Proper nutrition - 70% success in achieving any fitness goal, whether it is losing weight or          gaining muscle mass. A small mistake can nullify all efforts. We understand how many calories the body needs in order to live in the mode you have chosen and in the current weight. Now, it is important to understand how many calories should be "given" to the body in order to force it to reorganize in the direction we need. If the goal is to burn fat, then the total calorie intake should be less than the required energy consumption - then the body will have to extract energy by burning fat. If the goal is to build muscle mass, then it is important to provide the muscles with a sufficient amount of building material. On the basis of the calculated calories, the diet is compiled: the volumes are distributed by meals depending on the life schedule, as well as by the ratio of proteins / fats / carbohydrates. Products suitable for each meal are selected. 

In such cases, a coach or specialist is needed who is able to organize and systematize the information received, help achieve the desired stable result, from the right habits and addictions.
