Using the calculator, you can calculate and estimate your body mass index (BMI) based on your height and weight. Age is additionally taken into account in this process. The calculated result is represented by a slider in the form of a colored panel, where the state of each color indicator corresponds to a certain TMI state. Based on the result, users are given recommendations for nutrition and exercise. This calculator aims to provide clear and practical guidance to the user, taking into account important aspects of personal health.
