I’m cutting right now, and thanks to protein being only 4kcals/gram, having a very high thermic value, and having a very high satiety value, I eat 250-350g of protein a day. Believe it or not, your body can render it into energy when it’s not being used to repair tissue.
Plus, protein is critical for the following operations unrelated to synthesis of new muscle tissue:
- Protein turnover of all body cells, including organ, connective, and adipose tissue.
- Essential for the production of enzymes, coenzymes, and hormones.
- Can be used as energy if fat/carb supplies are insufficient.
- Maintaining bodily nitrogen balance.
Not to mention, females stay in a state of puberty until about age 22 and males until the age of about 25, during which time they have a high requirement for protein since they’re still making relatively major bodily changes.
Not to mention, a high consumption of protein is critical during workouts. Cortisol, a catabolic hormone, is suppressed by protein consumption during high physical stress (i.e. lifting weights) while anabolic hormones (T, IGF-1, GH, insulin) are promoted.
And, like others have said, everyone’s body is different. One friend that I train just doesn’t respond without ridiculous amounts of protein. Why should I tell him to force himself down to a specific, arbitrary number if 450g of protein a day works well for him?
I think you need to lurk more, OP.
