Fat reduction is becoming a big problem in current-day society due to high caloric intake and lack of exercise. Excessive accumulation of fatty tissue around the belly, chest, and thighs causes personal dissatisfaction with one’s physique and various health problems. As a result, people are looking for effective, safe, and simple procedures to modify body contours.

Traditionally, liposuction was the most popular method of modifying body contours. However, this invasive treatment was associated with many side effects and complications like fluid accumulation, numbness, infection, fat embolism, and even death, among others. That’s why non-invasive alternatives have come into use.

One of the most popular methods is the use of fat-burning machines based on light therapy. These are calling more and more attention because of their effectiveness, fewer complications, and ease of use.

In this article, we will look at fat-burning machines, the scientific evidence behind this method, its effectiveness, benefits, and the best devices.

What is a fat-burning machine?

Fat-burning machines are an increasingly popular weight loss method that includes non-invasive treatments using specific wavelengths of light to emit blue, red, or even infrared light (600 to 1000 nm). These devices also work with radio waves, previously used to treat periorbital wrinkles, rhytids, and skin laxity. In this new application, radiofrequency can penetrate the skin and help to eliminate fat cells.

As you can see, this type of wellness therapy is not new because it works well to treat various health problems. However, its use for weight loss is a novelty, and most related research dates from has the past 20 years.

How does fat-burning machine work

Fat-burning machines work using low-level light therapy (LLLT)  in combination with radiofrequency (some of them). LLLT initially treated other problems related to neurologic, ophthalmic, dental, and dermatological issues. The emitted light could help increase the local metabolic rate, since red and infrared light stimulates the mitochondria (the cell’s energy source), leading to more ATP production.

For fat reduction, devices usually apply a wavelength of 635 nm. The mechanism of LLLT in fat reduction consists of the generation of small openings in the cell membrane of adipose cells to release fats and excrete them. According to this, manufacturers recommend using some supplements (e.g., green tea, vitamin B5) to improve circulatory and lymphatic systems contributing to fat elimination.

On the other hand, some of these devices also work with radiofrequency, which main functioning principle is electromagnetic waves. These waves increase deeper skin temperature helping to contract the skin, and reducing body fat, in repetition, including cellulite.

Devices like Carer Spark combine wavelengths, frequently used in light therapy, with radio frequency that increases collagen production, lifts the skin, and removes wrinkles.

Effects of red and near-infrared light on fat reduction

Light therapy also affects thyroid function, which is closely related to body weight. The thyroid gland is a gland that produces certain hormones in the body (T3, T4, calcitonin), many of which are related to metabolism and weight gain or loss.

Red light therapy promotes proper regulation of thyroid function.

In addition to the observed acceleration of metabolism and thyroid regulation, red and infrared light also improves blood flow in the affected area.

This vasodilator effect is due to the following factor: the wavelength of red light helps release nitric oxide molecules, providing an important nutrient like oxygen, which in turn will result in improved blood flow.

Fat tissues in our body have limited access to blood, so improving blood flow through different layers of fat is important for burning fat.

These benefits of red light therapy work together to help you burn fat and lose weight.

How effective is a fat-burning machine? Based on clinical trials

Red and near-infrared light therapy is a non-invasive treatment for a wide range of conditions and now has another application: weight loss.

To date, several studies have shown that low-level laser therapy (LLLT) in combination with radiofrequency or near-infrared light by itself, can help to reduce localized fat.

A randomized placebo-controlled study involving 67 participants,  randomly assigned them to low-level laser treatment (635 nm) or a corresponding sham treatment six times for two weeks. As a result, participants in the laser-used group showed a 3.5″ reduction in total circumference in the evaluated areas: waist and hips, compared to the control group, which showed a 0.7″ reduction [1].

Pre-workout with near-infrared light therapy reduces loss of strength. Therefore, this kind of therapy may be a useful non-invasive method for improving muscle function, as supported by the following study [2].

Larkin-Kaiser and peers recruited 39 participants to use a laser device that emits infrared light at two wavelengths: 800 and 970 nm. Each patient received a 4-minute treatment. The results showed that infrared light treatment improves contractile function, as well as increases the number of repetitions and the time required for muscle fatigue.

The following study, performed by Munhoz et al., compared the effects of exercise and red light therapy post-exercise. The use of red light post-workout results in a greater reduction in body fat than exercise alone. Insulin sensitivity has also increased, which means that what you eat is less likely to be stored as fat and more likely to accumulate in your muscle tissue [3].

Light therapy improves cell activation, which is necessary for fat metabolism and therefore in cellulite treatment.

The study of Rossi and collaborators involved 20 women. They were divided into two groups: the control group, which performed only the treadmill workout, and the LED group, with light therapy during the treadmill workout. The training was carried out for 45 minutes twice a week for three months. The group treated with light therapy achieved more noticeable positive effects in the cellulite treatment than the group that only did the treadmill workout [4].

Jackson and peers conducted a study to evaluate the effectiveness of a low-level laser light device in improving the appearance of cellulite on thighs and buttocks. A total of 68 participants were recruited to undergo sham treatment or with an LLLT device for two weeks. As a result, 62,1%  of patients treated with LLLT (62.1%) were completely or partially satisfied with cellulite improvement compared to the sham group [5].

Later, in another study, these same authors confirmed the effectiveness of weight loss with light therapy by evaluating 689 participants exposed to light radiation. Participants underwent a total of six LLLT procedures over two weeks. After one week of treatment, the average decrease in the waist, hip, and hip circumference was 3.27″. In addition, participants showed an average reduction of 5.17″ in all the measurement points (waist, hips, arms, knees) [6].

These findings suggest that low-level laser therapy may be effective for body contouring, reducing the circumference of treated areas. LLLT helps with the loss of strength during exercise, which helps to retard muscle fatigue. And also, light therapy has a positive effect on the treatment of cellulite.
