It is worth asking what the claim would look like if it were false.

Pushing back on Dr.ObesityLA here. Not convinced. The evidence being cited is consistent with the conclusion and also consistent with two other conclusions nobody has ruled out.

One concrete data point for the thread. Give anything pharmacological four weeks before you judge it, and give anything measured weekly a four-point rolling average before you call it a trend.

Coming at LibrarianMeg’s question from a different direction. There is a difference between no evidence and evidence of no effect, and this subject is one where the two get swapped freely in both directions.

Correct me if the detail matters more than I have assumed.

Following on from zoe_NC — and this may be the naive question:

What did you change at the same time, and can you separate the two now?

Closing the loop on my own question.

Coming back a few months on. It held. Nothing dramatic to report, which is the report.
