“Sugar substitutes are food products or additives that provide the sweet taste of sugar, without the calories. Evidence suggests that sugar substitutes have surprising effects on human metabolism and these effects vary person-to-person, based on the overall makeup of an individual's gut microbiome.”

“The benefits of HIIT include improvements in muscle tissue oxidative capacity, enhanced insulin response, improvements in heart function, and increased lactate – an important source of fuel for the heart, brain, and muscles.”

“Late-night eating can have negative effects on our health. But time-restricted eating limits the daytime window during which a person eats to take advantage of the time when metabolism is optimized, improving health and even promoting weight loss.”

“Time-restricted eating involves consuming meals within a specific daily time window. However, choosing the optimal time frame for that window is influenced by many factors, the most important of which is circadian rhythmicity, which alters our body's metabolic responses to food.”

“A four-week pilot study in people with type 2 diabetes reported improved insulin-stimulated glucose disposal after oral alpha-lipoic acid, while a three-week randomized trial found that intravenous 600 milligrams per day reduced diabetic neuropathy symptoms.”

“Circadian rhythms modulate a wide array of physiological processes, including the body’s production of hormones that regulate sleep, hunger, metabolism, and others, ultimately influencing body weight, performance, and susceptibility to disease.”

“Other hormetic responses to cold exposure include increased production of PGC1-alpha, a protein that promotes mitochondrial biogenesis, the production of new, healthy mitochondria, and the activation of brown fat – a phenomenon once thought to occur only in newborns, but now known to occur in adults, especially after cold exposure.”

“A critical element in healthiness is the timing and content of our meals. Time-restricted eating, a form of daily fasting wherein the time of the day during which a person eats is limited, capitalizes on the body's natural circadian metabolic rhythms to promote health.”

“Dom's efforts at teasing out the differences between induced nutritional ketosis (through a low carbohydrate, high fat diet) and ketosis from the dietary introduction of exogenous ketones, like beta-hydroxybutyrate, especially in the context of therapeutic and performance enhancing effects.”

“For example, growing up in an overly hygienic environment increases a child's risk for developing autoimmune diseases, but exposure to dirt, especially from soil, pets, and roaches, in the first year of life may provide protection against asthma and allergy-related skin disease.”
