A randomized controlled trial was conducted. Sixty-two women were initially enrolled in the experimental group and randomly assigned to the study group (with additional intervention) and the control group (without additional intervention), after informed written consent was obtained from these subjects. The women were recruited for the study from patients of the Metabolic Clinic. Two participants did not complete the therapeutic process due to health conditions that precluded participation. Randomization was conducted as a simple assignment (Excel; Microsoft, 2016 software), and the person performing it was not involved in the research process.All the study subjects were Caucasian and from the Wielkopolska region (Poland). Before entering the project, all the participants were obliged to strictly follow dietary recommendations and the diet individually prepared for use in the study by the included dietician. Those enrolled in the study during the project were asked not to perform additional physical activity beyond that carried out as part of the program. The examined women had not taken a part in a similar research project before.The investigated women were between 19 and 68 years of age, with a Body Mass Index (BMI) > 30 kg/m
