So, if your main interest is maintaining and/or building muscle, then it can be beneficial to ingest protein early in the day. You would still want to obey this what we're calling a kind of foundational rule of no not eating any food for the first hour post waking. And the cut off for when you would want to eat protein would be sometime before 10:00 a.m. However, it's very interesting that it doesn't matter when the resistance training, the loadbearing exercise occurs in the 24-hour cycle. So whether or not, in other words, people are training early in the day or they're training late in the day, it still appears that ingesting protein early in the day favors hypertrophy.
