Kevin Rose has been sharing his biohacking experiences with Tim Ferriss and Ben Greenfield. Kevin also puts out a monthly journal “The Journal by Kevin Rose” which highlights things that catch his eye. His latest journal includes an app that he brought into the world called Zero. It aids people who are fasting by offering specific sunset times to sync eating with your circadian rhythm. You can also use custom intermittent fasting durations or pick two days a week for reduced caloric intake.

Meet my new app, Zero (named for the amount of food you eat while fasting). Zero was created as an easy way to track and log fasting data over time.

Aside from tracking daily start and stop times, Zero also helps track nighttime eating. It does this by fetching your location to calculate local sunset time. For example, if the sun sets at 6pm, and you began fasting at 8pm, Zero would automatically log two hours of nighttime eating.

Why fast? Why does nighttime eating matter?

All the benefits of fasting are covered in a wonderful video series by Dr. Rhonda Patrick, where she interviews scientists Dr. Valter Longo, Dr. Satchin Panda, and Dr. Ruth Patterson. I highly recommend that you watch all three of these videos if you’re new to fasting.

Zero is available for download now and is free (iOS, sorry no android at the moment).
