Exposure to bright light synchronizes the central circadian clock in our brain, whereas proper meal timing helps sync the timing of different clock genes throughout the rest of our body. One of the most important breakthroughs in recent years has been the discovery of “peripheral clocks.” We’ve known for decades about the central clock—the…

The Evidence-Based Eating Guide The Evidence-Based Eating Guide: A Healthy Living Resource from Dr. Greger & NutritionFacts.org simplifies making the switch to a healthier lifestyle. It’s an easy-to-understand guide, bursting with information on eating more healthfully,…
The same meal eaten at the wrong time of day can double blood sugar. We’ve known for more than half a century that our glucose tolerance—the ability of our body to keep our blood sugars under control—declines as the day goes on. As you can see in the graph below and at 0:25 in my…
Grape juice and whole grapes are put to the test for brain function, including cognitive decline in early Alzheimer’s. In 2010, the first controlled trial was published that examined how the brain responds to grape juice. It helped aged rats, but what about people? “Concord grape juice supplementation improves memory function in older adults with…
Why are calories eaten in the morning less fattening than calories eaten in the evening? One reason calories consumed in the morning are less fattening than those eaten in the evening is that more calories are burned off in the morning due to diet-induced thermogenesis. That’s the amount of energy the body takes to digest…
Harness the power of your circadian rhythms for weight loss by making breakfast or lunch your main meal of the day. In my last chronobiology video, we learned that calories eaten at breakfast are significantly less fattening than the same number of calories eaten at dinner, as you can see at 0:14 in my video…
Raw garlic is compared to roasted, stir-fried, simmered, and jarred garlic. Garlic lowers blood pressure, regulates cholesterol, and stimulates immunity. I’ve talked before about its effect on heart disease risk factors, but what about immunity? Eating garlic appears to offer the best of both worlds, dampening the overreactive face of the immune system by suppressing…
A calorie is not a calorie. It isn’t only what you eat, but when you eat. Mice are nocturnal creatures. They eat during the night and sleep during the day. However, if you only feed mice during the day, they gain more weight than if they were fed a similar amount of calories at night.…
Given the power of chronotherapy—how the same dose of the same drugs taken at a different time of day can have such different effects—it’s no surprise that chronoprevention approaches, like meal timing, can also make a difference. The 2017 Nobel Prize in Medicine was awarded for “elucidating molecular mechanisms of the circadian clock,” our internal…
Dairy consumption is associated with years of advanced ovarian aging, thought to be due to the steroid hormones or endocrine-disrupting chemicals in cow’s milk. When it comes to the amount of steroid hormones we are exposed to in the food supply, dairy “milk products supply about 60–80% of ingested female sex steroids.” I’ve talked…
