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.

Today on The Empowering Neurologist I had the pleasure of again spending time with Dr. Matthew Phillips. He’s been on the program in the past discussing the effectiveness of the ketogenic diet in Parkinson’s disease.
Today he explores the notion of fasting, and reveals how powerful a therapy this may represent as it relates to both keeping the brain healthy as well as in the treatment of existing disease. Continue reading
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
There’s so much information that we are exposed to day in and day out focused on what we should be eating. But lately there seems to be an important shift in the conversation to trying to understand when we should eat. Truthfully, we had always thought that to be healthy we should be following the “three meals a day” rule, with special emphasis on breakfast since it was thought to be “the most important meal of the day.” But, gratefully, well-respected researchers are now challenging these ideas.
