The Exercise and Obesity Health Promotion (PESO) program is a randomized controlled trial designed to analyze the effects of a lifestyle intervention in weight management and health-related parameters of overweight and obese premenopausal women
The PESO (Exercise and Obesity Health Promotion Program) is a program of weight control and exercise promotion for overweight and obese premenopausal women, developed by specialists in exercise, nutrition, and psychology, under medical supervision. It is a program that promotes the autonomy of the participants and the permanent modification of their habits and lifestyles, without the use of drugs or any other products, devices, or techniques of "slimming".
Participants in the PESO Program were able to enjoy a regular and multifaceted group program, aiming to increase knowledge about permanent body weight control, increased motivation and practice of physical activity and exercise, and improved habits food and nutrition. Increases in functional mobility, metabolic health, quality of life and the physical and mental well-being of the participants are central priorities of this Program.
The PESO Program was conducted in a university context and was led by teachers and researchers from the Faculty of Human Motors and other national and foreign institutions. The program is not for commercial purposes, it does not entail financial costs for the participants and it is involved in a wide range of scientific research projects, which have been recognized by individuals and external entities as relevant and of interest to the general population and the community in particular.

The SF-36 is a 36-item, generic quality-of-life measure that assesses 8 domains: (1) physical functioning; (2) role limitation due to physical-health problems; (3) bodily pain; (4) general health perceptions; (5) vitality; (6) social functioning; (7) role limitations due to emotional-health problems; and (8) mental health. Social function, vitality, and general health perceptions scales measure both physical and mental health status. All health measures were scored on scales of 0 to 100, with higher scores indicating better health. | 0 months |

| Physical activity | A self-reported measure of physical activity was used, specifically the short-form of the International physical activity questionnaire (IPAQ-SF). The IPAQ-SF records the last 7 day recall for four intensity levels of physical activity which is vigorous-intensity activity, moderate-intensity activity, walking, and sitting. From IPAQ data were converted to Metabolic Equivalent minutes per week (MET-min/week) using the published formulation the Compendium average MET score. Physical activity of low intensity was characterized by activities inducing less than 3 metabolic equivalents (MET), moderate intensity between 3 and 5.9 MET and for vigorous intensity higher than 6 MET. The higher the number of MET, the higher the intensity. The duration of the activities in each intensity were calculated based on the reported time per week. The higher the duration in activities of moderate to vigorous physical activity the highest the physical activity level | 0 months |
