Body odor and food intolerances

Is it possible for foods to cause Body Odor ? I have constant Body Odor (it's really the worst thing ever because people can smell it from out side my house. ps my room directly faces toward the street) despite showering at least twice a day and using hibiclens. So bacteria isn't the problem.

I've just realized 2 months ago that i immediately smell worse after eating pork (i was trying to eat vegan that month). Then a month after that i got my food allergies & intolerances' test result. It showed that i'm intolerant to basically all meat, grains, nuts, seeds, some fruits and fishes, candida, yeast, even black pepper. I tried to avoid these foods, but it seems like the Body Odor still won't go away.

Does anyone have any advise for me to reduce the body odor?
