I read alot about sleevers low carbing it on this site. I was an atkins buff back about 5 years and I knew all about ketosis, I tested my urine with strips and all. I lost a lot of weight, but gained it back once I got a tatse of carb again. I deciced back then low carb is not right for me! With my sleeve I am eating well balanced healthy carbs. So I was suprised to hear that I had ketones in my urine after a u/a I had for a UTI. My doctor says I am still burning fat and this can happen. Hmmmmm..... has this happended to anyone else? I am not diabetic or even pre-diabetic.

It's quite common to spill ketones when eating very low calorie, too. It's just a sign that you are burning fat.
