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.

The calculator will calculate how much water you should consume to supplement your daily requirement.

You can calculate step by step any system of linear equations, both homogeneous and inhomogeneous with any number of unknowns by the Cramer's method. As a result, in addition to the solution, you also get a complete analysis and presentation of calculations step by step.
