A word about the Ketostix.

They do measure the ketones on your urine, and ketones are a by-product of fat breakdown. But it does not differentiate between dietary fat and body fat breakdown. As we all know, most low-carb diets are really high-fat diets, so a positive stix is not very conclusive about ketosis.

But if you continue to use them, keep this in mind. As mentioned above, if it reads a high concentration on ketones, you are not drinking enough water. But on the other hand if you see any positive reading at all (even a slight pink), you are passing ketones and could theoreticaly be in ketosis. Never perform the test in the morning because it will almost always read positive. Anyone on any diet can read a positive after 8 hours of fasting (sleeping). Instead, take a reading just before dinner or before bed.
