carb calorie question

[AzBboy]

Hi everyone, I was reading somehwere that certain carbohydrates contain NO calories. Anyone know anything about this? I think it was something like subtract the fiber from the carb total or something or other. Can anyone offer some insight? Thanks in advance.

No calories?

Perhaps wood pulp?

even fiber has calories.
most ppl think fiber has no calories, but the fact is that each gram of soluble fiber contains 1.5 calories.

I think what you're referring to are so-called "negative calorie" foods. That is to say foods that take more calories to digest than they yield. I googled it for you:

I don't know why you're asking though, you could never really plan a healthy or even reasonable diet around such foods. Or at least not in any meaningful way for bodybuilding purposes.

Quite right about the soluble fibre. The insoluble stuff can be different, though methinks.
