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.

Is the chosen weight loss plan adjusted to your needs and possibilities and will it bring the expected results?

The key to success in dietary plans is its proper selection. However, too often we choose plans that are not tailored to us, resulting in ineffectiveness and discouragement, and consequently the quick abandonment of the plan.

Use this test to find out also what factors a tailored diet plan should contain and training sessions. And it's best to apply this test to the already selected plan so as not to waste time on a wrong diet and training.
