Incredible story of an entire family who benefited from this set of lifestyle changes. – Dr. Perlmutter

I was diagnosed with Hypothyroidism in the fall of 2013 and my doctor prescribed Levothyroxine.  I saw some improvement of my symptoms initially but as time went by, they all returned. I became very frustrated and turned to the internet for information and advice.  I learned that gluten can damage the thyroid and asked my doctor if he thought I should go gluten-free.  His response: “It’s a gimmick”.  So, I continued to take my medication and feel miserable. The next spring, I decided to give up a carbohydrate-filled snack for Lent. Within 48 hours, I felt better than I had in a long time. It made me think about my diet, so I did some more research about gluten and decided to give it up to see if that helped. I jumped in head-first and implemented this into my diet and life. I was able to get off of the thyroid medication and my bloodwork has been great ever since. Continue reading

I have suffered for thirty years with various illnesses, including seizures and shaking, along with extreme anxiety. I was diagnosed with ME and bipolar. This was incredibly difficult for me, as I was a professional violinist and was forced to give this up due to these symptoms and my inability to use my hands.

Initially, I found out I had terrible blood sugar and realized I had a problem with carbohydrates. I then was diagnosed with gluten sensitivity as was most of my family.

I am now on a low-carb and very high-fat (but good fat) diet and continue to make other important changes, like eating more probiotics. I have fully recovered and today find myself in better health than when I was a child. I now play concerts again and am completely free from seizures, anxiety and lack of confidence!

Beyond this, I am a tall woman, measuring 5′ 8 1/2″, and have suffered from weight problems all my life. For a time, I was quite obese. I lost 77 lbs. and have now kept it off for years! I’m 47, but I look (so I’m told) and feel like I’m in my 30s!

Palmer K.

I was diagnosed with relapsing-remitting MS at 19, and for 26 years suffered the on-again/off-again awful symptoms of numbness, tingling, optic neuritis and profound fatigue. I had no idea that my chronic, mild digestive discomfort had anything to do with the MS. I just thought that it was normal to feel some digestive distress after meals. 

In the “dark ages” of the 1980s, before the Internet opened vast horizons of information, there were very few books on healing MS. I believed that what I ate might make a difference, and so I experimented with macrobiotic, vegetarian and low-fat food plans. I even tried the Swank MS Diet, an ultra low-fat approach. Nothing helped. In fact, the lower the fats and higher the grains, the worse I felt.

Finally, by 2010, I had educated myself enough to know that I needed help in finding the root causes of my MS. I decided to see a functional medicine nutritionist. Test results revealed that I had non-celiac gluten sensitivity (NCGS) and a “leaky gut.” Continue reading

My daughter began struggling with weight and depression while still a teenager. It took us nearly seven years to find out why: celiac disease. As we both experienced similar symptoms, but to varying degrees, we both began a gluten-free diet. She lost 30 lbs. In the past two years, and I finally went down about two clothing sizes – I was a size 12 (in jeans) and now am down to size 8!  I consider this a really great breakthrough!  It makes me feel super good to know my gut is healing.

I have a history of Alzheimer’s  disease in my family, as it has afflicted my mother, sister and several aunts. In my own life, I recently noticed that my recall for nouns is slipping and I couldn’t turn up the simplest of words. I decided to stop eating gluten. After two gluten-free weeks, I had a big bowl of pasta, got in my car and realized I couldn’t find my way to tai chi class. When I managed to get there I was unable to follow the form. It was really frightening. Later, I tried with a bowl of cereal and something similar happened. I tried following this elimination-style diet 3 more times with similar results. Now, I fully follow a gluten-free, low-carb diet. Two years after all that, and I can recall most words with only the occasional lapse in time.  I am so grateful.

Grain Brain was one of the first books I read when diagnosed with deadly brain cancer, and I truly believe it saved my life.

I was diagnosed with “terminal”, highly malignant brain cancer in 2013. I embarked on a highly therapeutic ketogenic diet to starve my cancer and boost the mitochondria of my healthy cells, with special help from my own “FARM”-acy. Today, three years later, not only am I alive, but thriving as my scans show no cancerous processes at all. An added benefit has been the complete reversal/elimination of polycystic ovary syndrome, Hashimoto’s Thyroiditis, breast fibroids, joint pain/arthritis, seasonal allergies and a very healthy amount of weight loss. My blood work shows massive reductions in inflammation markers, as well as blood sugar!

I’m sharing my journey with that hope that it will inspire others to follow this lifestyle protocol.

At the age of 31 I decided I was sick of being overweight with terrible IBS, rotting teeth and aching joints. I took it upon myself after, getting kicked off a theme park ride for being too big, to change my life around. I started researching different diets, beginning with Pete Evans’ Paleo Way program and mostly because of the interview with Dr. Perlmutter. After one year on a paleo lifestyle, I lost 50kgs and I’ve never been healthier! I am absolutely the model of health now. I surf with my 3 children and absolutely love living a healthy lifestyle. I couldn’t imagine eating any other way now!

Recently, I read Brain Maker. I quickly put the whole family on probiotics. The biggest change for me was I now no longer have migraines or psoriasis! That is what I wanted to share. I tell everyone about the book and encourage them to take a probiotic.

I am 85-year-old female, a retired nurse, and have followed Dr. Perlmutter since his very first book.

In 2005 I needed a cardiac cath. In 2006 I was diagnosed with MGUS and in 2007 I was diagnosed with Polymyalgia Rheumatica and Temporal Arteritis. These experience were my awakening. It dawned on me there was something wrong with the way I was living, eating, etc. I studied the cause of inflammation and knew I must go completely gluten-free, so I did. Beyond that, I am also dairy-free and regularaly fill my system with prebiotics and probiotics. I monitor my blood sugar to experiment with what I can eat without raising my BS above the limits. In all these years, I have not had a recurrence of my cardiac problems, nor PM and TA, and I attribute this entirely to these changes.

My whole life, all I’ve known is sickness. I started having regular nausea in junior high, along with vomiting and diarrhea. At age 29, I was 98 pounds and missing a lot of work. On top of that, I suffered from migraines. I worked in hospitals and had to go to emergency rooms to get IVs that would put me back on my feet.

Now I’m 55 and have been off gluten for four years. I have no more vomiting, food tastes better, and I am a normal weight of 120 pounds. I also have more energy. When I was eating gluten, I could not eat dairy; I am now able to tolerate butter and hard cheese. This change has truly changed my life!
