I wanted to share my experiences with a low-carb, high-fat diet.

In January of 2014, at age 51, I weighed 185 pounds. At six-feet tall, I was not obese, but had a noticeable spare tire. at 6 feet tall but I had a noticeable spare tire. To make a change, I removed unhealthy foods from my diet, and replaced them with healthy fats like raw nuts and grass-fed beef, as well as increasing my vegetable consumption.

The first week I made these changes I lost 5 pounds. Major weight loss was never my intention, but I have lost an additional 25 pounds over the last year. Most startlingly, this is without any additional exercise (though I would probably be best served by changing that). There have even been gradual improvements to my memory and cognitive skills!

Martina was fed up with taking medicines for ten years that weren’t working, but she was afraid to quit. At the time she was taking an antidepressant, as well as a non- steroid anti-inflammatory for chronic pain in her arms and legs that had previously been diagnosed as fibromyalgia. In reviewing her history, I noted that she began to have issues with depression in her early 20s but hadn’t started medication until her mid 40s. She had been born naturally but not breastfed. She had been on multiple courses of antibiotics as a child for throat infections that culminated in a tonsillectomy. During her teenage years she had been placed on the antibiotic tetracycline for eighteen months because of acne. Bowel movements had always been a problem; Martina said she’d suffered from either chronic constipation or diarrhea for “as long as I can remember.”

My first order of business was to order some laboratory studies. That’s when I found out that she was significantly sensitive to gluten. Her vitamin D level was low, and her LPS level, again, a marker of gut permeability and inflammation, was sky high.

I was diagnosed with high cholesterol a couple of years ago, and was put on a statin drug. While I was on it, I was fatigued and “draggy” all the time…I even woke up fatigued!  Anyway, after hearing about the side effects of statins last year, I quit taking it. I changed my diet to vegan, hoping to become healthier and lose some weight. I lost 3 or 4 pounds and that was it. After several months of eating vegan, I had to have my cholesterol and triglyceride levels checked for my health insurance.  Imagine my shock when I was told that my triglyceride level was over 300, and my total cholesterol was 200!

On Memorial Day 2014, I made changes to my diet. I was particularly interested in the connection between high blood sugar and dementia, and that fasting blood sugar should be no higher than the low 90s for optimum brain function, so I decided to also keep track of my blood sugar levels. On day one of my grain-free eating, my fasting blood sugar was 116! For the next few days, my fasting blood sugar ranged between 103-108. The following week, it dropped down to the 90s, and I started to think, “That’s more like it!”  Now, my fasting blood sugar levels are consistently in the 70’s!  Continue reading

I was at a crossroads in my health situation. At 55 years old, I was still able to perform my daily tasks, including caregiving for a head injured foster son who is large. At night though, I could not sleep due to acid reflux, night sweats, anxiety, joint pain, and just general discomfort. I was cranky and angry because of my insulin resistance. My mood swings had my family in discord.

In 1989, I had a surgery on an artery in my leg. Doctors told me then that I had an autoimmune disease that affected my tissues. This disease would sometimes flare up and cause extreme bruising. I was foggy minded and my nose ran all the time. I knew that I had to do something about my weight and my health (I weighed between 210 and 220). Even though I was physically strong, I felt sick and weak a lot of the time.

In February of 2014, I was awake again late at night. I saw the show called “Brain Change” featuring Dr. David Perlmutter on PBS. Since I have a brain injured foster son, I was interested in any show about brains. As I watched the show, I realized that the subject matter was more relevant to me and to my situation. The longer I watched Dr. Perlmutter, the more excited I got. Finally, I understood the connection between the glycemic index and my inability to keep weight off. I could see that what my diet was missing was essential fats and healthy balance. According to Dr. Perlmutter, I could eat an abundant amount of the right foods, and still lose weight and regain my health.

