The Recommended Dietary Allowance (RDA) for carbohydrates is 130 grams per day. This is the number of carbohydrates required for an adult, in order to fuel his or her central nervous system (including the brain) and red blood cells. It is important to have full glycogen stores because when we participate in the anaerobic exercise, our bodies switch from burning fat to our quick-burning sources of glucose in order to maintain our energy and our blood sugar level, and continue fueling our brains and our red blood cell production.
The number of carbohydrates you will need, however, will often depend on your body type and how much exercise you do. If you count macros you will have a better sense of how many carbs you actually need to consume in a day. If you don't count macros this number may be more difficult to pinpoint, but 130 is a good one to start off with.
