Red light therapy, a treatment primarily used for skin tightening, is gaining attention as a potential method for weight loss. Though it’s not widely recognized as a first-line solution for fat loss, some believe that it could help reduce fat and contour the body without the need for changes to diet or exercise. But does it work? Experts weigh in.
What is Red Light Therapy?
Red light therapy, also known as low-level laser therapy, involves shining a red wavelength of light onto the skin. This non-invasive treatment is typically used for various health concerns, including skin issues and pain management. In terms of weight loss, it’s considered a body-sculpting method, designed to break up fat cells beneath the skin. “The goal is to target subcutaneous fat, which lies just below the skin’s surface, and break down fat cells so the body can remove them,” explains Mir Ali, M.D., medical director of MemorialCare Surgical Weight Loss Center.
Does Red Light Therapy Help With Weight Loss?
While some research supports its use for fat loss, the evidence is not robust. Dr. Ali suggests that red light therapy is more useful for body contouring rather than significant weight loss. When fat cells are broken down, the body absorbs their contents, and the fat cells typically don’t regenerate. However, weight loss results from red light therapy are often modest.
A few studies have explored red light therapy for weight loss. One study found that participants who underwent red light therapy treatments twice a week for six weeks lost about two centimeters from their waist. In another trial, participants lost about 3.5 inches from their stomach, hips, and thighs after six treatments over two weeks. However, results varied, and some participants gained back some of the fat two weeks later.
Red Light Therapy Risks
Although generally safe, there are some risks associated with red light therapy. If the laser makes direct contact with the skin, there can be a risk of skin damage. Additionally, these treatments can be expensive, with costs often running into the thousands. There’s also a chance that red light therapy may not work for everyone, and any weight loss that does occur may be minimal or temporary.
How Long Does It Take to See Results?
Results from red light therapy vary. Some individuals report seeing a reduction in fat after as little as two weeks of frequent treatments, but the effectiveness of the therapy is inconsistent.
Does Red Light Therapy Tighten Skin?
In addition to potential fat loss, red light therapy is frequently used in dermatology to stimulate collagen production, tightening skin and making it appear firmer. This could be particularly beneficial for those looking to improve skin appearance, especially in areas like the belly.
Can You Overdo Red Light Therapy?
Yes, excessive use of red light therapy can lead to irritation or even burning due to prolonged light exposure. Experts recommend avoiding overuse to prevent skin damage.
Conclusion
While red light therapy can be effective for body contouring and tightening skin, it’s not a magic solution for significant weight loss. Experts agree that it can help with modest fat loss and may be useful for reshaping certain areas of the body, but it’s unlikely to be effective for sustained or substantial weight reduction on its own. It’s important to approach this therapy as a supplementary tool rather than a primary weight loss method.
