Please help me clear my confusionů

Ok after reading I
realized that 162 pound(lbm) person would need either 27g of protein from whey
or 43g of protein from chicken to obtain maximal protein synthesis .

Whey 27 x 4 shakes= 108
43g x 4 meals a day= 172

based or 4
meals/shakes would 108g from whey be as effective as 172g from chicken? For a
163 pound person?

Also on Intermediate fasting diet are muscle build
during the fested period or only during fed period?
