Diet and activity-monitoring device

A portable device for recording diet and activity data for a subject, the device comprising:

• a housing configured to be carried by the subject;
• a display for displaying information to the subject;
• a body activity monitor operable to monitor the body activity of the subject;
• an input operable by the subject to note when food consumption occurs;
• a timer operable to output a time indicative signal;
• a processor in communication with the input and operable to receive the time indicative signal, the processor further operable to determine and store the times when the input is operated by the subject;
• a microphone;
• and
• a microphone control, the microphone control operable to receive and store an audio signal from the microphone whereby the subject can record an audio notation.

A method of creating a consumption log for a subject comprising:

• providing a portable device having a consumption notation control operable by the subject to record the times that the subject consumes food;
• operating the consumption notation control each time the subject consumes food to record the consumption time;
• providing a computing device operable to display consumption choices for each time the consumption notation control is operated, and to receive the recorded consumption times from the portable device;
• transferring the recorded times to the computing device;
• displaying the recorded times to the subject;
• and
• recording foods consumed for each of the recorded times.

A device for monitoring the diet and activity of a subject comprising:

• a processor having a memory and a communications transceiver;
• a timer operable to transmit a time indicative signal to said processor;
• a body activity monitor for monitoring the body activity of the subject, the body activity monitor operable to transmit a signal to said processor indicative of the body activity of the subject;
• a consumption notation control operable by the subject to indicate the subject is consuming food and is operable to transmit a food consumption signal to said processor;
• an acitivity calculator within said processor that calculates a body activity level for the subject using the body activity signal;
• and
• a consumption calculator within said processor that receives the consumption notation control signal and the time indicative signal, and uses the consumption notation control signal and time indicative signal to determine and store in the memory a duration of time the subject consumes food or engages in an activity, wherein the communications transceiver transmits the duration of time the subject consumes food or engages in an activity to a remote computing device.
