Abstract

A wrist-mounted device for assisting a person to maintain a calorie balance goal comprises a processor; a display; a product identifier input mechanism; an activity level input receiving an activity level signal correlated with the physical activity level of the person; a resting metabolic rate input mechanism; a database correlating product identifiers with nutritional data; and a calorie management algorithm, adapted to calculate a calorie balance from the calorie values of foods consumed, the resting metabolic rate, and the activity level signal, and to present the calorie balance to the person on the display. Embodiments of the wirst-mounted device are also useful in blood glucose control.

Claims

a resting metabolic. rate input mechanism, wherein the person can enter a resting metabolic rate;

a database, residing in the memory, correlating the product identifiers with calorie values; and

a calorie management algorithm, adapted to calculate a calorie balance from the calorie values correlated with foods consumed, the resting metabolic rate, and the activity signal, and to present the calorie balance on the display.

2. The wrist-mounted device of claim 1, wherein the activity level input mechanism is a wireless transceiver adapted to receive an activity signal from a body-mounted activity monitor.

3. The wrist-mounted device of claim 1, wherein the product identifier input mechanism comprises a bar code scanner.

4. The wrist-mounted device of claim 1, wherein the resting metabolic rate input mechanism comprises a communications link with an indirect calorimeter.

5. The wrist-mounted device of claim 1, further comprising a glucose sensor adapted to provide a glucose signal correlated with a blood glucose level of the person, whereby the blood glucose level can be presented to the person on the display.

6. The wrist-mounted device of claim 1, further comprising an alert, whereby the person receives an alert when the blood glucose level of the person approaches a limit of a medically acceptable range.

7. A wrist-mounted device for assisting a person maintain a blood glucose level within a safe range, the device comprising:

a processor;

a memory;

a display;

a glucose sensor, providing a glucose signal correlated with a blood glucose level of the person;

a food identifier input, receiving food identifiers correlated with food items consumed by the person;

a software application program, executable by the processor, receiving the glucose signal, further receiving food identifiers, and adapted to calculate a future level of the blood glucose level for the person.

8. The wrist-mounted device of claim 7, wherein the food identifier input is a barcode scanner.

9. The wrist-mounted device of claim 7, wherein the food identifier input is a wireless transceiver.

10. The wrist-mounted device of claim 7, wherein the food identifier input comprises one or more buttons.

11. A system for calorie balance and blood glucose management, the system comprising:

a body-mounted device, having a processor, memory, clock, a display, and an input mechanism for food identifiers correlated with consumables consumed;

a metabolic rate meter in communication with the body-mounted device;

a glucose meter in communication with the body-mounted device, providing a glucose signal correlated with the blood glucose level of the person; and

an algorithm, executable on the processor, adapted to receive a metabolic rate measurement from the metabolic rate meter, a glucose signal from the glucose meter, and food identifiers from the input mechanism, and further adapted to display a current calorie balance for the person, and the blood glucose level of the person.

12. The system of claim 11, further comprising an activity monitor in communication with the body-mounted device.

13. The system of claim 11, further comprising an audio alert, wherein the person receives a warning if the blood glucose level approaches the limit of a safe range.
