The Benefits of Red Light Therapy for Weight Loss and Cellulite Reduction
Losing weight and fat is one of the most common health goals and whether your reasons are medical, cosmetic or a combination of the two… most of us could benefit from losing a few pounds and trimming some fat in some target areas. In this article we will provide an overview of clinical research revealing how natural red light therapy can help you:
• Lose weight
• Tone your body
• Reduce fat and cellulite
• Reduce hunger
• Control obesity.
How Does Light Therapy Work to Reduce Fat?
If you’re not familiar with light therapy, and are interested in learning How Red Light Therapy Works click the link. A device like the Fully-Body Joovv LED Light Therapy device delivers safe, concentrated wavelengths of therapeutic natural light to your skin and cells, where it reduces oxidative stress and stimulates cellular energy production (adenosine triphosphate or ATP). Not only does that help your body power itself more effectively, but researchers believe red light therapy affects adipocytes, which are cells that store fat, causing the lipids to disperse. In other words, light therapy helps the body wash away fat cells. 
Light therapy may work in other ways that affect fat and weight loss as well. A 2012 study in the International Journal of Endocrinology showed that light can affect hunger levels, which could help prevent the buildup of extra fat before it even begins. This study found that red light helped control appetite levels via the hunger-hormones, leptin and ghrelin in sleep-deprived participants. 
Leptin resistance, in which the body does not respond to this hormone, is now believed to be the leading driver of weight gain and obesity in humans.  Leptin is often referred to as the “satiety hormone” or the “starvation hormone”. It’s primary target is in the brain – primarily an area called the hypothalamus. Leptin is suppose to tell your brain that – when you have enough fat stored (energy surplus) – you don’t need to eat and can burn calories at a normal rate. 
Leptin’s main role is long-term regulation of energy, including the number of calories you eat and expend, as well as how much fat you store in your body.  Today, leptin is highly effective at keeping us from starving, however, for many of us leptin signaling is impaired and while high quantities of leptin may be present, the brain doesn’t recognize it.  This condition – known as leptin resistance – is now believed to be one of the main biological contributor to obesity. 
Clinical Research Shows Red Light Therapy Reduces Fat and Helps with Weight Management
Red light therapy’s positive effects on fat loss and cellulite reduction, obesity control, and cosmetic body enhancement have been demonstrated in numerous clinical trials. And unlike other solutions promoted for weight-loss, such as medications and surgery, red and near infrared light therapy is a safe, natural, and noninvasive option which only further promotes and enhances ones health and fitness.
Below is a brief overview of significant clinical research:
Less Cellulite: In a 2011 study on red light therapy and cellulite reduction, women ages 25-55 were divided into two groups: some performed treadmill exercise + infrared light therapy twice a week, while the other group only performed the treadmill exercise. The researchers presented thermographic photographs of the changes in thigh circumference and cellulite to demonstrate that red light therapy and exercise was significantly more effective than exercise alone. The study concluded that treadmill exercise and red light therapy in conjunction can improve body aesthetics. 
Cosmetic Body Contouring: Many people trying to lose weight simply wish to enhance their physical appearance. A wide variety of therapies are now available which target and eliminate fat cells and thereby improve appearance. These services, often referred to as “body contouring” or “body sculpting”, include surgical procedures, as well as noninvasive techniques such as CoolSculpting. While many of these option are initially effective, they are often expensive and fail to address the underlying issue and inevitably the unwanted fat returns. Red light therapy is a natural, noninvasive option that has proven to be an effective for not only changing the way your body looks, but helping to address the leptin resistance that is at the source of most people’s weight problems.
Smaller Waistline, Less Girth: A study in the Journal of Obesity Surgery researched red light therapy for body contouring. This 2011 double-blind, randomized study performed red light therapy at 635-680 nanometers (nm) on participants for four weeks and recorded effects on the size of their waistline. At the end of the study, participants had achieved a statistically significant reduction in waistline girth. 
Targeted Fat Loss: In a similar study published in Lasers in Surgery Medicine, participants who received red light therapy in the 635 nm range showed a significant reduction in overall circumference, including numerous parts of the body. Researchers concluded that light therapy can reduce the circumference of the specific areas of the body that are treated with red light therapy. 
Tighter Hips & Thighs: A 2013 study in the same journal also found benefits from red light therapy for contouring the hips, thighs, and waist. At the end of the trial, researchers found a mean loss of 2.99 inches in overall body size compared to the starting point. Separately, the thigh, waist, and hip areas all showed a reduction too. Researchers concluded that red light therapy at this wavelength was safe and clinically effective (Figure A).

Less Body Fat: A 2018 triple-blind, placebo-controlled trial assessed red light therapy’s effects on people doing endurance training. Researchers found pre-exercise treatment can “decrease the body fat in healthy volunteers when compared to placebo.” 
Weight and Obesity Control: A study conducted by Brazilian researchers in 2015 assessed the effects of light therapy and exercise on 64 obese women, ages 20 to 40. One group exercised and received red light therapy treatments, while the control group simply exercised. They concluded that red light therapy and exercise together were more effective than just exercise in reducing fat mass. Researchers also observed an increase in skeletal muscle mass. They noted:
“Our results demonstrated for the first time that light therapy enhances the physical exercise effects in obese women undergoing weight loss treatment promoting significant changes in inflexibility metabolic profile.” 
A recent study published in 2018 also evaluated obese young women and found similar results. Some followed an exercise regimen combined with red light therapy, while the control group only performed the exercise. The women who performed the exercise in combination with the red light therapy saw more significant changes in fat mass and insulin variables.
“It was demonstrated that exercise training associated with light therapy promotes an improvement in body composition and inflammatory processes. The light therapy group especially presented positive modifications of WNT5 signaling, FGF-21, and ANP, possible biomarkers associated with browning adiposity processes. This suggests light therapy is applicable in clinical practice to control obesity.” 
A placebo-controlled clinical trial in 2015 noted similar improvements with obese women who exercised and were treated with red light therapy. Researchers also concluded red light therapy could control cardiometabolic risk factors in obese populations.
