Conditions

Accumulation of Adipose Tissue in Abdomen. hyperplasia of the abdominal fat tissue (abdominal skin folds higher than 20 mm).

Interventions

The abdomen of the participants will be cleaned by using a neutral cleansing soap. They will receive eye protection, using goggles for safety. This will also help with the blindness of the study. PBM
Group B—INFRARED 830±10 nm
Group C—PLACEBO. The treatment will consist of eight sessions that will occur two times a week, totalling 1 month of treatments. The placebo group will use a strap with no light emission, but it will

Design outcomes

Primary

MeasureTime frame
The reduction of abdominal circumference, which will be evaluated through an inelastic anthropometric tape. Measurements will be performed on day zero and after the eighth treatment session and fifteen days after the last session.

Secondary

MeasureTime frame
Observe for changes in lipid profile and markers of liver function after treatment. Measurements will be performed through biochemical blood analysis to be performed on day zero and after the eighth week of treatment and after fifteen days of the last session.;Observe the improvement of quality of life after treatment. The Quality of Life questionnaire will be applied on day zero after the eighth session of treatment and fifteen days after the last session.;Check if there is improvement of the fat percentage through the bioimpedance technique. Measurements will be performed on day zero after the eighth treatment session and fifteen days after the last session.;Observe if there is a reduction in the thickness of the fat layer that will be measured by ultrasonography. Measurements will be performed on day zero and after the eighth treatment session and fifteen days after the last session.;To verify if there is improvement in the self-assessment of the body image, which will be measured through a specific questionnaire. Evaluations will be performed on day zero and after the eighth treatment session and fifteen days after the last session.
