Can intermittent fasting help me lose weight?

Yes! Fasting alters how often you eat, which helps you eat less without counting calories or going on a diet. Intermittent fasting also encourages healthier, more conscientious choices around what you eat. Finally, intermittent fasting enables your body to tap into its fat stores for fuel so that you burn fat faster.

I like the app, but 80% of the time the main page is just two white squares. It isn't helpful at all! I checked for an update, but there is nothing. I'm going to try out a different app. Very frustrating! Update: switched over to Fasting Tracker. It does the same thing as Zero and actually opens! I really liked Zero when it worked, but I'm glad I found a suitable replacement. I will check back periodically to see if Zero corrects the problem, but I don't have high hopes.

Have been using paid version. As of today, cannot use the app at all: "This version of Zero is no longer supported. Please update to the latest version to continue using the app." I uninstalled/reinstalled, cleared cache - no change. It would be sad to lost quite a bit of data I've accumulated over the years. Hope the issue is fixed. Update: the bug was fixed

Keep me on track and a great reminder of when to begin my fed-state/fast-state. (5 stars) Updated Review: This app is no longer what it was. Whenever I want to begin or end my fast, the timer is no longer visible. I'd have to restart my phone for the timer to be displayed. The updates have made the app unbearable instead of useful. (1 star)
