Ideas in this flowchart

• The bathroom scale is not useless, but it is the wrong tool to base motivation on.
• The measurement problem is that scale readings can change without reflecting progress.
• Scale noise comes from factors unrelated to progress.
• Water shifts and salt affect the reading.
• Sleep and stress affect the reading.
• The time of day and position in a training week affect the reading.
• The mechanics are covered in “why the scale does not tell the whole story.”
• The motivational problem is different from the measurement problem.
• Checking a noisy number daily trains people to feel judged daily.
• A lower reading can make someone feel unstoppable.
• A higher reading can make the whole plan feel broken.
• Neither reaction reflects reality, but both reactions drive behavior.
• Scale noise can lead to skipping sessions, slashing calories, or abandoning plans.
