Question

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

Explanation:

High - fiber foods absorb water and expand in the stomach, leading to a prolonged feeling of satiety. This reduces overall calorie intake as it curbs hunger pangs, which is beneficial for weight management. High - fiber foods do have calories, weight is not related to their weight - management benefit, and adding bulk to feces is more related to digestive health rather than directly to weight management.

Answer:

because they make you feel full longer
