One very popular variation of outright fasting is what is called time-restricted feeding (TRF). In both humans and laboratory animals, TRF refers the consumption of food only during a specific period of time each 24 hours. We know that this is certainly in contrast to the common way that people eat, meaning at least three meals a day with lots of snacks before, between, and after meals.
As it turns out, there appears to be quite a few health advantages to restricting the period of time that we eat during the day. Research has revealed, for example, how TRF positively affects a variety of cardiometabolic risk factors including blood sugar, and even the expression of our genes. Continue reading

Blood sugar elevation has become a central focus in medicine these days because of its well-established relationship to so many chronic conditions including Alzheimer’s, diabetes, obesity, and Parkinson’s. Now, new research reveals that there may well be a relationship to cancer risk as well.
Researchers at Johns Hopkins and Yonsei University in Seoul, Korea were interested in exploring possible relationships between blood sugar levels and risk for developing cancer. They studied a sample of over 1 million Koreans between the ages of 30 and 95 who had either a positive cancer diagnosis or had died of cancer. Their findings, published in the Journal of the American Medical Association, are quite remarkable and certainly instructive. Continue reading
It’s quite likely that very few people wouldn’t want to do everything they could to preserve the integrity and functionality of their brains. As it turns out, we, each and every one of us, have a lot to say about how our brains change over time.
We certainly don’t need to be reminded that persistent head trauma can pave the way for brain degeneration as we have seen with professional football players and others involved in contact sports. Further, there has been a lot written about the value of exercise in terms of a brain preservation program. Sleep, both its duration as well as its quality, has also gotten some of the spotlight as of late as we have begun to recognize how, during deep sleep, our brains are actually quite active in terms of ridding themselves of potentially damaging accumulations of various types of chemicals and debris.

While there has been so much attention as of late focused on infectious diseases, there is another epidemic that may have even wider implications—type 2 diabetes. In and of itself, diabetes is a significant life-threatening condition. In addition, it is strongly associated with other important and potentially life-threatening diseases like Alzheimer’s, stroke, kidney disease, coronary artery disease, and even cancer.
According to CDC data from 2018, some 34.2 million Americans, or 10.5% of our population, have diabetes. The percentage of adults with this diagnosis increased with age, affecting more than 25% of those aged 65 years or older. And clearly, the data indicates that these numbers are progressively worsening with time. Continue reading
By anyone’s definition, we must now consider Alzheimer’s disease to be an epidemic. Alzheimer’s is a progressive degenerative neurological condition that actually has its origins decades before the initial symptoms of cognitive decline begin to appear. Unfortunately, by the time these symptoms of the disease emerge—memory loss, cognitive decline, and behavioral shifts—there is very little that can be done as, according to our most well-respected medical journals, there is currently no meaningful pharmaceutical treatment for this condition. Despite this reality, pharmaceutical companies continue to market “Alzheimer’s drugs” to the tune of some $3-4 billion annually. Continue reading
Wow! Yesterday, the release of Grain Brain Revised, was an incredibly exciting day. From visiting with the folks at MindBodyGreen to taking your questions live in numerous live chats on Facebook and Instagram, I was privileged to get to spend the day speaking with you all and spreading our message on optimal health.
But it goes without saying that the most provocative part of my day was how it started — my conversation with CBS This Morning. Let me start by saying it was an honor to get to sit with such a storied team of reporters. It was humbling to have Gayle, John, and the entire team present for this dialogue.
We commonly think that if something is good for our health, that more of it is even better, right? More kale never hurt anyone. Putting on extra sunscreen may not protect us from even more UV rays, but it certainly won’t cause excess damage!
But is that actually always true? How about with insulin, which we’re commonly told to keep as low as possible? Continue reading
As we have explored previously, elevated blood sugar is clearly toxic for the brain. Higher blood sugar is clearly a risk for Alzheimer’s disease, along with coronary artery disease, diabetes, and even cancer.
But focusing on the brain, I think it’s important to emphasize that elevated blood sugar has wide-ranging negative effects on brain cells and their functionality. Elevated blood sugar is associated with inflammation, and this is a cornerstone mechanism across a wide spectrum of neurodegenerative conditions, including Alzheimer’s disease and Parkinson’s disease. In addition, persistent elevation of blood sugar ultimately compromises the function of the hormone insulin. We now recognize that insulin is important for the health and integrity of the brain not only because of its role in allowing glucose to be used as fuel, but also how it functions as a nurturing hormone.
