1. A computer-implemented method of assessing an insulin activity error and its effect on glucose levels, the method comprising the computer-implemented steps of:
- measuring an amount of a fat metabolism analyte in a biological fluid sample and an amount of a glucose metabolism analyte in the biological fluid sample,determining, using a computer, a real insulin activity level, wherein the real insulin activity level comprises a reciprocal conversion of the amount of the fat metabolism analyte in the biological fluid sample,comparing, using the computer, the real insulin activity level with a theoretical insulin activity level to calculate the insulin activity error; and
predicting, using the computer, a prospective glucose level using the amount of the glucose metabolism analyte in the biological fluid and the calculated insulin activity error,wherein a positive insulin activity error is predictive of a glucose level which is lower than that predicted by the theoretical insulin activity level, andwherein a negative insulin activity error is predictive of a glucose level which is higher than that predicted by the theoretical insulin activity level.

Abstract
A health-monitoring device assesses the health of a user based on levels of two analytes in a biological fluid. A first analyte that is utilized to assess a user'"'"'s health is a fat metabolism analyte, such as ketones, free fatty acids and glycerol, which is indicative of fat metabolism. A second analyte that is utilized is a glucose metabolism analyte, such as glucose. The levels of the two analytes may be used to assess insulin sensitivity, to detect both recent hypoglycemia and the cause of high glucose levels, and/or to guide therapeutic intervention.
