How to calculate calories for weight loss?

I have been trying to lose weight for several months now, but the results are not pleasing. I have tried different diets, reduced food portions, increased physical activity, but my weight has remained the same. I am starting to think that maybe I am just counting my calories incorrectly. There is so much information on this topic on the Internet that I am already confused. Some say that you just need to eat less, others - that it is important to take into account the balance of proteins, fats and carbohydrates. Do you think it is really necessary to accurately count calories? Are there any proven ways to find out how many calories you need to lose weight? 

Indeed, in order to lose weight, it is important to understand how many calories you consume and how many you burn. To start, I recommend using the tdee calculator. This is a convenient tool that calculates how many calories you burn per day depending on your level of physical activity and other factors. You enter data such as weight, height, age and activity level, and the calculator shows you how many calories you need to maintain your weight, lose weight or gain weight. I used this calculator myself and was pleasantly surprised by the accuracy of the calculations. When you have a specific number, it is easier to plan your meals and workouts.
