There are so many possible causes of body odor that it's very difficult to determine whether the source of your problem is localized fungal or bacterial infections in the mouth, underarms, feet, groin, and/or gut, or whether you have a metabolic condition. It may very well be a combination of these.
Why don't you tell us a little of what part of your body your odor is coming from, what you have done to try to control it, obviously without success,, and what you think your odor smells like.
You might want to read some of the posts we have written on my blog http://mpdela.blogspot.com/. You might find that using the 'Search posts through Labels' function to help you get to the information that you think might pertain to you.
Keep in touch, and let us know more about you. Sorry I took so long to reply, but i've been out of town.
