It may seem putrid to you, but I would suggest urine therapy as in drinking your own urine.   You can go to the UT support forum for suggestions but I've been doing this now for about eight years and here's what I suggest.  Start with just a couple of tablespoons a day, perhaps for a week.  Then begin working your way up to at least a cup a day which will take two or more weeks.  You may have some diarrhea in the process and if you do, cut back a little but that will eventually go away as your body adjusts.  Your urine may taste horrible in the beginning, but it will improve in taste (not your head) as you continue.  That's what happened to me and yes I do go off of UT once in and while and when I restart the urine is strong but improves every time within a week.

Here's a testamonial from Cure Zone on UT improving body oder:

"My body odor still persisted until I started urine therapy. I know for a fact that the other things I've done helped cleanse my body and made it easy for urine therapy to finish the cleansing. I wouldn't recommend anyone to just rely on urine therapy and not the other ways of cleansing. Yet I have to say that it was urine therapy that improved my odor so much."

Try drinking cranberry juice or have your kidneys checked.     http://symptoms.wrongdiagnosis.com/cosymptoms/body-odor/urine-odor.htm
 

The first thing I would do is the master cleanse! You wouldn't believe how cleaned up you can get by doing this. I used to have not so nice body odour after exercise, but not anymore! I'm not talking about a long cleanse, just do a 10-12 day cleanse. It is difficult, but definitely do-able!  It's a pretty simple cleanse. Buy the darkest maple syrup you can buy (unprocessed organic), 2 bags of organic if possible lemons, fresh cayenne pepper, and pure spring water for mixing. 

I usually mix 3 - 10oz cups at a time. For each 10oz. cup, you add 2 tbsp of the maple syrup, and 2 tbsp of fresh squeezed lemon juice ( 1/2 a lemon ), and a pinch of cayenne pepper (1/10th tsp) or as much as you can stand as it's very cleansing, mix that up, and gulp it down. You drink 6-10 glasses a day, and NOTHING ELSE, except maybe peppermint tea from time to time, and every night before bed, drink a laxative (senna) tea. I just bought senna leaves, but they have senna prepared teas you can buy.

The morning is the toughest. Drinking 1L (quart) of salt water. Add between 1-2 tsp of non-iodized sea salt to 1L of spring water, and chug, I modified it to put that amount of salt into about a 10oz. glass, chugged that quickly, and then chased it with the remaining water, this worked good too.

Stay near a bathroom after this, for at least 1 hour, trust me! Adjust the salt as needed, it should make you have to run to the bathroom within 10-15 mins of dowing the salt water, this is what you want! 

That is pretty much all there is to it. Whatever you do, don't eat anything else. Do not take any supplements or pills of any kind, as your system will be very sensitive while cleansing.

After the cleanse, start slow to get back onto food. The first day, maybe just some orange juice in the AM and then in the pm, just some soup (broth) with boiled vegetables at most. You can still have a cup or two of the lemonaide if you like. Second day, progress slowly, don't eat anything to heavy (fruits, veggies, soup)..by the 3rd day you should be fine to eat almost anything, but I would still not eat too heavy.

After the cleanse I highly recommend taking spirulina and chlorella to repair your body fully. Read www.chlorellafactor.com/ you will be glad you did!

If you take this advice, I'm almost sure your problem will dissapear! Good luck!
