Related Episodes for Sleep, Daylight Anchoring, and Effects on Memory & Obesity with Dan Pardi

“A common feature of heart disease is arrhythmia, an irregular heartbeat. Interestingly, research in fruit flies has shown that unhealthy lifestyle behaviors, such as poor sleep and diet, increase the risk of developing arrhythmias.”

“In the modern world, there is an evolutionary mismatch concerning light exposure. Many people are indoors during the daytime where they are not exposed to bright light, while artificial lighting allows light exposure during the night.”

“Bright light exposure has a profound effect on regulating the circadian system in humans. Dr. Panda and colleagues discovered that melanopsin — a light-sensitive protein found in specialized cells of the eye — responds to blue light and synchronizes the body's day/night cycle.”

“Longer-term nutrient status offers another perspective: in a randomized trial of adults with overweight or obesity, 15 grams of psyllium daily for three months did not significantly alter serum micronutrient concentrations relative to control.”

“If you have used a consumer genetic testing service like 23andMe or AncestryDNA and want to learn more about whether or not the data indicates your specific genotype on these SNPs, check out our free viral report here.”

“A recent meta-analysis also found small benefits in selected cognitive domains, including memory and processing speed, with responses that may depend on age, diet, baseline stores, stress, dose, and the cognitive test used.”

“A separate six-week randomized study in 30 healthy young adults found that neither 10 nor 20 grams per day improved the tested cognitive outcomes compared with placebo. The result is an important counterweight to the acute sleep-deprivation experiment.”

“Acute stress may create a different context. In a double-blind crossover study of 15 adults undergoing 21 hours of sleep deprivation, a single 0.35-gram-per-kilogram dose changed brain high-energy phosphate measures and improved selected cognitive outcomes.”

“Dr. Patrick then prioritizes lower-glycemic-load, less-refined foods and adequate fiber. Early time-restricted eating can help some people reduce calories and may influence selected metabolic markers, but it is not required and must still preserve protein and diet quality.”

“This effect, sometimes called the 'afterburn effect,' does have some scientific basis, according to recent podcast guest Dr. Martin Gibala. In scientific terms, it's known as EPOC or Excess Post-Exercise Oxygen Consumption.”
