                                While our bodies can't directly digest fiber, it is not calorie-free, with a complex fermentation process giving it a variable energy value. For most nutrition and weight management purposes, the caloric contribution from fiber is considered negligible, but understanding the details can be beneficial for specific dietary plans like keto.
