This is not only to support what others say, but to take protein according to your fitness intensity, your height and weight, and the fitness effect you want to achieve after fitness.
According to a person who weighs 160 kg, after amateur fitness, running and playing ball, 15-20g is enough.
If you are an amateur bodybuilder, you want 30-40 grams of muscle.
It takes 60-80 grams to go to professional bodybuilding.
So eat according to your personal situation. If you are just an ordinary sports enthusiast, you'd better not use protein powder. Eat more high-protein food, enough to supplement the protein needed by the body!
I am a professional bodybuilder. I hope my answer is helpful to you!
