I have a debate going with my dad, he says I shouldnt use protein powders because it has chemicals and it will alter my metabolism. He said your trying to eat healthy and only eat natrual things, but you take shakes that are made unnatrualy.
This just made me laugh but I was wondering what protein shakes are acually made of. Things like whey and Metabolic Drive. Also what do I say to him to convince him hes wrong. Its not like he said I cant take him. I just want to win the arguement since I usually dont haha
