As far as I know, this is only true for soluble fiber, as it agglomerates around food in the stomach.

What's interesting, though, is that soluble fiber also gets converted into short-chain fatty acids by bacteria in the large intestine. Soluble fiber "has calories" (although technically it's a "precursor"), and, depending on the bacteria in your LE, it might be more per gram than carbs and protein. They don't show up on many nutrition labels (especially in Canada) because this is a more recent development and labeling laws haven't caught up. For the most part, it isn't even possible to predict the calories from fiber since the bacterial profile may vary widely between people.

"For individuals trying to lose weight, higher fiber diets will not only have positive effects on fullness and the rest but will result in less total calories being absorbed from the diet. "

Do you count the fiber carbs as carbs while dieting or do you count only NET carbs?

"Put more concretely, an increase in dietary fiber from 18 to 36 grams per day might reduce total caloric absorption by 100 calories per day."
Is this the where "vegetables has negative calories" comes from?

Net Carbs.

Can someone please resolve me from contradictory information about Psylium husks. Is it soluble or insoluble fiber? One article says it is, other says it isn't and so on. It's not a question of life and death but I just want to be sure.

My sources list psyllium as a soluble fiber. Maybe it has both?

Both.

Thanks. My head stopped hurting now

Is this really that big a deal though?

If you consume 200g/day, 5% would be 10g of protein lost, at the high end.

It seems like the benefits to the extra fiber might outweigh this, and even so getting 10 extra grams in a 24hr period sounds doable.
