At 57 years-old and 460lbs, my father passed away. Watching this happen at 40, I knew I needed to turn my life around. Grain Brain, and a ketogenic lifestyle, did that for me.

I went from 360 lbs. to ~250 lbs. in a couple years. I started with a modified keto diet, but as I saw results I continued to improve over a 3-year period to reach the optimal keto diet I am currently on, which is low-fat, high-protein, and extremely low-carb diet. As a lifestyle change, I have combined this with intense strength training. I feel 18 again, and can keep up with anyone else in the gym without needing carbs. I recover exceptionally well and my joints feel great. Best of all, my body is dropping fat fast. I’m almost in a size 34 jean now at 258 lbs.

I eat very clean, organic protein, lots of spinach, broccoli, asparagus, etc. I enjoy grass-fed beef, properly raised and fed chicken, and have been adding more fish to my diet as well. Never eat any wheat/gluten, ever.

5 Things We’ve Learned Since The Release of Grain Brain

Five years ago today, we embarked on an incredible journey. Together, we sought to understand the roots of brain health, and how we can help fend off ailments like dementia and Alzheimer’s, diseases for which there are no known cures. This journey began with the release of Grain Brain.

In the five years since, science has continued to investigate the roles carbs and gluten play in our health, and our message has moved to the mainstream. As a result, the information in Grain Brain is now accompanied by ongoing changes and revelations in the world of medicine. Today, I want to share with you the five most interesting things I’ve learned/seen since Grain Brain hit shelves. Continue reading

The Empowering Neurologist – David Perlmutter, MD and Dr. Sarah Hallberg


Do medications “treat” type 2 diabetes? The answer is “no.” While there is a fairly robust list of drugs commonly prescribed by physicians for this situation, these pharmaceuticals tend to treat only the consequences of the disorder, like elevated blood sugar.

In this segment of The Empowering Neurologist,  I have the great pleasure of interviewing one of the most forward thinking experts in diabetes in the country, Dr. Sarah Hallberg. This is her second time on the program, and with good reason. She and her team have just completed a study in which they demonstrate profound success in actually treating diabetes using a closely monitored ketogenic diet. Continue reading

The Empowering Neurologist – David Perlmutter, MD, and Dr. Valter Longo


There is clear scientific evidence that supports the idea that lifestyle interventions like caloric restriction, fasting, and a ketogenic support the health of positive gene pathways, enhance the production of endogenous stem cells, power up the brain, increase the production of antioxidants, and even reduce inflammation.

But there is no doubt that implementing these ideas, in terms of creating a workable diet, may well prove challenging.

Our guest today on The Empowering Neurologist is Valter Longo, PhD. Dr. Longo has created a new dietary approach that in many ways mimics the effectiveness of the more difficult approaches described above, but at the same time is much easier to implement. He calls this diet the Fasting-Mimicking Diet, or FMD, and it is described in great detail in his new, best-selling book, The Longevity Diet. Continue reading
