Intervention type: BEHAVIORAL
Group type: SHAM_COMPARATOR
Intervention: Dietary
Description: The dietary therapy will be performed every 15 days, totaling 6 sessions of 60 minutes each by a dietitian. Patients will be advised to follow restricted-calorie diet based on the hypocaloric dietary guidance, multiplying the patient's weight by 20 to 25 calories. The Nutwin ® program will be used to structure the patient's diets, based on 24 hours food record and calories tables. Throughout the program, issues related to food control, the benefits of following a balanced diet and the changing food habits will be discussed.

Intervention: Behavioral Therapy
Description: The Behavioral therapy will be performed every 15 days, totaling 6 sessions of 60 minutes each by a psychologist. Sessions of group dynamics will be performed to increase the patient adherence in a weight loss program using behavior modification techniques, such as self-management, motivational strategies, positive reinforcement and relapse prevention. Relaxation techniques, experiences and patient's report will also be used.

Intervention: Exercise Training
Description: The aerobic training will be performed on a treadmill and a bike (or an elliptical), twice a week, totaling 24 sessions of 60 minutes each. The initial intensity will be 50% to 60% of VO2 max reaching a maximal 75% of VO2 max and the progression will take place according to the level of effort (Borg) in the last two sessions. Patients will be advised to walk outside at least twice a week for 30 minutes and write down their activity in a diary. Furthermore, they will be given an accelerometer in week 6 to record their daily steps. The resistance training will consist of exercises for the upper and lower limbs. Initially, the patients will perform 2 sets of 10 repetitions with load of 50% to 70% of 1-RM and the progression will take place in the number of repetition, and then in the load.

Intervention: Stretching and Breathing exercise
Description: Breathing exercise will consist of 3 exercises adapted from yoga's breathing technique (kapalabhati, uddhiyana and agnisara) twice a week, totaling 24 sessions of 30 minutes each. Every exercise will be performed in sets of 3 (2 minutes each) with 60 seconds of rest between them. The stretching will consist of stretching exercises for the major muscle groups in 3 sets of 10 seconds each. The program will be performed twice a week, totaling 24 sessions of 30 minutes each.~\*Both breathing and stretching exercises will be performed as placebo to ensure the same duration of treatment between the two groups.
