What are the pros and cons of having the digestion be slower and over distance, as opposed to being quicker and over shorter distance with slightly less absorption?

You will not digest the best amount of nutrients if food moves more quickly; if it passes much slower, there is far too much water taken from the stool which makes it more difficult to pass, creating issues such as constipation and other problems, such as hemorrhoids.

Digestion be slower and over distance

Pros: Absorb more nutrients and less likely to get hungry. Cons: Constipation because the longer the absorption takes, the more water is leeched into bloodstream.

Quicker and over shorter distance with slightly less absorption

Pros: Can eat a lot without feeling full / gaining weight. Cons: If food travels to your duodenum so fast, your digestive tract produces more enzymes than usual. Fluid also flows into your small bowel from your blood stream. Experts believe that excess hormones and fluid movement in your small intestine cause early dumping syndrome symptoms.
