Follow-up: Interpreting a composition change that is within the error bars

Outcomes › Body composition DXA lean mass loss bioimpedance data table

Solved

Solved by sterile_file in post #3

Maintenance phase: tracking body composition during maintenance (weight stable) is different from tracking during active loss. Changes are smaller and precision becomes more important.

Interpreting a composition change that is within the error bars Writing it up because I had to work it out twice and would rather nobody else did.

Longitudinal report with the method stated, because a number without a method is not a measurement.

Same scale, same time of day, same conditions, 78 weeks. I have also recorded protein intake and resistance-training sessions, both self-reported and both therefore optimistic.

The reason I am posting is a pattern in the middle of the series that I cannot explain and that I suspect is measurement rather than signal.

Precision versus accuracy: the precision you need depends on what question you are answering. "Am I losing fat?" requires less precision than "Is my lean mass preservation within the expected range?"
