I know that there's been a question posted earlier about Smelly Urine, but I feel my situation is different.
In the past couple weeks, my urine has developed a rather strong odor, akin to a kind of mustiness (if I ever wanted to mark territory, I'd be doing it with this stuff). Once it a while I also get a smell similar to hydrolyzed proteins (think strong salty chicken broth, or yeast extract/Luria Broth for those in the biological sciences). My urine is also almost always colored (yellow with a hint of brown), although I'm not really that thirsty, and drinking a lot of water just yields a lot of urine with a fainter smell and color.
My questions are:
Haven't changed anything that correlated with the odoriferous urine, as it started two or more weeks back. In general, I eat low carb, 60 or so carbs per day, but I eat 100g two meals prior to weight training. I also eat fruit probably twice a week. Typical meals consist of 300g ground beef/pork along with 50g butter and some sauerkraut, although I eat spinach with some, and make stews with chicken/turkey occasionally. I've pretty much ate this way for the past month or two.
Recently I'm adding in carrots, and switching from sauerkraut to something else, like fresh cabbage or more spinach.
In regards to ketosis, I've been in deeper keto before, and haven't had this scent of urine before. It doesn't really smell acetone-y, or like any ketone bodies that I'm familiar with. Also, the past couple days I've been eating four to six carrots a day, along with fruit on Thursday, and this morning I ate approximately 20g of sugar in a chocolate bar, which hasn't affected to odor. This makes me think that it's not necessarily affected by my state of keto, although I'll test with ketostix later - I still have them from my VLC/keto days.
Turns out I switched brands from conventional to organic sauerkraut. I stopped eating the organic stuff and the scent went away.
Have you also included any asparagus by any chance? The chemicals released in urine when eating asparagus will give a very strong odor.
Cabbage tends to have similar compounds, albeit nowhere near as strong.
However, what it sounds like to me, is a high acid ketosis. When I first decided to go very, very low carb, after 2 weeks or so I had very acidic smelling BO and Urine. It only went away when I took out the high protein/low fat foods and started eating considerably more fat. If you are getting too much protein (over 2gm/lb LBM) then there is a good chance that is contributing as well.
Finally, do you take any medications? Oral steroids specifically can do what you are describing.
I would agree that you are likely in a high state of ketosis. You are eating very low carbs, so if you are working to shred fat, that is great. However, since your urine color is very yellow, you should increase your water intake. This will help your kidneys flush out more toxins and fat. Drink enough until your urine is clear again.
Do you drink a, lot of milk? L- tryptophan can add a strong turkey fat like smell to your urine. This essential amino acid is present in small quantities whenever protein is broken down... Your body can not make it, so it comes from foods like milk, evgs, and poultry, whose proteins have a much higher percentage of it than we need to synthesize our protein. The excess goes out in the urine, and hence the smell... It is harmless.
