Well....2-9 pounds of you body weight is bacteria.(Actually, I've read elsewhere that it is much more than 2-9 pounds.)

"It appears that the average human bacterial load is approximately 2 to 9 pounds, depending upon which reference source is consulted. Below you'll find a variety of sources from which to choose."

"It appears that the average human bacterial load is approximately 2 to 9 pounds"

If you take anti-biotics for some infection, does that reduce the weight of bacteria, and your overall weight?
