(g) a timer in the housing connected to the processor; and
, (h) a display on the housing, the display comprising an indicator and connected to the processor, wherein the processor is adapted to compute and display on the display a calculated net calorie intake value based upon;
data entered by a user through the user input regarding the number of calories consumed by the user during a period of time; and
, a number of calories determined by the processor from data obtained by the processor from the timer and the heart rate monitor to have been expended by the user in exercise during the period of time.

Abstract
Apparatus for tracking net consumption of calories by a user has an input to allow a user to enter the number of calories in food consumed by the user. The apparatus also includes a heart rate monitor and a timer. The heart rate monitor and timer. A processor in the apparatus can calculate the number of calories expended by the user in an exercise session from the duration of the exercise session, as measured by the timer, and the intensity of the exercise session as measured by the timer. The apparatus may be provided as a light weight wrist wearable instrument. The apparatus simplifies tracking the expenditure of calories in exercise and makes it possible to vary dietary constraints on calorie consumption in accordance with the amount of exercise in which the user has participated.

14. Wrist wearable apparatus for monitoring a net calorie intake of a user, the apparatus comprising:
-
(a) a housing;
(b) a strap on the housing for attaching the housing to a user'"'"'s wrist;
(c) a data store in the housing for holding net calorie intake information for a user;
(d) an input on the housing for receiving calorie intake information entered by a user;
(e) a heart rate monitor in the housing; and
,(f) a processor in the housing, the processor running software instructions which cause the processor to;

15. A method for comparing the net calorie intake of a person during a period of time with a user defined target net calorie consumption, the method comprising:
-
(a) providing apparatus having a user input, a heart rate monitor, a timer, a processor, a memory and a display;
(b) periodically entering via the user input first data representing a first number of calories in food consumed by the person and allowing the processor to automatically add the first number to a value in a memory location in the memory;
(c) for each of one or more exercise sessions;
timing the exercise session with the timer;
measuring a heart rate of the person with the heart rate monitor;
in the processor, in response to measuring the heart rate, computing a second number representing calories expended by the person in the exercise session and subtracting the second number from the value in the memory location; and
,(d) comparing the contents of the memory location to the target value stored in the memory and indicating on the display relative magnitudes of the net calorie intake and target net calorie consumption.

17. A method for weight control, the method comprising:
-
a) providing a portable wrist wearable apparatus capable of;
i) storing a target net calorie consumption value for a time period and a user'"'"'s weight;
ii) recording a number of calories in food consumed by a user;
iii) timing a user'"'"'s exercise sessions;
iv) monitoring a user'"'"'s heart rate during the exercise sessions;
v) automatically computing calories expended by the user in the exercise sessions using durations of the exercise sessions and the user'"'"'s heart rate and weight;
vi) calculating a net calorie intake number by the user; and
