The Science of Switch On

Resilient Nutrition

THE RATIONALE BEHIND SWITCH ON A huge number of us don’t look, feel or perform our best because we don’t routinely sleep well. There are many forms of sleep problems. Some sleep issues are common, such as recurrent sleep restriction (not getting as much sleep as needed) and “social jetlag” (shifting sleep times between workdays and work-free days). Other sleep problems are more debilitating, however, and these include 6 broad categories of sleep disorders (insomnia, circadian rhythm sleep-wake disorders, sleep-related breathing disorders, sleep-related movement disorders, parasomnias, disorders of hypersomnolence). Perhaps unsurprisingly, some sleep problems have been exacerbated by COVID-19 lockdowns....

What Happens to Your Body When You Go Without Food?

Greg Potter

Many of us are in privileged positions: Whereas it was presumably common for some of our ancestors to experience famine, nowadays food is so abundant that people deliberately fast for extended periods for health benefits. This practice is rooted in science, for intelligent use of fasting can be therapeutic. The punctuated stress of fasting can trigger myriad adaptations that bolster resilience, protecting against a range of future stressors, and people can successfully use fasts of 5 to 21 days multiple times within a single year. We should not take our good fortune for granted, however. The Ukraine War, climate change,...

Greg Potter

Now and then, you don’t get enough sleep. When that happens once, it doesn’t affect you much.

Eat Chocolate, Be Smarter? What You Should Know About Cocoa and Brain Health

Greg Potter

Let’s face it, I’m a chocoholic. So, when it came to exploring the science of cocoa products, I was bound to be a bit biased. But as I fought my urge to cherry pick research supporting the health benefits of cocoa, I came to see that it really is highly nutritious. However, there’s also a dark side to cocoa (pun intended) that has implications for which cocoa products you should pick. In the next couple of blogs, I’m going to highlight the science of cocoa, beginning with how cocoa affects brain health and the best ways to consume cocoa for maximum...
