I asked about the exercising because this smell is common with weightlifters, runners, and people who work out.

Other than that, some people who smell like ammonia are infected with a bacteria called helicobacter, it grows in your stomach and intestines and causes ulcer symptoms characterized by belching, burping, a sour taste in your mouth and a burning pain that often become more severe when you are hungry and better when you eat.

Ask your doctor to do a blood test for helicobacter. If you are infected, you can be cured with a one week course of metronidazole, amoxacillin and omeperazole.

If your test comes out negative, you may need to eat less meat, fish, chicken and dairy products. When you take in more protein than your body can use immediately, your body strips ammonia from protein, and what doesn't come out in the urine will come out in the sweat, which would cause you to smell and taste it as well.
