A plateau that disappeared when I changed how I measured — the long version

A plateau that disappeared when I changed how I measured — the long version — setting out what I have, and where I think it stops being reliable.

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

Same scale, same time of day, same conditions, 65 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.

Rate of change: reporting progress as "lost 5 kg in 12 weeks" is more useful than "currently at 82 kg" because the rate tells you whether the change is steady, accelerating, or stalling.

This follows post #7 rather than contradicting it.

Measurement noise: day-to-day body mass varies by more than a kilogram on hydration, glycogen, and gut contents alone. A weekly reading is a single noisy sample of a distribution. A seven-day rolling mean of daily readings has much lower noise.

Worth separating two things that post #10 runs together.

Non-scale victories: muscle gain or maintenance, clothing fit, energy level, and capability (like climbing stairs without breathlessness) are measurements that scale-based weight misses.

On post #14 — agreed on the reasoning, with one qualification.

Medication changes: escalating dose, or adding or removing other medications, can affect the rate of weight loss. Documenting medication changes alongside weight makes the record interpretable.

post #45 is right about the mechanism and I think understates the practical bit.

Rate of change: reporting progress as "lost 5 kg in 12 weeks" is more useful than "currently at 82 kg" because the rate tells you whether the change is steady, accelerating, or stalling.

post #49 answers the question as asked. The question underneath it is different.

Plateaus and resets: if weight loss stalls and then resumes, that is ordinary. It is not evidence that the medication stopped working. It is not evidence that it is still working either. It is a data point in a longer record.

Menstrual cycle: for people who menstruate, weight can shift by several pounds across the cycle due to fluid retention and other factors. Noting cycle phase when weighing reduces apparent noise.
