So lets discuss this.
Why do so many people think this is possible? There's a guy at the gym that swears his low carb approach to dieting allows him to gain muscle and lose fat simultaneously. How is this possible? It seems to completely go against everything you are taught in nutrition and metabolism classes. Besides, most of your pro BB go through a bulk/cut cycle. Seems like the pros would take advantage of that if possible huh?
An increase in LBM requires a caloric surplus. A decrease in fat content requires a caloric deficit. How can these occur at the same time?
Lets keep things civil and only focus on "normal" individuals. I'm not talking about the severely overweight fatasses you see on biggest loser, nor the 110lb skinny guy on starting strength.
