Question

why is consuming high - fiber foods good for weight management? because they make you feel full longer because they weigh less because they have no calories because they add bulk to feces

Explanation:

High - fiber foods are indigestible in the human small intestine. They absorb water and expand in the digestive tract, creating a feeling of satiety that lasts longer, reducing overall food intake which is beneficial for weight management. They do have calories and their weight is not relevant to weight management in this context. Adding bulk to feces is related to digestive health rather than direct weight management.

Answer:

because they make you feel full longer
