Track body composition (body fat %) alongside weight for a complete picture.
Use the suggested timeline to set weekly habit goals (nutrition, training, recovery).
If switching between metric/imperial, verify entries to avoid data entry errors.
Consult medical professionals before major weight changes, especially for underlying health conditions.
