Abstract

Recently, investigations suggest the benefits of low-level laser (light) therapy (LLLT) in noninvasive treatment of cellulite, improvement of body countering, and control of lipid profile. However, the underlying key mechanism for such potential effects associated to aerobic plus resistance training to reduce body fat and inflammatory process, related to obesity in women still unclear. The purpose of the present investigation was to evaluate the effects of combined therapy of LLLT and aerobic plus resistance training in inflammatory profile and body composition of obese women. For this study, it involved 40 obese women with age of 20-40 years. Inclusion criteria were primary obesity and body mass index (BMI) greater than 30 kg/m2 and less than 40 kg/m2. The voluntaries were allocated in two different groups: phototherapy group and SHAM group. The interventions consisted on physical exercise training and application of phototherapy (808 nm), immediately after the physical exercise, with special designed device. Proinflammatory/anti-inflammatory adipokines were measured. It was showed that LLLT associated to physical exercise is more effective than physical exercise alone to increase adiponectin concentration, an anti-inflammatory adipokine. Also, it showed reduced values of neck circumference (cm), insulin concentration (μU/ml), and interleukin-6 (pg/ml) in LLLT group. In conclusion, phototherapy can be an important tool in the obesity, mostly considering its potential effects associated to exercise training in attenuating inflammation in women, being these results applicable in the clinical practices to control related risk associated to obesity.

Abstract

BACKGROUND:

Low-level laser therapy (LLLT) is commonly used in medical applications, but scientific studies of its efficacy and the mechanism by which it causes loss of fat from fat cells for body contouring are lacking. This study examined the effectiveness and mechanism by which 635–680 nm LLLT acts as a non-invasive body contouring intervention method.

METHODS:

Forty healthy men and women ages 18–65 years with a BMI <30 kg/m2 were randomized 1:1 to laser or control treatment. Subject's waistlines were treated 30 min twice a week for 4 weeks. Standardized waist circumference measurements and photographs were taken before and after treatments 1, 3, and 8. Subjects were asked not to change their diet or exercise habits. In vitro assays were conducted to determine cell lysis, glycerol, and triglyceride release.

RESULTS:

Data were analyzed for those with body weight fluctuations within 1.5 kg during 4 weeks of the study. Each treatment gave a 0.4–0.5 cm loss in waist girth.Cumulative girth loss after 4 weeks was ?2.15 cm (?0.78 ± 2.82 vs. 1.35 ± 2.64 cm for the control group,p < 0.05). A blinded evaluation of standardized pictures showed statistically significant cosmetic improvement after 4 weeks of laser treatment. In vitro studies suggested that laser treatment increases fat loss from adipocytes by release of triglycerides, without inducing lipolysis or cell lysis.

CONCLUSIONS:

LLLT achieved safe and significant girth loss sustained over repeated treatments and cumulative over 4 weeks of eight treatments. The girth loss from the waist gave clinically and statistically significant cosmetic improvement.

Abstract

A previous study has shown that laser acupuncture is a useful healing method for the treatment of visceral postmenopausal obesity in combination with a low-calorie diet. We observe and evaluate the therapeutic effect of laser acupuncture in subjects of simple obesity with a non-restrictive diet protocol. Subjects included 73 women and 22 men with simple obesity and body mass indices > or = 27 kg/m2. Daily energy intake recommendations for obese females and males were 1620.0 and 1894.2 kcal in average, respectively. The gallium aluminum arsenide Handylaser Trion was used to apply 0.25 J of energy to each of the following acupuncture points three times per week for four consecutive weeks: Stomach, Hunger, ST25, ST28, ST40, SP15, and CV9. The subjects' body weights and body mass indices were recorded before treatment, and four weeks after treatment, and the percent reduction in each parameter was calculated. Statistically significant reductions in body weight and body mass index were detected after four weeks of treatment. The mean reduction and mean percent reduction in body weight were 3.17 kg and 3.80% (p < 0.0001), respectively. The corresponding values for the body mass index were 1.22 kg/m2 and 3.78% (p < 0.0001), respectively. We concluded that laser acupuncture was found to exert a therapeutic effect on simple obesity by reducing both body weight and body mass index. Moreover, subjects showed good compliance with this comfortable and non-restrictive diet protocol.

Abstract

BACKGROUND: To compare the efficiency of low-calorie diet and low-calorie diet applied together with laser acupuncture in the therapy of visceral obesity in postmenopausal women.

METHODS: The study population consisted of 74 postmenopausal females with visceral obesity who were divided into two groups according to an employed 6-month slimming procedure. In the first group (n = 36) a low-calorie diet was applied, while women in the second group (n = 38) were on the same kind of diet, having additionally one cycle of laser acupuncture procedure at the same time. At baseline and at the end of the study, body weight, body mass index and waist-to-hip ratio were determined in all women.

RESULTS: After 6 trial months both groups exhibited a statistically significant drop in body weight, body mass index and waist-to-hip ratio. The mean reduction of body weight, body mass index and waist-to-hip ratio was significantly higher in the second group of women (laser acupuncture plus low-calorie diet).

CONCLUSIONS: (1) Our results testify that the combination of a low-calorie diet and laser acupuncture is characterized by a higher efficacy than a low-calorie diet alone in lowering body weight, body mass index and waist-to-hip-ratio. (2) Laser acupuncture is an additional useful healing method in the therapy of visceral postmenopausal obesity.
