Weight loss challenge rules: a template to copy 📋
📋 The template: 10 rules
Our weight loss challenge
1. Duration: We start on ___ and finish on ___ (for example after four weeks).
2. Starting weigh-in: Everyone logs their weight at the start. It is the basis for scoring.
3. When to weigh: Every morning, ideally after the bathroom and before breakfast.
4. Scoring: Whoever has lost the most in percent wins – not in kg.
5. Privacy: Everyone may keep their weight to themselves. We only compare the change.
6. Dropout: Anyone who logs nothing for three days in a row is out (K.O.).
7. Proof photo: A photo of the scale is optional, if the group wants it.
8. Stakes: If there are stakes, they stay small and voluntary.
9. Fairness cap: Only a limited loss counts per week, so nobody wins with a crash diet.
10. Finale: On the last day we tally up, celebrate the winner – and plan the rematch.
Copy the list into your group and adapt it. The only thing that matters is that everyone agrees beforehand.
💡 Why these rules?
Percent scoring evens out different starting weights. The privacy rule removes the fear of joining in. The weekly cap stops extreme dieting from being rewarded – slow, steady change is generally considered more sustainable. And voluntary stakes keep it a game.
🥊 How FatFight applies them
- Weighing: Everyone logs their own weight in the morning, for today only – missed days can’t be added later.
- Scoring: Leaderboard in kg or percent, the whole fight in percent only if you like.
- Privacy: If you want, the others only see your change.
- Dropout: Three days without a weight means K.O.; a photo of the scale is optional.
- Finale: A crown 👑 for the leader, then a rematch.
🤔 When are written rules enough?
For two disciplined people, the template in a shared note is plenty. As soon as someone has to collect and recalculate the numbers, it gets tedious. Rules also don’t replace consideration: with existing health conditions, pregnancy, eating disorders or any doubt, please ask your doctor first. A challenge is voluntary and nobody gets put on the spot.

❓ Frequently asked questions
Which rules does a weight loss challenge need at minimum?
Duration, weigh-in rhythm, scoring (fairest in percent) and how to handle dropouts. Everything else – stakes, proof photo, finale – is a bonus.
How long should a weight loss challenge last?
Four weeks or a month is popular because the goal feels within reach. Longer works too, as long as you plan milestones and interim standings.
What does the weekly cap mean?
In the FatFight Leaderboard and the Local Gym Fight, at most 3% per week is counted. That stops crash diets from being rewarded and keeps the competition healthy.
Does FatFight apply these rules automatically?
Largely: daily logging without back-filling, scoring in percent, a privacy option, the K.O. rule after three days and an optional photo of the scale. You agree on any stakes among yourselves.
