“Prolonged fasting stimulates autophagy, an intracellular degradation system involved in the disassembly and recycling of unnecessary or dysfunctional cellular components. Autophagy is thought to be part of a coordinated biological process that is important for exposing cancer cells to the immune system, ultimately leading to their weakening and death.”

“Although there may be differences in how men and women respond to time-restricted eating, Dr. Panda feels that most people can include time-restricted eating of 12 hours, with the exception of pregnant or breastfeeding women, and people with type 1 diabetes.”

“However, the day after cold exposure, the men had decreased fasting triglyceride levels and very low-density lipoprotein levels, suggesting that cold exposure may exert long-term beneficial alterations in lipid metabolism.”

“Researchers measured BDNF levels after fasting, light exercise, or vigorous exercise in healthy, physically active adults. Participants fasted for 20 hours, engaged in light cycling (90 minutes at 25 percent VO2 max), or engaged in vigorous cycling (six 40-second bursts at 100 percent VO2 max interspersed with 20 seconds of light cycling).”

“Then they performed fMRI scans on 12 young adults (average age, 28 years) to assess how different energy sources – glucose versus ketones – alter brain function. Each participant underwent three scans under different dietary conditions: a normal diet without fasting, a normal diet with overnight fasting, or a ketogenic diet for one week.”

“Many of the cellular pathways involved in sulforaphane and curcumin detoxification are shared with exercise and fasting, suggesting a shared health benefit to these seemingly unrelated hormetic stressors.”

“When cellular energy levels are low, such as during exercising, fasting, or caloric restriction, the ratio of NAD+ to its reduced form, NADH, increases, thereby serving as a "sensor" to switch on sirtuin expression and subsequent activity.”

“Addressing key factors such as diet, inflammation, insulin resistance, exercise, intermittent fasting, and sleep optimization seem to be most promising for preventing Alzheimer’s disease and slowing its progression.”

“Perhaps more compelling was the discovery that engaging in exercise or fasting or other healthful activities actually triggers the activity of these genes to prolong lifespan. Much of this research was conducted in yeast or worms – lower organisms whose lives were favorably impacted by the research and who, in turn, impacted the lives of the scientists who studied them.”

“Low energy levels, such as those that would occur during exercising, fasting, or caloric restriction, stress the cell. In turn, cellular levels of nicotinamide adenine dinucleotide, or NAD+, a coenzyme that participates in the production of cellular energy, rise, switching on energy-generating pathways and activating enzymes such as sirtuins.”
