Eating more may not necessarily lead to gain meat, but exercise plus protein will definitely lead to gain muscle, which is beyond doubt! I am 1.75, originally125kg, now145kg, hehe. I don't know if it's from thin to strong, but I'm obviously beautiful and dressed in style. I am very happy. I didn't expect such a change.
