The Buddy System
A TransformationBuddy guide
The scale is noisy. The trend isn't.
Your weight can swing a kilo or more overnight without a gram of fat changing. Play with the simulation below and see why a 7-day average is the number worth watching.
A simulation with made-up numbers, to show the pattern. Not a prediction for your body.
What's going on
What moves the daily number
- Water: salt, carbs, heat and hard training all make you hold more for a day or two.
- Food still on its way through.
- Sleep, stress and hormonal cycles.
- The time of day you weigh in.
Weigh in the same way
Same time each morning, after the bathroom and before you eat or drink. Most days, or every day if it doesn't bother you: more points make the trend steadier. Then look at the line, not the dot.
Why seven days
A week evens out the weekend, the salty dinner and the long run. The average moves slowly, and only when something real changed. That's the whole point.
General information, not medical advice. If your weight changes quickly without explanation, talk to a doctor.
Let the trend do the worrying
TransformationBuddy draws your weigh-ins as dots and the 7-day trend as the bold line, so a bad Tuesday on the scale stays a dot.
