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.

Ratings and reviews

I like the interface, but there's several things that seem to be broken in the Free version. For example, streaks & milestones are not being earned or incremented. Also, the week view for the Total Fasting Hours chart is not accurate. It has not shown anything since 10/28 and the hours that are displayed for that day do not even reflect what was recorded for the fast itself. -- If you don't care about any of that stuff and just want to track your fast each day, the Today & Calendar views work.

The mood journal still seems to be hit and miss, same for meal entries. I am not going to pay to get better things. I can do my meal logging on Atkins at no charge, with many foods built-in to the app. But tracking my fasts is the primary reason for using it. Keeps me motivated when I look at the calendar for all my fasting data. That's a huge perk along with the challenges. **edit, 10/29/24** You've helped me a great deal to get thru some extra tough times in my journey, but I'm finally there!

Update.. 8/30/24 In an attempt to extort money through the increasingly popular 'subscription model', the app no longer allows you to see your weight data in anything except the week view. The monthly and yearly view is hidden behind the pay every month wall. Don't get me wrong, I would certainly pay a ONE TIME FEE for this app... But that isn't what they want.. They want to sell you a 'service' so you get to keep paying every month.. No thanks
