Aniston is one of a number of celebrities who swear by intermittent fasting.
The actress discussed her penchant for the 'non-diet' diet—a style of eating that doesn't restrict what or how much you eat, but rather, when you eat—in a 2019 interview with Radio Times.
In it, she explained that she follows the 16:8 version of the diet, where she consumes her meals during an eight-hour window, while fasting for the remaining 16 hours.
