Autophagy starts when the body is under certain stress conditions such as calorie restriction, exercise, and fasting. This is where autophagy comes in: It helps to clear damaged cells from the body, including senescent cells that serve no functional purpose but still linger inside tissues and organs. Furthermore, these eating patterns can cause low blood sugar levels, which may also contribute to fatigue (17, 18, 19). They recommend fasting for anywhere between 16 to 18 hours a day to reap the benefits. Even in a healthy human body, cells are constantly becoming damaged as a normal part of metabolic processes.
