Waist circumference technique and its repeatability

Waist circumference technique and its repeatability — setting out what I have, and where I think it stops being reliable.

I have spent a fortnight trying to pin waist circumference technique down and I want to set out where I have got to, because I suspect the honest answer is duller than the thread this will produce.

What I have: a consistent observation across a small number of cases, collected the same way each time. What I do not have: any controlled comparison, or any reason to think my cases are representative.

The specific question is whether the pattern survives once the obvious confounder is removed. I cannot remove it with what I have.

Nothing here is medical advice and a progress report is a description of what happened to one person under uncontrolled conditions.

A note on how waist circumference technique gets discussed rather than on waist circumference technique itself: the confident posts get the replies and the careful ones get ignored, and the careful ones have been right more often.

Waist circumference technique came up in a thread eighteen months ago and was answered well. I cannot find it, which is itself the problem, so here is the reconstruction.

Rate of change matters more than the absolute number for most of the questions people ask about their own series.

Appreciated. The plain phrasing does more work here than a longer post would.

Checked the waist circumference technique claim against the primary source this morning. It survives, with a narrower scope than the version quoted here. Posting the narrower scope.

Post #7 answers the question as asked. The question underneath it is different.

Reporting rather than recommending, on waist circumference technique. What happened is above. Whether it should have is a different question and not one I am qualified to answer.

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.

Worth checking against a second source before it gets quoted onward.

This follows post #7 rather than contradicting it.

I have three months of notes on waist circumference technique and the honest summary is that the trend is real and the week-to-week numbers are noise. I nearly drew the opposite conclusion from the first fortnight.

This follows post #8 rather than contradicting it.

Trying to state the waist circumference technique position in a way that someone who disagrees would recognise as fair, because I do not think the version in this thread passes that test.

A single scale used throughout beats a more accurate scale introduced halfway through. Consistency beats accuracy for a trend.

I keep a log of this specifically because memory is unreliable about it.

Seconded. It reads as careful rather than confident, which is the right register.

Waist circumference technique is worth one more sentence than it usually gets, and the sentence is the one about how the number was arrived at.
