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.

Coming at Dr.BariatricHTX’s question from a different direction. Take it one variable at a time. Almost every unanswerable question in these threads is unanswerable because three things changed in the same fortnight, and no amount of subsequent argument can untangle them after the fact.

Ask again with the specifics and you will get a better answer than this one.

The figures, for anyone assembling their own picture. Practical: whatever you change, write down the date and the reason. In three months the reason is what you will have forgotten, and the reason is what makes the record worth having.

A narrower follow-up, since the general answer is now clear:

How long did you give it before you decided it was working?

Old thread, but it comes up first when you search for this, so it is worth updating. If you are comparing against somebody else’s result, check that you are comparing the same measurement taken the same way. Most of the apparent contradictions in these threads dissolve at that step.

True, and it depends on a baseline nobody has stated. Without knowing where someone started, the same number can be an excellent result or a disappointing one.
