Abstract:

Introduction Non-invasive focused low-frequency ultrasonic waves that reduce the circumference and volumes of areas with localized fat have become more popular. This study aimed to determine the effectiveness and safety of focused low-frequency ultrasonic waves in reducing localized abdominal fat deposits.

Methods This was a randomized, double-blind, placebo-controlled trial. Included in the study were Filipino adults with localized abdominal fat deposits. The primary outcome measure was mean change in abdominal circumference after 4 weeks of treatment, and secondary outcome measures were mean change in abdominal fat thickness, weight, serum lipid profile, as well as frequency of adverse events.

Results There was a significant reduction in the mean abdominal circumference and fat thickness among patients who received focused low-frequency ultrasonic waves compared to those in the placebo group. There were no significant differences in weight, total cholesterol, HDL, LDL, triglycerides, VLDL levels, and adverse events between the two groups.

Conclusion Focused low-frequency ultrasonic waves are effective in reducing abdominal circumference and fat thickness.
