To build a pound of muscle, the body needs between 10 and 14 additional grams of protein per day.
That’s not really that much. Some of these powders have 80 grams of protein per serving. You don’t need that. All your body is going to do is break it down for energy. And too much protein can be hard on your kidneys and your liver.
The maximum amount of protein that most adults can use per day is 2 grams per 1kg of body weight.
So if you wants to build muscle mass, and you weigh about 80 kg, the most protein you would need per day is 160 grams. That sounds like a lot, but one 4-ounce hamburger contains 30 grams of protein, 1 can of tuna has 40 grams, and a single ounce of cheddar cheese has 7 grams, i medium chicken breast|(skin not eaten )contains 50 g protien,30 grams of protein from 1 cup of boiled soybeans,other sources of protiens are :fish (salmon,tuna ,halibut), cheese ,nuts,milk yogurt ,eggs,..
