Empty supports the following fasting types: 16-Hour Intermittent Fasting (16/8): Popularized by Hugh Jackman (Wolverine) as a efficient way to remove extra weight. 16/8 fasting means eating within a window of eight hours each day such as from 12pm to 8pm and not eating during the remaining 16 hours. It helps get us into the sweet metabolic state of fat burning called Ketosis. Circadian Rhythm Fasting: Based on the research of Dr. Satchin Panda, the confining caloric consumption to about 12-hour period as people did just a century ago.
