オートファジー

• 読み: オートファジー
• ローマ字: ōto fajī
• 漢字の分解: From Greek auto (self) + phagein (eat) → 'self-eating,' the cell's self-cleaning mechanism
• 発音: /oː.to.ɸa.dʑiː/

意味

Autophagy; the body's cellular self-cleaning process, popularized as a buzzword linked to fasting and anti-aging.

オートファジー became a sensation in Japan after Yoshinori Ohsumi won the 2016 Nobel Prize in Physiology or Medicine for his research on autophagy mechanisms. The scientific concept was quickly adopted by health media and fasting advocates who claimed that 16-hour fasting activates オートファジー, promoting cell renewal and anti-aging. While the science is real, the mainstream usage often oversimplifies the process, treating it as a magic bullet triggered by skipping meals.
