Abstract: The glycemic index is determined based on the results of blood glucose concentration measurements by evaluating time ?t from the beginning of food-related increase of blood glucose concentration until the peak of glucose concentration is reached, after which maximum increase ?Gmax of said glucose concentration is determined over the given period of time. Thereat, the glycemic index of food is defined as a ratio of maximum increase of blood glucose concentration ?Gmax versus maximum increase of said glucose concentration in case of pure glucose intake in the amount equal to carbohydrate content of the consumed food, which is proportional to the product of ?Gmax by ?t. The invention substantially simplifies the procedure for measuring the glycemic index of real food and facilitates the development of simple personal devices for monitoring carbohydrate metabolism.

Abstract: A method for measurements of parameters characterizing human motor activity provides registration of signals generated by load sensors mounted in shoe insoles, with each insole having at least two load sensors, one mounted near the heel, and the other near the toe of the foot. The specific type of motor activity is determined based on temporal correlation of load sensor signals from both insoles and values thereof. Person's weight, including additionally carried weight, is determined by summing up signal values from said load sensors, with the specific type of motor activity considered; thereafter, person's motor stress is determined based on specified type of motor activity and person's weight, including additionally carried weight. The method enables a real-time monitoring of motor stress of a person at different types of motor activity, e.g. running, walking at different pace, standing, with person's weight, including additionally carried weight, taken into consideration.

Abstract: Determining a state of water deficiency in a human body during daily life activities is done by measuring an impedance of a portion of the human body at a low frequency and at a high frequency. An amount of fluid in the body tissues in the volume under study is assessed based on the impedance at the high frequency. A current amount of extracellular fluid in the tissues in the volume is assessed based on the impedance at the low frequency. A reference value of the assessed amount of extracellular fluid in the tissues is preselected at the start of measurements. A correction value is determined based on the changes in blood amount in the volume at the current measurement time. A corrected assessment value is the determined. Using the corrected assessment value, the onset of water deficiency is determined.
