eazy info....getting shredded
 

Unfortunately one of the hardest things about getting as shredded as possible is the lowering of your carb intake. Your brain looks for glucose, which is produced when your carb sources get metabolized, as its primary source of energy.
When that energy isn’t there in surplus, you start to feel tired and lethargic.
This is a byproduct of getting shredded so suck it up. Low carb intake is a strategy that is difficult but effective.
