With all the attention on weight loss medications these days, many people are exploring alternative methods to shed fat, including red light therapy. While this approach has been gaining popularity as a possible weight loss tool, the evidence is still mixed. Here’s what we know from experts and available research.
What is Red Light Therapy?
Red light therapy, also known as low-level laser therapy, involves shining red light from the light spectrum onto the skin. This non-invasive procedure is used to treat a variety of health conditions, including body sculpting for fat reduction.
During the treatment, a laser targets the fat beneath the skin’s surface, known as subcutaneous fat. The idea is to break down fat cells, which the body then absorbs and removes. Red light therapy is typically performed by a dermatologist, plastic surgeon, or weight loss specialist, and multiple sessions are usually required for noticeable results.
Does Red Light Therapy Work for Weight Loss?
While some research suggests red light therapy might be effective for weight loss, the results are not consistent or robust.
According to Dr. Mir Ali, medical director of MemorialCare Surgical Weight Loss Center, the therapy is more about body contouring than significant weight loss. It works by breaking up fat cells, and once fat cells are broken down, they typically do not grow back. However, red light therapy is generally seen as a body-shaping treatment, helping to reshape areas of the body rather than leading to large-scale weight loss.
Some studies show modest results. In one, participants who received therapy twice a week lost about two centimeters from their waist circumference. Another study involving 67 people found those receiving six sessions over two weeks lost an average of 3.5 inches from their stomach, hips, and thighs. However, participants gained back some of this fat after two weeks.
Red Light Therapy Risks
While red light therapy is generally considered safe, there are a few risks involved:
- Skin damage: Laser exposure can cause skin damage if it makes direct contact with the skin.
- Cost: Treatments can be expensive, with packages sometimes costing thousands of dollars.
- Limited effectiveness: Weight loss is modest, and the fat that is lost can return in other areas of the body.
How Long Does It Take to See Results?
The timeline for seeing results varies from person to person. Research indicates that some people begin to see changes after just two weeks of multiple weekly sessions. However, these results can be temporary and depend heavily on the individual’s body and consistency with treatments.
How Does Red Light Therapy Tighten Belly Skin?
Red light therapy is often used in dermatology to stimulate collagen production, which can tighten the skin and make it appear firmer. This is helpful for improving the appearance of skin that may have become loose, such as in the belly area after weight loss.
Can You Overdo Red Light Therapy?
Yes, overdoing red light therapy is possible. Excessive exposure can cause skin irritation or even burning. It’s essential to follow the recommended guidelines and consult with a professional.
Conclusion: Is Red Light Therapy Worth It for Weight Loss?
Doctors caution against relying on red light therapy for substantial weight loss. While it may help contour certain areas of the body and tighten skin, it is not a proven method for significant, lasting weight reduction. Dr. Ali and Dr. Rodney both emphasize that there is no compelling evidence to support red light therapy as a primary weight loss tool.
In summary, red light therapy can be a helpful adjunct to other weight loss methods, but it’s not a substitute for diet and exercise. If you’re considering it, be sure to consult with a healthcare provider to discuss its potential benefits and risks.
