Fasting Wrapped 2025
“breakfast is the most important meal of the day”
— some cereal company marketing department, probably
spoiler alert: i didn’t die.
ive been doing OMAD (one meal a day) since covid. the science behind intermittent fasting is interesting — autophagy, metabolic flexibility, insulin sensitivity, blah blah — but tbh the main reason i do it is simpler: fewer decisions. no breakfast to think about. no lunch to coordinate. just dinner. done. back to work.
this is my spotify wrapped for not eating lol
2024 vs 2025
| Metric | 2024 | 2025 | Δ |
|---|---|---|---|
| Days Tracked | 366 | 298 | -68* |
| Success Rate | 99.2% | 99.7% | +0.5% |
| Average Fast | 21.7h | 22.5h | +0.8h |
| Best Streak | 214 days | 230 days | +16 |
| Total Hours | 7,927h | 6,704h | -1,223h* |
*2025 data starts from Feb 26, not full year (switched tracking apps, long story)
the numbers got marginally better. 0.8 hours doesnt sound like a lot, but compound that over 300 days and suddenly you’ve fasted an extra 240 hours. thats 10 full days of additional not-eating. the streak improvement is more impressive — 230 consecutive days of hitting the 16h+ target. from late february through late october. 7.5 months without a single miss.
distribution shift
the whole curve shifted right. the peak moved from ~21h to ~22h. the variance also tightened slightly. more consistent.
monthly trends
patterns that emerged:
- february high — probably bc of extended fasts during that month
- june dip — both years. travel? social events? unclear
- Q4 consistency — oct-dec in 2025 was more stable than 2024. muscle memory maybe, parents cooking maybe
day of week
no weekend effect. saturdays and sundays are just as consistent as weekdays. this surprised me honestly — you’d expect social events to mess things up. but nope. the habit is habit-ing.
2025 deep dive
github-style heatmap
green = 16h+ fasts. darker = longer. purple = the 24h+ full-day fasts. if contributions were calories not consumed, i’d have the most active github in the game.
daily scatter
each dot is a day. orange line is 7-day rolling average. purple vertical lines r full-day fasts. mostly religious observances (yom kippur) plus a few random ones when i just… forgot to eat. it happens.
streak tracker
230 days. thats the longest streak — from late feb through late october. beat last years 214 by 16 days. the only reset came from getting sick and forgetting to add the times.
cumulative hours
6,704 hours in 2025 combined with 2024’s 7,927 hours, is 14,631 total hours of fasting. or put another way: 610 days. 1.67 years of cumulative fasting packed into 2 calendar years.
when people ask “how do you have time for X” the answer is partially this. no meal prep. no dishes (mostly). no food decisions ~22 hours a day. that time goes somewhere.
monthly breakdown
every month hit near-perfect success rate. the stars mark months with 24h+ fasts.
eating window
start meal: 7-8pm. end meal: ~10pm. 2-3 hour eating window. this hasnt really changed. dinner time is dinner time.
the 24h+ club
five full-day fasts in 2025:
- july 25 (random; just didn’t get around to eating)
- august 7 (same)
- september 11 (no affiliation)
- september 30 (yom kippur eve)
- october 1 (yom kippur)
the longest single fast was 68 hours in 2025 vs 49 hours in 2024. +39%. thought itd be too ‘easy’ to do a normal 24h fast for YK so i did an extra ~2 days lol
2024 data extracted from Zero app. 2025 data tracked manually (spreadsheet gang) from Feb 26 through Jan 1. visualizations made with python/matplotlib bc im a nerd.
heres to another year of feeding the flesh suit. 🍽️
