You need to see a doctor. Thinking about it, you have also mentioned hard stools. If you have a kidney or urinary tract infection, that could be you be causing both the burning wee and the hard stools. Drink a glass of water every hour or two, or sip some every few mins, to help while you wait to get medical advice.
what makes you think it has anything to do with the quantity of meat you eat? and can you eat dairy? nuts? many vegatarians and vegans do Low carbing. I think there is a part of the forum dedicated to their lifestyle. why is Tofu bad? in what way?
Pardon me if I am wrong, but it sounds like mild dehydration. During dehydration the urine becomes concentrated with salts, urea and ammonia, which would explain the burning sensation. But, better safe than sorry, get a check up and put your mind at ease.
I'm not saying it does, I'm saying that meat is generally a more acidic food and that a relatively higher (certainly in my case) protein load is thus harder on the kidneys.
I drink a lot of water. I certainly don't feel dehydrated.
