Abstract
An energy consumption estimator includes a body motion sensor, a first calculation unit, an acquisition unit, and a second calculation unit. The body motion sensor detects body motion by a user. Based on the body motion detected by the body motion sensor, the first calculation unit calculates the user's total energy consumption. The acquisition unit acquires the user's energy consumption derived from fats and lipids. Based on the energy consumption derived from fats and lipids and on the total energy consumption, the second calculation unit calculates the user's total energy derived from carbohydrates.
Claims10
An energy consumption estimator comprising:
- a total energy consumption acquisition circuitry configured to acquire a total energy consumption for a user;
- a fat energy consumption acquisition circuitry configured to acquire an energy consumption derived from fats for the user;
- a carbohydrate energy calculation circuitry configured to calculate an energy consumption derived from carbohydrates for the user based on the total energy consumption acquired by the total energy consumption acquisition circuitry and the energy consumption derived from fats acquired by the fat energy consumption acquisition circuitry;
- a comparison circuitry configured to compare a first energy consumption acquired by the fat energy consumption acquisition circuitry before a most recent meal with a second energy consumption newly acquired by the fat energy consumption acquisition circuitry;
- and
- wherein when the second energy consumption is greater than the first energy consumption, the comparison circuitry determines the energy consumption derived from carbohydrates calculated by the carbohydrate energy calculation circuitry as carbohydrate energy in the most recent meal, and
- the fat energy consumption acquisition circuitry includes an acetone detection circuitry configured to detect an amount of acetone released by the user and a fat energy consumption calculation circuitry configured to calculate the energy consumption derived from fats for the user based on the amount of acetone detected by the acetone detection circuitry.
