Cause its the substance Human beings have been using for thousands of years now to fuel their bodies. A very Small tiny fraction of society thinks human beings can go without carbs. If its so great how come were not all on this carb-free diet? How come its not being taught in middle school and high school nutrition classes? Cause its another fad that will die just like any of these other BS diets out there. Consume less calories ..... its not rocket science. Millions of ppl have lost millions of lbs on regular diets where carbs are a part of their daily intake as it should be AND they dont put themselves at risk for Diabetes due to their low Testosterone levels..... Thats why!
