Ammonia Stench

How many people notice a weird smelling “ammonia” type stench as they approach low lvls. of bodyfat?. I am not necessarily talking about in the urine, but just a general odor that the body gives off daily. Esp. noticeable at night even after a shower.? Obviously this is a sign that increased protein catabolism has commenced, but i guess to eliminate virtually all subcutaneous fat, you got to give some to get some (esp. without androgens)?.
