There's good data to support this approach. I have one such example that I witnessed.

Many years ago a unit of the British army reserve did an experiment on how to keep soldiers satisfied for longer between meals, while performing physical tasks. They prepared a basic meal of potato, carrots, peas and two rashers of bacon. Half the troops got this served, as cooked, on a plate. The other half had their food tipped into a blender, turned into a thick mush, and served in a bowl (this group had no complaints about loss of flavour or texture and said afterwards they quite liked the blended food mush).

The result: the blended food mush group reported feeling satisfied and "full" for a couple of hours longer than the unblended group, while performing all the same physical tasks.

Conclusion: it was the surface area principle. The blended food filled the stomach more thoroughly and suppressed feelings of hunger more effectively, because of this. The unblended food was present in the stomach in larger, more discrete chunks that had gaps around and between them, allowing the stomach fluids to flow and feelings of hunger to be stimulated.

Suggestion: if you want to stay sated for longer and not crave food as often, blend it into baby food mush and eat it out of a bowl! ;-)

I've always been unclear about the dividing line between 'soup' and 'stew'. I think the above may qualify as a stew because of the length of time it's cooked for, but I'm generally inclined to call thick, especially meaty, dishes a stew. But then you've also got goulash (I grew up on goulash thanks to some Cajun heritage).

Ah, a subject very close to my food loving heart. A bowl of hearty, nutrient-dense soup is just about the most satisfying experience I know. If you pair it with a glass of something ice cold like lemon water, you'll get up from the table feeling like you've just polished off a holiday feast. Sorry for those who can't relate.
