“Hormones involved in appetite regulation showed no consistent response. Leptin (a hormone that also reflects energy stored in body fat) was modestly higher with shorter sleep, but two other appetite-related hormones, GLP-1 and ghrelin, did not clearly change.”

“Poor sleep reduces the body's insulin sensitivity and changes a person's appetite, increasing the preference for high carbohydrate foods like pizza, pasta, and sweets. Lack of sleep also alters the gut microbiota and impairs immunity, putting us at risk for developing acute illnesses like colds and flu.”

“Human data associate circulating AGEs with aortic stiffness in hypertension, but this does not prove that short sleep caused the AGE burden or that lowering HbA1c reverses cardiac aging. Sleep loss also changes leptin, ghrelin, hunger, and preference for energy-dense foods.”

“Researchers in Dr. D'Agostino's laboratory observed a decreased tumor burden and enhanced survival in animals that were provided a ketone supplement, even if they were fed a high-carbohydrate diet.”

“Dr. Panda discusses the effects of time-restricted feeding on systemic inflammation; time-restricted eating as an opportunity for night-time repair that may prevent intestinal hyperpermeability (i.e., leaky gut), a primary source of systemic inflammation; and how the timing of macronutrients may differentially affect gut permeability.”

Dr. Rhonda Patrick discusses resistant starch, red light therapy risks, stem cells, and the link between benzodiazepines and dementia in her latest Q&A session.

“In a randomized trial of 80 adults with overweight who usually slept fewer than 6.5 hours, counseling increased sleep by about 1.2 hours per night and reduced objectively measured energy intake by approximately 270 calories per day over two weeks.”

“These changes drive processes that improve cellular respiration, reduce inflammation, enhance memory, and provide protection from cancer – critical aspects in slowing the effects of aging and promoting longevity. Part II of this three-part Aliquot features Dr. Dominic D'Agostino, an expert in ketosis; Dr. Eric Verdin, an expert in aging; and Dr. Valter Longo, an expert in gerontology.”

“In a short intervention in 29 healthy young men, a daily sugar-sweetened beverage increased fasting glucose, C-reactive protein, and atherogenic LDL features within three weeks; this was a biomarker study, not a cancer trial.”
