Empty is a simple and intuitive fasting tracker used for Intermittent, Circadian Rhythm, and Custom fasting. Choose your favorite fasting type and Empty will track and remind your ongoing progress. 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. It helps staving off high cholesterol, diabetes and obesity. Custom Fasting: Setup a custom program to meet your fasting goals. You choose your fasting hours per day, and days per week.
