Adding the numbers, since they settle part of this. A quick sanity check on any figure quoted here: is it mean or median, is it intention-to-treat or completers, and what was the comparator. Three questions, and they resolve most disagreements in these threads.

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

Whether the RDA is the wrong reference entirely during rapid weight loss, and what the actual target should be?

Adding the part of the answer the thread has not reached. Read four things before the headline number. The population, because trial populations are selected and supported in ways that real cohorts are not. The comparator, because "better than placebo" and "better than the current standard" are different claims and get reported identically. The primary endpoint as pre-registered, because a secondary endpoint promoted after the fact is a hypothesis rather than a finding. And the completion rate, because a large effect in the half of participants who finished is a different result from a large effect in everybody enrolled.

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

Reporting back.

Front-loading was the answer. Same total intake, same drug, but two thirds of the protein before midday and I am hitting the target most days now.

Agreed on the target, with the caveat that reference weight and current weight are different numbers. Using current weight at the start of a large loss produces a target that is both unachievable and unnecessary.
