A January 2019 study at Okinawa Institute of Science and Technology Graduate University (OIST) and Kyoto University suggests that, “going without food may … boost human metabolic activity, generate antioxidants, and help reverse some effects of aging.”
One of the authors of the study, Dr Takayuki Teruya said, “Contrary to the original expectation, it turned out that fasting induced metabolic activation rather actively.”
A study by the G0 Cell Unit and Kyoto University researchers suggests that fasting, which puts the body in “starvation mode,” leads to fuel substitution, antioxidation, increased mitochondrial activation and altered signal transduction.
The study suggests that, “…during fasting, the tiny powerhouses running every cell are thrown into overdrive.”
