Tom’s May Update

When I first started fasting, I’m not sure I would have even named it “fasting.” I cut out snacks after dinner and delayed or skipped breakfast, but I wasn’t especially regimented about it, nor did I do any overt tracking. With time and repetition, I saw success: I lost weight.

However, I didn’t lose all of the weight I wanted, so eventually I decided to get more fastidious. That’s when I started using Zero. With the app’s help, I began lengthening my overnight fasts to a full 16 hours and became more mindful about what I ate right before and right after my fasts. And what happened? I lost those final pounds.

Experience Converges with Science

Fast forward to mid-2023, when the Zero team convened to plan our next major feature. As we reviewed the scientific literature alongside the billions of Member data points we’ve collected, what stood out were those final hours of a fast — they appeared to be the key drivers of weight loss. Coincidentally (or perhaps not), this aligned with my own experience of losing those last stubborn pounds. The final hours of my fasts seemed to be what made the difference between hovering just above my goal weight and reaching it.
