I'm sorry but you really don't know what you are talking about. I think you have accumulated a lot of repeated information from blogs and shoddy websites instead of from science.

This is the only reference I see in pubmed for calories and black pepper and it says black pepper raises the resting metabolic rate, nothing about absorption. And it shows black pepper reducing obesity which would be the opposite of what you are describing.
