no. Fiber is technically a carb but bc of the structure of fiber humans are not able to digest it. If you can’t digest it you can’t absorb nutrients from it —> no calories. Because it can’t be digested it helps move stuff through your gut —> pooping and decreased risk of colon cancer. Net carbs is just total carbs - carbs that are fiber (because they aren’t digested).
Kinda. Fiber is a carbohydrate, but your body can’t fully digest a lot of it, so it doesn’t raise ur blood sugar which is why people say net carbs = total carbs − fiber. It’s not literally canceling out the carbs it’s just the carbs that come from fiber aren’t fully digested or metabolized.
