When it comes to weight loss, many people struggle with maintaining the necessary healthy lifestyle in order to lose fat. Others manage to lose weight but struggle with stubborn areas of fat that remain no matter how much they diet and exercise.
In these cases, many patients turn to weight loss pills or surgery in order to achieve the desired loss of fat.
Unfortunately, these methods come with health risks and side effects. Red light therapy, also known as photobiomodulation, provides a safe, non-invasive alternative to address unwanted fat.

What is Red Light Therapy?

Red light therapy uses a low-powered red light to deliver wavelengths directly through the skin. The light is then absorbed by the cells, where it gives the mitochondria a boost and triggers the increased production of adenosine triphosphate (ATP).
This increase in ATP creates higher functioning cells that stimulate the body’s natural processes, resulting in benefits such as decreased inflammation, increases in blood flow, increases in collagen production, reduced effects of oxidative stress, and an increased ability to repair and restore damaged cells and tissue.
Numerous studies have examined the benefits of red light therapy in a variety of different applications.
For example, a 2018 randomised, triple-blind, placebo-controlled clinical trial published in Lasers in Medical Science looked at the use of red light therapy to treat acute pain and inflammation in patients that underwent total hip arthroplasty.
When compared to placebo patients, those receiving red light therapy showed decreased levels of inflammatory cytokines and decreased pain intensity.
Does Red Light Therapy Work For Weight Loss?
We know that red light therapy offers a wide variety of different health benefits, from reducing inflammation and the effects of oxidative stress to boosting the body’s natural healing ability. But what exactly does red light therapy do for weight loss?
In addition to boosting your cells with increased ATP production, red light therapy also affects adipocytes, or the cells that store fat.
Studies, such as the 2011 study published in Obesity Surgery, show that exposure to red light therapy causes the adipocytes to release triglycerides, resulting in reduced volume and a measurable loss of fat.
Participants in this 4-week study experienced a 2.15 cm loss in waist girth.
But the loss of triglycerides is not the only benefit red light therapy provides to patients trying to lose weight and improve body contour.
Studies Show Additional Weight Loss Benefits with Red Light Therapy
Red light therapy offers compelling benefits for weight management and body contouring, with clinical studies supporting its effectiveness over consistent treatment cycles. Beyond reshaping your silhouette, this advanced therapeutic approach delivers additional wellness advantages, enhancing your overall aesthetic results and supporting total-body rejuvenation.
- A 2012 study published in the International Journal of Endocrinology looked at the effects of light on leptin and ghrelin.
- Leptin is a hormone responsible for controlling appetite, helping to maintain body weight, and regulating how much energy the body burns.
- In contrast, ghrelin increases appetite and stimulates the release of growth hormone.
1. In this study, researchers looked at participants with poor sleep habits. Reduced sleep levels often increase the production of ghrelin while reducing the levels of leptin, often resulting in weight gain.
- Their research showed that exposure to red light significantly increased leptin levels while decreasing ghrelin.
- This reduction in hunger levels can have a great impact on those trying to follow a low-calorie diet for weight loss, helping to reduce hunger and the desire for snacking.
Another study looked at how red light therapy can provide additional benefits during regular exercise routines.
2.The study, published in Lasers in Surgery and Medicine, looked at the effects of light therapy on metabolic inflexibility when used with physical training.
During the study, 64 obese women were divided into two groups.
- The control group participated in exercise training while receiving a placebo light treatment.
- The second group participated in exercise training and received red light therapy immediately after exercise.
Both groups participated in three weekly sessions for 20 weeks. At the end of the study, researchers observed a greater reduction in fat mass and an increase in total skeletal muscles mass and adiponectin concentration compared to the control group.
While clinical research has shown how valuable red light therapy is for a variety of medical conditions, it is also highly beneficial for patients looking to lose weight, reduce fat, and imbody contour.
Red light therapy is a safe, non-invasive treatment option that provides effective results, helping patients achieve their weight loss goals.
Why Precision Matters in Red Light Therapy

