Would having fewer villi in you small intestine make underweight or overweight?

Having fewer villi in the small intestine would likely lead to underweight.

The villi are small, finger-like projections that line the small intestine and help to absorb nutrients from food. They are covered in microvilli, which are even smaller projections that further increase the surface area for absorption. If there are fewer villi, then there is less surface area for absorption, and the body is less able to take in nutrients from food. This can lead to malnutrition and underweight.

In contrast, having more villi would allow the body to absorb more nutrients from food, which could lead to overweight or obesity. However, it is important to note that many other factors, such as diet and exercise, also play a role in weight management.
