The present disclosure discloses an electronic coaster for estimating amount of calories consumed by a user, through a beverage present in a beverage holder. The electronic coaster comprises at least one weight sensor to measure weight of a beverage holder comprising a beverage and a computing unit to receive the measured weight from the at least one weight sensor, determine weight of the beverage based on the received weight, identify beverage type and a predefined calorific value corresponding to the beverage type, determine change in weight from the weight of the beverage and estimate total amount of calories consumed by a user based on the change in weight and the predefined calorific value.

1. An electronic coaster, comprising: at least one weight sensor to:measure weight of a beverage holder comprising a beverage;at least one image sensor to:capture an image of beverage in the beverage holder; anda computing unit to:receive the measured weight from the at least one weight sensor;determine weight of the beverage based on the received weight;determine spectral signature of the beverage based on the image of the beverage; identify beverage type based on the spectral signature by comparing the determined spectral signature of the beverage with predefined spectral signature of plurality of beverages stored in a database;identify a predefined calorific value corresponding to the beverage type;determine change in weight from the weight of the beverage corresponding to the beverage type; andestimate total amount of calories consumed by a user based on the change in weight and the predefined calorific value corresponding to the beverage type. 2. The electronic coaster as claimed in claim 1, wherein for every instance of the change in weight from the weight of the beverage, the computing unit is configured to: receive a subsequent weight from the at least one weight sensor; and determine change in weight by calculating difference between the subsequent weight and weight measured prior to the subsequent weight to estimate the total amount of calories. 3. The electronic coaster as claimed in claim 2, wherein the total amount of calories is estimated when the subsequent weight is lesser than the weight measured prior to the subsequent weight. 4. The electronic coaster as claimed in claim 1 further comprising at least one imaging sensor to identify the beverage type. 5. The electronic coaster as claimed in claim 1, wherein the weight of the beverage is determined by subtracting weight of the beverage holder from the weight of the beverage holder comprising the beverage. 6. The electronic coaster as claimed in claim 1, wherein the predefined calorific value corresponding to the beverage type is stored in a database accessible by the electronic coaster. 7. The electronic coaster as claimed in claim 1 further comprising at least one biometric sensor to identify the user associated with the electronic coaster. 8. The electronic coaster as claimed in claim 1, further comprising a user interface to: display information to the user; andreceive one or more inputs from the user. 9. The electronic coaster as claimed in claim 1, wherein the computing unit is further configured to: compare the amount of calories consumed by the user with a predefined threshold value for calorie consumption; andnotify the user based on the comparison. 10. The electronic coaster as claimed in claim 9, wherein the threshold value for calorie consumption is personalized for the user. 11. A method for estimating calories consumed by a user through a beverage, placed on an electronic coaster, comprising: measuring, by at least one weight sensor of the electronic coaster, weight of a beverage holder comprising a beverage;receiving, by a computing unit of the electronic coaster, the measured weight from the at least one weight sensor;determining, by the computing unit, weight of the beverage based on the received weight;determining, by the computing unit, spectral signature of the beverage based on the image of the beverage;identifying, by the computing unit, beverage type based on the spectral signature by comparing the determined spectral signature of the beverage with predefined spectral signature of plurality of beverages stored in a database;identifying, by the computing unit, predefined calorific value corresponding to the beverage type;determining, by the computing unit, change in weight from the weight of the beverage corresponding to the beverage type; andestimating, by the computing unit, total amount of calories consumed by the user based on the change in weight and the predefined calorific value corresponding to the beverage type. 12. The method as claimed in claim 11, wherein for every instance of the change in weight from the weight of the beverage, the method comprises: receiving a subsequent weight from the at least one weight sensor;determining change in weight by calculating difference between the subsequent weight and weight measured prior to the subsequent weight to estimate the total amount of calories. 13. The method as claimed in claim 12, wherein the total amount of calories is estimated when the subsequent weight is lesser than the weight measured prior to the subsequent weight. 14. The method as claimed in claim 11 further comprising identifying the beverage type by at least one imaging sensor configured in the electronic coaster. 15. The method as claimed in claim 11, wherein the weight of the beverage is determined by subtracting weight of the beverage holder from the weight of the beverage holder comprising the beverage. 16. The method as claimed in claim 11, wherein the predefined calorific value corresponding to the beverage type is stored in a database accessible by the electronic coaster. 17. The method as claimed in claim 11 further comprising identifying the user associated with the electronic coaster, by at least one biometric sensor. 18. The method as claimed in claim 11, further comprising: displaying, by a user interface configured in the electronic coaster, information to the user; andreceiving by the user interface, one or more inputs from the user. 19. The method as claimed in claim 11, wherein the computing unit is further configured to: compare the amount of calories consumed by the user with a predefined threshold value for calorie consumption; andnotify the user based on the comparison. 20. The method as claimed in claim 19, wherein the threshold value for calorie consumption is personalized for the user.