Scientific research is conducted under strict conditions to measure the effectiveness of red light therapy, often focusing on individuals with a BMI of 25–30. This controlled approach ensures that findings are precise, but it also means that real-world results may vary based on individual factors like metabolism, lifestyle, and body composition.
At Aesthetic Bureau, we design our red light therapy machines with this as the mission, using the latest advancements to deliver optimised wavelengths and power output. While maintaining a healthy lifestyle is essential for achieving the best results, our high-performance machines are crafted to complement those efforts, providing a cutting-edge tool for body contouring and wellness.
Evidence for Red Light Therapy and Fat Loss
Key Findings from Research:
Red and Near-Infrared Light for Fat Loss
A study involving 55 participants found that red and near-infrared LED phototherapy combined with aerobic exercise significantly reduced abdominal fat.
The therapy was applied for 30 minutes, three times a week, for four weeks. The results showed it to be effective and safe without side effects (Lim, Lee, & Park, 2019).
Spot Fat Reduction
Another study found that red and near-infrared LED light therapy, combined with aerobic exercise, was effective in reducing localised fat deposits, particularly in the abdominal area. The participants who received the therapy experienced greater reductions in fat compared to those using sham devices (Lim & Park, 2018).
Photobiomodulation’s Role in Fat Loss
A broader review of photobiomodulation therapy (PBM) supports its effectiveness in fat loss, with outcomes depending on light wavelengths and pulsing frequencies (Lim, 2022).
Current evidence suggests that red light therapy, especially when combined with aerobic exercise, can be effective for fat loss, particularly in the abdominal area.
Considerations of Red Light Therapy for Fat Loss
Red light therapy is considered a safe, non-invasive treatment option that uses low-level wavelengths of light to target fat cells and improve body contour.
Unlike surgical procedures, it doesn’t involve incisions, anaesthesia, or lengthy recovery times, making it an appealing choice for many.
However, some individuals might experience mild side effects, such as temporary redness or irritation at the treatment site, though these typically resolve quickly.
People with sensitive skin or certain medical conditions, like photosensitivity, should consult a healthcare provider before starting, as light exposure could potentially cause discomfort.
Overuse or improper application might also lead to diminished results or minor discomfort. While the therapy is widely regarded as low-risk, it’s not a one-size-fits-all solution, and effectiveness can vary. For best outcomes and safety, professional guidance and realistic expectations are important.

FAQs
How Long Does It Take To See Fat Loss From Red Light Therapy?
When considering how long it takes to see weight loss from red light therapy, the timeline can vary depending on individual factors like body composition, lifestyle, and consistency of treatment.
Many people start noticing subtle changes within a few weeks of regular sessions, especially when paired with a healthy diet and exercise.
Red light therapy works by targeting fat cells and boosting metabolism, but it’s not an instant fix.
Visible results, such as reduced body contour or fat loss, typically become more apparent after a month or two of consistent use.
How Does Red Light Therapy Tighten Belly Skin?
Red light therapy is getting attention for its ability to tighten belly skin, offering a non-invasive way to improve body contour.
By penetrating the skin with specific wavelengths of light, it stimulates collagen production, which is key to maintaining skin elasticity and firmness.
As collagen levels increase, the skin on the belly can appear smoother and tighter, reducing sagging or looseness.
It also boosts circulation, promoting a healthier skin tone and texture. For those seeking a slimmer, more toned midsection, red light therapy provides a gentle yet effective option, improving the skin’s natural resilience without surgery.
How Often Should You Use Red Light Therapy For Weight Loss?
Consider using red light therapy for weight loss twice a week for better results. This frequency allows your body to experience the benefits of the therapy, such as reduced hunger and improved body contour, without overwhelming your routine.
Sessions can easily fit into a busy schedule, providing a consistent approach to support your weight loss goals. Pairing it with a healthy diet and exercise can enhance the results, making it a practical addition to your wellness plan.
Twice-weekly sessions offer a balanced way to use red light therapy’s potential for shedding pounds.
