacy medications doctors wanted to put me on. After three months of these attacks, my health was repaired within a month.

Fast forward seven years, and after my second pregnancy I started breaking out in hives all over my body, on top of having an under-active thyroid (a big surprise as I had an over-active thyroid). I was forced to take Synthroid. Continue reading

It’s been fifteen months since I made a forever change to my diet and lifestyle by converting to a low-carb, gluten-free, high-fat diet. From a starting point of a soft 225 lbs., I am now down to 198 lbs. and loving it!

I started small, but eliminating all sugars, carbohydrates, and gluten for 30 days. I lost 3 lbs. per week, even with no change to my gym schedule, which was sporadic at best. My jeans that were once tight were falling off my butt and I had to wash them in hot water, and shrink them. For the first time in a long time, I was happy to look at myself in the mirror after a shower – heck at 48 years young I look better than I did when went to the gym 2 hours a day when I was 20!

I committed to my new gluten-free, low-carb lifestyle 7 months ago, and have since lost 23 lbs., mostly in the first 3 months. Most noticeable to me is the reduction in body aches. I’m running twice the miles I used to because my body does not hurt like it did before. I simply feel better!
