weight loss side effect? body odor & nicotine smell?

i have begun losing fat recently and i have also noticed that my sweat smells different and much stronger, almost like a faint whiff of acetone. it's pretty bad but i also caulked it up to fat cells beginning to release accumulated fat soluble toxins into my sweat and blood stream. I don't have anything but anecdotal evidence to prove that this detox is occurring but it only stands to reason since fatty acids are excreted in apocrine sweat and if you are losing weight it makes sense that there would be more fat in that sweat along with any toxins that were in solution when stored in the fat.
