Yes absolutely, total lie!
I used to eat like crazy in the begin years i trained, ate tons of protein from several sources. lots of shakes and supps, also because flex magazine told me that was required!! flex can you read this, pieces of shit.
Now that i dont anymore. not even shakes. eating like a normal person does. having lost zero muscle and even gained more muscle and became more trimmed.
I also think that when you dont eat a lot of protein that your body tends to use it more proper as well. but again, its all fabricated lies in these mags, really.
