What is a common consequence of insufficient fiber intake?

Insufficient fiber intake is primarily associated with constipation. Fiber is essential for normal bowel function as it adds bulk to the stool and helps to facilitate its passage through the digestive tract. When a diet lacks adequate fiber, the stool can become harder and more difficult to pass, leading to infrequent or painful bowel movements, commonly referred to as constipation.

In contrast, other options such as increased appetite and weight loss do not directly correlate with a lack of fiber. While fiber can actually promote feelings of fullness and help regulate appetite, insufficient intake does not guarantee increased appetite. Similarly, while some may experience temporary weight loss due to digestive issues stemming from low fiber, it is not a common or healthy consequence. Improved digestion is also not a consequence of low fiber; rather, sufficient fiber is critical for promoting healthy digestive processes.
