Quit junk food with a commitment people can see

Why cutting out junk food is so hard to keep up

Consuming junk food typically happens in private: the drive-through on the way home, the snack drawer at work, the bag of chips after everyone’s gone to bed. When nobody sees it, “just this once” costs nothing, and one slip quietly turns back into the old routine. A private tracker doesn’t change that, because you’re still the only one who knows.

PublicHabits changes that. When people who know you can see how many days you’ve gone without junk food, “just this once” stops being a secret, and every day you hold out counts for something.

How to set up a public commitment to quit junk food

1. Create a bad habit. Add a habit like “Junk food,” “Fast food,” or “Late-night snacking,” and choose Bad habit. Instead of a streak, PublicHabits counts your days free.
2. Write your public commitment. Be specific about what counts (e.g. “No fast food or candy 6 days per week”). It appears on your page, and if you change it later, a dated note records the change, so you can’t quietly move the goalposts.
3. Log any slip-ups. If you have junk food, log it and add a comment about what happened if you want. Your days-free count starts over, and you’re right back to building it.
4. Share your link. Turn on sharing and send your link to a partner, share it with friends and family, or post it in your social media bio. They see your days free and calendar in any web browser (no signup or app download required).

Why counting days free works

Every day without junk food adds to a number people who know you can see. The longer it gets, the more it’s worth protecting, and the harder it is to throw away impulsively. People behave differently when they know they might be observed. Psychologists call this the Hawthorne effect, and it’s why a number other people can see beats one only you can see.

What your page shows

People with your link see your display name and each habit, including:

• Your days free: how long it’s been since your last slip-up
• A calendar with each slip-up marked
• Your public commitment, and a dated note if you ever change it
• Any comments you added, like what triggered a slip-up or a milestone you hit

A slip-up doesn’t erase your progress. Your count starts over, but your history stays on the page, so the people watching see an honest record of you getting back on track.

Examples of public junk food commitments

• No fast food: “No fast food for 30 days.”
• Weekday rule: “No junk food Monday through Friday.”
• Late-night snacking: “Nothing to eat after 9 pm.”
• Sugar: “No candy or sugary drinks this month.”
• A limit: “Junk food at most once per week.”
