my sweat smells like ammonia- good or bad?
i have noticed lately that about half way through my workout, my sweat has this overwhelming scent of ammonia. usually i just ignore it, but sometimes it almost makes me nauseous, and it makes my sinuses itch. i dont feel any 'weaker' once this starts happening, but i get a bit of a headache. this happens everytime i work out.
i eat a 'reduced-carb' diet, but include some starches like potatoes and rice once every other day, (i have a food intolerance to wheat and most other grains- i get hives- so bread, oats, etc is out of the question), no fruit, some nuts, fibrous veggies, lean protein.
I usually do cardio for an hour a day, using the elliptical machine, at a moderately intense pace (usually 20km/hour) folowed by 1/2 hour of light weights/ calisthetics.
i did a bit of research, and one website said the that presence of ammonia-smelling sweat means i have entered ketosis (i did a met. stick test to check and ketones were present) and that the ammonia smell is an indication i am burning fat for fuel. if this is the case, it seems like the ammonia smelling sweat is a good thing, right? should i time my 1 hour cardio session from the time i enter ketosis for maximum results? The same site suggested drinking more water, although i drink about 2 L during my session. also, is going into ketosis the only way to lose body-fat? should i be concerned?
any insight is greatly appreciated!
