This confused me. What if you are on a low carb diet or what if you don't eat many carbs to begin with??

The word carb is not used in the correct context here. They are talking about burning glucogyn, which is a sugar that your body makes and stores in the liver. Your body makes glucogyn one of two ways, converting carbs that have been eaten, or converting stored fat to glucogyn. When you are low carbing for an extended period of time, like in keto or tkd, your body willingly uses stored fat for energy. It can only do this efficiently for so long before a refeed is needed.
