eat same foods .. smell same .. unable to smell self as well as others.   the foods one eats can affect body odor. eating lots of processed foods and questionable meats (such as eating pork predominantly) can cause body odors. smoking weed..people that smoke lots of weed tend to smell awful imho. living in old houses with poor ventilation can affect the smell of clothing esp. if high levels of mold or sewer gases are present.
