ketone urine test strips to measure fat burning
The latest fad in dieting is to use ketone urine test strips to measure fat burning.
The paper strips (THINZ MetaboSTIX, Lipostix, Ketostix) are popular with people on Atkins and other low-carb diets. They measure ketones in the urine...to show that the body is burning fat.
There are problems with this concept.
