Hey! I have done fasting in the past, because I figured some of the foods and beverages were the cause. Good news: it did reduce the body odour and I lost a good amount of weight. Bad news: it didn\\\'t get rid of it altogether.  I think if the body odour is relative to food/medication it is the Eccrine glands. Sour, musty, pungent more ammonia scented odours are Apocrine.
