In fact, there is a formula to calculate a person's daily protein. Nutritionist Dennis said: The protein mass that a person needs to supplement every day is at least one kilogram 1 g-1.5 g, which is the most standard. Teenagers, athletes, pregnant women and other people with special needs should reach 2 to 3 grams, and normal people need about 70 to 150 grams on average, which is equivalent to 0/-1.5 times per kilogram of body weight. By the way, the protein of an egg is about 5-7 grams.
