Thanks, everyone for your answers, and for your warnings about potential stomach problems.
Perhaps I should elaborate. For the past 2 years or so, I had found a good combination of diet and exercise that gave me weight stability (neither up nor down). But for the past 2–3 months I’ve found that I needed to have a midnight snack on most nights of the week. If I don’t have the midnight snacks, my weight actually goes down about 1 pound a week. I thought that maybe this was due to developing a bad habit of not chewing my food thoroughly. I thought that maybe if the food particles were larger, they might not get digested and absorbed and would just pass through. Thus I might not get the nutrients I need.
But as a side effect, I thought that this could be a weight loss idea, if someone were to do this on purpose.
