It is proposed to modify a digital coaching advice depending on trends of a physiological observable (e.g., weight, Body Mass Index, etc.). A digital coach varies the wording of his/her advice depending on the risk categorization. It is proposed to analyze physiological measurements for deviation from the mean and rate of change and to translate these basic statistics into a concept of urgency/risk to structurally vary the wording or appearance of a digital coach. Thus, a digital coach as proposed herein may look, act and talk differently depending on the urgency/risk of the users. Coaches may vary in language and appearance from gentle, via hard-but-fair, to “drill sergeant”. ## Claims ### Claim 1 A system for providing a health advice to a subject, the system comprising: a health level determining unit that is configured to determine a health level of the subject for a first time, wherein the health level is based on a comparison of a physiological observable of the subject at the first time to a target physiological observable of the subject; a health advice providing unit that is configured to provide a health advice based on the physiological observable of the subject at the first time and on a rate of change of the physiological observable of the subject over time; and an urgency assigning unit that is configured to assign a degree of urgency to the health advice based on the health level of the subject at the first time and on a rate of change of the physiological observable of the subject over time. ### Claim 2 (depends on 1) The system of claim 1, wherein the system further comprises a user interface, wherein the system is configured provide an appearance of the user interface based on the degree of urgency. ### Claim 3 (depends on 1) The system of claim 1, wherein the system is configured to provide a feedback to the user based on the assigned degree of urgency, wherein the feedback to the user is at least one of a visual feedback, an auditory feedback, a haptic feedback, and/or an olfactory feedback. ### Claim 4 (depends on 3) The system of claim 3, wherein the at least one of a visual feedback, an auditory feedback, a haptic feedback, and/or an olfactory feedback based on the assigned degree of urgency are selected from a memory unit. ### Claim 5 (depends on 1) The system of claim 1, wherein the system further comprises a physiological observable providing unit that is configured to provide the physiological observable of the subject at the first time. ### Claim 6 (depends on 5) The system of claim 5, wherein the physiological observable providing unit comprises an input unit that is configured to receive the physiological observable of the subject at the first time; and/or wherein the physiological observable providing unit comprises a sensor that is configured to measure the physiological observable of the subject at the first time. ### Claim 7 (depends on 1) The system of claim 1, wherein the system further comprises a feedback urgency database that is configured to store a table defining the degree of urgency depending on the health level of the subject at a given time and on the rate of change of the physiological observable of the subject over time. ### Claim 8 (depends on 1) The system of claim 1, wherein the target physiological observable of the subject is dependent on time. ### Claim 9 (depends on 1) The system of claim 1, wherein the system further comprises an effectiveness analyzing unit that is configured to correlate the assigned degree of urgency over time with the determined health level over time, wherein the effectiveness analyzing unit is further configured to provide an effectiveness rating based on the correlation. ### Claim 10 (depends on 1) The system of claim 1, wherein the system further comprises a display unit that is configured to display the health advice taking into account the assigned degree of urgency. ### Claim 11 (depends on 1) The system of claim 1, wherein the system further comprises a speaker unit that is configured to provide the health advice as an acoustic sound taking into account the assigned degree of urgency. ### Claim 12 A device for providing a health advice to a subject, the device comprising: a health advice providing unit that is configured to provide a health advice based on a physiological observable of the subject at a first time and on a rate of change of the physiological observable of the subject over time; and a degree of urgency providing unit that is configured to provide a degree of urgency corresponding to the health advice based on the health level of the subject at the first time and on a rate of change of the physiological observable of the subject over time; and a user interface that is configured to provide the health advice to the subject, wherein the user interface is configured to vary an appearance of the health advice depending on the degree of urgency. ### Claim 13 (depends on 12) The device of claim 12, wherein the user interface is configured to provide the health advice to the subject by means of at least one of a visual feedback, an auditory feedback, a haptic feedback, and/or an olfactory feedback; wherein the user interface is configured to vary the at least one of a visual feedback, an auditory feedback, a haptic feedback, and/or an olfactory feedback depending on the degree of urgency. ### Claim 14 A method for providing a health advice to a subject, the method comprising the steps of: determining a health level of the subject for a first time, wherein the health level is based on a comparison of a physiological observable of the subject at the first time to a target physiological observable of the subject; providing a health advice based on the physiological observable of the subject at the first time and on a rate of change of the physiological observable of the subject over time; and assigning a degree of urgency to the health advice based on the health level of the subject at the first time and on a rate of change of the physiological observable of the subject over time. ### Claim 15 (depends on 14) A computer program for providing a health advice to a subject, the computer program comprising program code means for causing the system to carry out the steps of the method for providing a health advice to a subject as defined in claim 14, when the computer program is run on a computer controlling the system for providing a health advice to a subject.
