Abstract

A method for providing personalized recommendations to an individual, relating to monitoring his or her weight, comprising the steps of /a/ obtaining a plurality of prior weighings for the individual concerned, each weighing giving the total weight and the body fat percentage, /b/ deriving a characteristic curve (S1) for the individual by associating at least the total weight and the fat body mass, /c/ obtaining a target total weight (P2) for the user to achieve by the end of a target period, and therefore a target total weight change, /d/ deducing a target number of calories to burn, corresponding to target changes in the fat body mass and lean body mass deduced from the total weight change, /e/ providing the user with personalized instructions on exercise and/or diet.

Claims

1. A method for providing personalized recommendations to a user, relating to monitoring his or her weight, comprising the steps, executed in the following order, of:

/a/ obtaining, by means of an electronic scale, configured to measure the total weight and the body fat percentage of the user and to send the data to a remote unit by means of a wireless communication interface, a plurality of prior weighings of the user, each weighing giving the total weight and the body fat percentage,

/b/ deriving from the prior weighings, by means of the remote unit capable of performing calculations, configured to collect and process the collected data originating from the electronic scale, a characteristic curve specific for the user concerned by associating at least two of the following three quantities;

total weight, fat body mass, and lean body mass, over at least one total weight range,

/c/ obtaining, by means of the remote unit, a target total weight for the user to be achieved by the end of a target period, and therefore a target total weight change relative to the latest known total weight reading,

/d/ deducing, by means of the remote unit, from steps /b/ and /c/ a target number of calories to burn, corresponding to target changes in the fat body mass and lean body mass deduced from said total weight change by means of the characteristic curve specific for the user concerned,

/e/ providing, by means of a personal device connected to the remote unit, the user with exercise and/or diet instructions based on said target number of calories to burn,

whereby the user can receive, on the personal device, personalized recommendations for achieving the target weight.

2. The method according to claim 1, wherein step /a/ further comprises

/a1/ determining a current trend concerning the total weight of the user, by means of the most recent weighings,

and wherein step /d/ further comprises

/d1/ deducing, from the target total weight change, the change expected at the end of the target period, due to the current trend, the target number of calories to burn then being a relative target number of calories, such that the instructions given to the user are instructions on changing relative to recent habits rather than absolute instructions.

3. The method according to claim 1, wherein additional parameters including gender, age, and height of the user are also used in converting in step /e/ the target number of calories to burn into exercise duration for the user concerned.

4. The method according to claim 1, wherein the instructions are provided in the form of a number of steps to be taken.

5. The method according to claim 4, wherein, in step /e/, the instructions of a number of steps to be taken are added to an average daily number of steps taken in the past.

6. The method according to claim 1, wherein the characteristic curve (S1) is approximated by a straight line within a habitual weight range of the user.

7. The method according to claim 1, wherein the remote unit is a data server.

8. The method according to claim 1, wherein the remote unit is a smart mobile device.

9. The method according to claim 8, wherein the remote unit is combined with the personal device, the personal device being a smartphone, whereby the method is performed by a system comprising only the electronic scale and the personal device.

10. The method according to claim 8, wherein the remote unit is combined with the personal device, the personal device being a tablet, whereby the system comprises only the electronic scale and the personal device.

11. The method according to claim 1, wherein the personal device is a personal activity monitor and the instructions are displayed on it as a number of steps to be taken.

12. The method according to claim 1, wherein the personal device consists of the electronic scale itself.
