Use eggs instead of protein powder
To build muscle, protein must be supplemented, but if exercise is not done properly, excessive protein supplementation will be excreted by the kidneys in large quantities, thereby increasing the burden on the kidneys.
Not only is it a waste of money, it also has no effect.
Using eggs instead of protein powder is a good way. A 70 kg person needs to supplement 10-15 egg proteins every day when building muscle.
Of course, there are many other alternative foods, see the attached picture for details.
