The WHR calculator calculates the ratio of waist circumference to hip circumference.
Thanks to the Talia-Hips calculator, we will find out what type of obesity we have, what is the risk of hypertension, coronary diseases, stroke, atherosclerosis and diabetes, and we will learn the average standard WHR for our gender and age.

The caloric demand calculator will help you create the right diet. It will answer the question of what is our daily calorie requirement and how much daily do we need to consume carbohydrates, proteins and fats to gain weight or lose weight by a given weight within a certain period of time.
We have a choice of several of the most popular formulas for calculating the basal metabolic rate. As a result, we will also get a seven-day alternating caloric cycle, thanks to which, with long-term diets, we can "cheat" the body by consuming different caloric values a day while maintaining a weekly diet.

With this calculator you will calculate the average absolute deviation, or mean absolute deviation (MAD), of a data set is the average of the absolute deviations from a central point.
