For what it is worth, I was vegan and then raw vegan for about 5 years. Granted, I did not smell of rotten meat but 1. I didn't lose any weight (main reason I tried it) and 2. I still smelled of FBO. I went fruitarian and that actually made my stench worse. I think I have fructose malabsorbtion and the fruit and veggies kicked the fbo up. FODMAPs I have been on for about a year and if I eat too much animal fat the fbo is bad as well, but I have cut the smell down considerably with this diet. Keep a food journal and see what works best for your body. Good luck.
