Properties of gastric contents for optimal stuffing enjoyment

In your experiences, what foods or mix of foods create the best and worst stuffed feelings?
I've been thinking it has to do with more than a meal's nutritional content, mass, and volume, but also the viscosity of the gastric contents.
I theorize that the best mixture would be a smoothie like consistency that, while thick, can still be poured. Anything that turns solid or doughy in the stomach will probably produce more discomfort. Anything excessively liquid will produce a very sloshy feeling which can also be bad.
Let's gather the data and see where it leads.
