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.

At only 57 years old, I began to experience the onset of cognitive decline. Beginning at age 31, I suffered from epilepsy, and was also told I was prediabetic.  Today, with a low-carb, gluten-free lifestyle, my memory is functioning at an incredibly higher level. Yes, diet took away the whole problem! Better yet, my epilepsy and prediabetes have disappeared too!

One final perk? I have more energy than ever before!

For years and years, I suffered from daily migraines and physical pain. To manage this, I was taking several medications that, in the longer term, results in paralysis, a significantly worse health outcome than what the pills were intended to manage. Not only could I no longer feel the pain, but I couldn’t move my arms or hands either. I can’t find the words to express how debilitating this was for me.

Being gluten-free made all the difference. The pain and headaches are, finally, gone.

Over the last decade I have suffered from severe sleep deprivation and daily brain fog. That is, I did, until I learned about adrenal fatigue. A ketogenic diet has erased my symptoms almost entirely. I no longer need bottles of soda (and all that deadly sugar) just to get through the day. This was added relief, as I was, at the same time, being told I was prediabetic. No more do I fear falling asleep on long drives or at the dinner table!

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.