I was so excited that I could not sleep. The next morning, I ran out and bought coconut oil, some organic canned sardines in olive oil, and some cacao dark chocolate. I printed up a glycemic index of foods, and went shopping for those that were under 30. I began to feast on the foods that would nourish me. I got all of the sugar—and most of the carbohydrates—out of my diet. My energy level shot up. Within a week, I lost 7 pounds.

I am 52 years old and am currently taking Cymbalta, 30mg for depression. I have been seriously depressed for too long along with severe anxiety.

Only one month after becoming gluten free, and reducing my carbohydrate and sugar intake, I am a totally different person. Honestly, it is like night and day. My anxiety has disappeared; I am calm.  I’m not depressed. Instead, I’m feeling good and content. I used to think that I would be on antidepressants forever, but now I feel like there’s hope that one day I won’t need them anymore.

I began suffering from depression in my mid 20s. This condition affected the path of my life as I was unable to function for months at a time. I was on antidepressants all through my 30s, trying cocktail after cocktail only to suffer terribly from side effects. Towards the end of my 30s I developed a gluten intolerance and tried to avoid gluten (with only moderate success!). I was completely addicted to sugar, gluten and carbs. I was also horribly addicted to sugar. My point is, my carb, gluten and sugar addiction was a long struggle.

I read Grain Brain at the beginning of January 2015 and immediately implemented a low-carb, high-fat diet. Literally within about a week, I noticed a complete turnaround in my general energy level. The brain fog is completely gone.  I don’t know what is more astounding: the fact that I feel so awake and energetic, or the fact that I am no longer ruled by cravings for carbs and sugar. It is hard to keep my story to myself! I want to tell everyone I know – “STOP EATING CARBS!!”

No carb tastes as good as being energetic and awake.

Here in Alaska we watch grizzly bears chow down on blueberries like nobody’s business each fall. I used to wonder how berries could help bears put on fat, as I had thought you needed fat to put on fat! Then the pieces came together!

I often forget why I walked into a room, and I experience a triggered memory begin to follow a synaptic path at times to have it disappear into a nebulous nothing.

I am not considered overweight, but could feel visceral fat inside after menopause. Now, I am very happy to include plenty of fat in my diet and in even just 5 days, the extra body fat is melting off and I am understanding my symptoms must have been due to a long-term, undiagnosed gluten and dairy sensitivity.

After turning 50 I started “falling apart.” I had already been diagnosed with hypothyroidism, and my memory was failing me, even though it had always been sharp. Arthritis and carpal tunnel syndrome were increasing and causing me a lot of joint pain. The worst health issue I was experiencing was allergies to everything!

Since reading Grain Brain I have lost 16kgs, gained lean mass, started resistance and conditioning training, and generally had a “lifestyle change” for the better.

I found that with previous diets, such as Atkins, I mistakenly ate too much protein and not enough fat, nor was I incorporating exercise. After initially losing a lot of weight, most of it would be put back on once the diet had “finished.” Now I realize that eating and exercise habits need to change if the weight is to stay off for the long-term. Going low-carb for me actually meant I had more energy than before, therefore doing exercise was less of a chore. I actually wanted to get out and run, bike, and walk, that was a first for me!

I now feel and look (so I’m told) about 10 years younger, am the fittest I have ever been and look forward to a more active and healthier lifestyle in the future, all with lots of lovely fat!

I appreciate the role word-of-mouth has played in the story of Brad and those around him. It’s amazing to see how these principles get shared with others and are used to cause health. – Dr. Perlmutter

I am 61 years old. For four years I have intensely trained for Nordic ski racing with steadily improved success. When I started training, I weighed 185-190 lbs., with a BMI of approximately 15-16%. My weight dropped to 178-180 lbs., but plateaued there for three years.

Recently, my daughter, who is a personal trainer, began to persuade me of the value of your work and research, leading me to pick up a copy of Grain Brain.

After reading your book, my wife and I restructured our nutritional approach, following your guidelines. My weight is now 165 lbs. with a BMI of 10-11%. I am now training with greater efficiency, and faster recovery times.
