The RDA is the wrong reference and it is worth understanding why.

I will push back on the powder-first advice. It works and it also trains people out of eating food, and when the drug stops the habits are what remain. Getting protein from meals is slower and holds up better afterwards.

Adding the numbers, since they settle part of this. 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.

Adding the part of the answer the thread has not reached. It helps to say which part of this you are uncertain about. A precise question gets a precise answer; a general one gets everybody’s favourite anecdote.

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

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

Reporting back.

Update: two thirds of the target before midday. Same total, same appetite, and I am hitting it most days now.
