Protein: What Actually Matters

The protein conversation has an unusual amount of detail attached to a fairly simple underlying picture. There is a great deal of discussion about anabolic windows, per-meal absorption ceilings, and the precise superiority of one protein source over another. Most of it is real but small.

The number that does the work is total daily intake. Somewhere between 1.6 and 2.2 grams per kilogram of bodyweight, distributed with reasonable evenness across the day, captures nearly all of the available benefit for nearly everyone training with intent.

The thirty-minute post-training window turned out to be much wider than originally believed — closer to several hours, and largely irrelevant if you have eaten protein earlier in the day. Distribution matters somewhat: three or four meaningful protein feedings beat one enormous one. But this is a refinement, not a foundation.

Source matters mostly through leucine content and digestibility. Animal sources hit the leucine threshold in smaller portions. Plant sources get there too, in larger portions or in combination. Neither fact should change what you eat if you are already hitting the daily number.

Which brings us to the honest position on powder: it is food that is convenient. It does not do anything a chicken breast does not do. Its entire value is that it makes hitting the daily number easier on days when cooking is not going to happen. That is a real value, and it is the only one being claimed.

If you are not consistently hitting the daily number, no amount of optimising the rest will matter. If you are, most of the remaining variables are worth a percent or two.
