For most people 125 g is already a solid daily amount. Standard guidance is around 1 g per kg body weight, or 1.5 g per kg of ideal weight while on GLP drugs, so unless someone is quite tall and muscular this level is adequate. Evidence for needing much more is not strong. A big morning serving might mean some of it gets used for energy instead of tissue, yet the same large dose also curbs hunger effectively for many hours afterward.
Reta has cut my appetite so much that the only reliable way to get protein is a morning glass of milk with three scoops of powder for roughly 75 g, then 50 g from chicken and fish later, reaching 125 g total. Skip the morning shake and I drop to just 50 g for the whole day. It is not the best approach but still better than missing the target entirely.
