Method of study:

The review first begins with a history of laser light therapy. The principle working behind the technology and highlighting its effectiveness as a treatment for weight loss. The review also touches upon researches done on the subject in the past.

Finding:

The review concludes that while studies were previously done on the subject point to the safety and efficacy of LLLT in fat layer reduction, studies demonstrating the efficacy of LLLT as a stand-alone procedure are still woefully inadequate. More research on the subject is needed before human testing.

2. A controlled trial demonstrating the use of light therapy as a weight-loss treatment.

Number of participantsSixty-four(BMI 30-40 kg/m2, age between 20 and 40 years old) 

Method of study:

The study was carried out by choosing 64 obese women and each woman was placed in two groups. The two groups were Exercise Training plus SHAM group and Exercise Training plus Phototherapy group. The sham group and the phototherapy group were both required to exercise but only the phototherapy group received the light therapy.

Findings:

The results of the trial were mostly positive. The trials concluded that physical training plus phototherapy was more effective than physical training in reducing the delta of the percentage of fat mass. The exact results are given below:

 (%; -5.60 ± 1.59 vs. -4.33 ± 1.5; P < 0.04); fat mass (kg; -11.26 ± 2.82 vs. -5.80 ± 2.82; P < 0.0002); HOMA-IR index (-38.08 ± 9.23 vs. -20.91 ± 14.42; P < 0.0001). In addition, the trails observed an increase in delta (%) of total skeletal muscle mass (kg; 0.60 ± 1.09 vs. -1.38 ± 1.70; P < 0.003), adiponectin concentration (ng/ml; 1.08 (0.04-3.62) vs. -0.42 (-3.15 to 2.26); P < 0.03) in the same comparison.
