Time-restricted eating is likely a familiar concept to those of you who participated in our Summer Fasting Challenge. Time-restricted eating, often termed time-restricted feeding (TRF) in scientific literature, is a form of intermittent fasting that restricts consumption of foods and beverages—“energy intake”—to a specific window of time. For example, as we did together in the Summer Fasting Challenge, 18:6 TRF signifies a 6-hour eating window and 18 hours of fasting.
As we discussed during the Summer Fasting Challenge, and as I have written about in recent blogs, it’s clear that there are health benefits to time-restricting our food consumption. In the realm of scientific literature that supports this notion, a study published in the journal Nutrition Reviews is no exception. This study offered a summary of evidence on the effects of time-restricted feeding on both body weight and markers of metabolic disease risk. The authors of this review looked at 11 human studies and 12 animal studies. Both categories of studies included various TRF eating window durations, ranging from 3-4 hours to 12 hours.

I have to shake my head when I still see “egg white omelet” on the breakfast menu at restaurants. Gone are the days when I would ask the waiter or manager why this was offered. Over time I realized that it wasn’t their fault. They were simply parroting the standard dogma that eggs were bad for your heart – especially the yolks with their high levels of “artery-clogging cholesterol” and all.
For decades, we were instructed that dietary fat was virtually kryptonite. And of all the dietary fats we might consume, cholesterol was by far the biggest threat. Continue reading
You may or may not have seen the American Heart Association’s (AHA) latest report, but I’m sure you’ve probably seen the social media frenzy that followed their statements on coconut oil.
An article by USA Today with the headline “Coconut Oil Isn’t Healthy, It’s Never Been Healthy”, has been shared over a half a million times. The AHA rehashed their age-old dietary guidelines for fats and cholesterol, attempting to finger them both as the cause of cardiovascular disease (CVD). But this time they took it one step further and took a stab at coconut oil, stating:
However, because coconut oil increases LDL cholesterol, a cause of CVD, and has no known offsetting favorable effects, we advise against the use of coconut oil.
So what’s going on here? Is coconut oil suddenly not as good for you as we once thought? Or, is the AHA report based on erroneous science? Continue reading
Recent reports continue to find an adverse relationship between Type 2 diabetes and the risk of Alzheimer’s, with diabetes shown to increase the risk of an Alzheimer’s disease diagnosis.
In light of this, it would make sense that we do everything we can to prevent the development of diabetes in our own bodies. That’s why it’s troubling to hear about new research that demonstrates that one of the most commonly prescribed classes of medications, statin drugs (used to lower cholesterol), has a profound impact on the chance that someone could develop Type 2 diabetes. Let’s dive into this research today. Continue reading
We are seeing ever-increasing efforts to make us believe that lowering our cholesterol is always going to be a risk-free event…and these efforts are working. Statin drugs to lower cholesterol have become among the most popular medications in the country!
But it’s really important to see what our most well-respected scientific journals are telling us about these drugs. In a meta-analysis study, researchers found that those individuals taking what were considered “higher dosages” of statin medications had more than a 50% increased risk for bleeding in their brains (intracerebral hemorrhage).

I don’t think there’s any more controversial food than eggs. By and large, the reason we have been told to avoid eating eggs is because they contain cholesterol, and indeed that’s true. A typical egg may contain as much as 200 mg of cholesterol. But does that mean we shouldn’t eat eggs?
To answer this question, researchers in Finland conducted an extensive study in which they evaluated two parameters. First they looked at whether or not individuals developed coronary artery disease. In addition, they looked at a parameter called carotid intimal thickening. Basically this is a study, using ultrasound, that looks at the thickness of the lining of the carotid artery. The reason this is used is because it is a strong indicator of coronary artery disease if in fact there is thickening.
