Does at home red light therapy work for weight loss?

If you are looking for a natural and effective way to lose weight, red light therapy is a great option. Red light therapy is scientifically proven to help you shed pounds by reducing fat cells, curbing hunger, and ramping up your metabolism. Keep reading to understand how at-home red light treatments could be the solution to finally achieving the fit, healthy body you desire.

Obesity is a serious health problem that affects millions of people around the world. It is caused by a variety of factors, including genetics, diet, and lifestyle. Obesity can lead to a number of health problems, including heart disease, stroke, type 2 diabetes, and cancer. There are a number of treatments for obesity, including diet, exercise, and surgery. However, these treatments can be difficult to maintain, and they often do not lead to long-term weight loss. But with red light therapy, you can achieve your weight loss goals in a natural and sustainable way.

Understanding the Causes of Obesity

Before diving into how red light therapy promotes weight loss, it helps to first understand what typically leads to weight gain and obesity in the first place. Some of the most common causes include:

  • Hormone Imbalances: Excess cortisol and insulin resistance disrupt fat burning and increase storage around the belly. Estrogen dominance also encourages fat storage.
  • Poor Diet: Eating too many refined carbs, sugars, and processed foods leads to unstable blood sugar, increased hunger, and fat accumulation.
  • Low Activity Level: Not getting enough exercise slows your metabolism as you lose calorie-burning muscle mass. This makes it easier to put on weight.
  • Genetics: Your genes can predispose you to hold onto fat, especially around the midsection. This makes weight loss more challenging.
  • Slow Metabolism: A sluggish metabolism means you burn fewer calories at rest. This gets worse with age as metabolism naturally slows.
  • Chronic Stress: High cortisol levels increase appetite, fat storage, and accumulation of belly fat. This “stress weight” is hard to lose.
  • Lack of Sleep: Too little sleep decreases leptin, the satiety hormone. This leads to increased hunger and poorer food choices.
  • Medications: Some prescription meds like steroids, SSRIs, and birth control pills list weight gain as a common side effect.

As you can see, multiple factors are often at play when it comes to excess weight and obesity. The key is addressing the root causes with a multifaceted approach. This is exactly how red light therapy supports lasting weight loss.

Understanding the Causes of Obesity

How does red light therapy work for weight loss?

Red light therapy, also called photobiomodulation or low-level laser therapy (LLLT), uses red and near-infrared wavelengths to stimulate cells and biological processes. This comprehensive effect provides multiple weight loss benefits:

Metabolic Boost

Red light absorbed by fat cells increases mitochondria activity and ATP production. This significantly boosts resting metabolic rate so you burn more calories around the clock.

Reduced Inflammation

The light reduces inflammatory cytokines while increasing anti-inflammatory adiponectin. Lowering oxidative stress and inflammation helps normalize fat storage and hunger signals.

Fat Cell Shrinkage

Red light triggers fat cells to release stored triglycerides then flush them out via the lymphatic system. This shrinks fat cells around the waist, hips, thighs, and other areas.

Better Blood Sugar Control

Red light therapy improves glucose metabolism and insulin sensitivity. Keeping blood sugar stable means fewer carb and sugar cravings throughout the day.

Decreased Ghrelin

This hormone stimulates hunger. Red light therapy lowers ghrelin levels so you feel satisfied with smaller portions and experience fewer cravings.

Increased Satiety Hormones

LLLT raises levels of leptin and other hormones that suppress appetite and signal the brain that you are full and satisfied.

Improved Sleep Quality

The therapy enhances sleep by increasing melatonin and growth hormone levels. Quality sleep optimizes hormones for easier fat loss.

Reduced Cortisol

By lowering stress hormones like cortisol, red light therapy removes a major obstacle that triggers belly fat storage and weight gain.

Does at home red light therapy work for weight loss?

The consistent results across multiple studies and real-world users confirm red light therapy is highly effective at helping to lose stubborn body fat, slim your waistline, and keep it off long-term. Several studies have shown that red light therapy is effective for weight loss. A study published in the International Journal of Endocrinology found that red light therapy increased leptin levels while decreasing ghrelin levels, which can help reduce hunger associated with sleep deprivation[1]. Another study, published in the journal Obesity Surgery, found that red light therapy increased fat loss in adipocytes by releasing triglycerides, with subjects reducing waist circumference by -2.15 cm[2]. Another 2015 study showed that red light therapy combined with exercise can significantly reduce body weight, body fat percentage and waist circumference[3].

These studies suggest that red light therapy is a safe and effective treatment for obesity. Red light therapy is easy to use and has no side effects.

how choose an at-home device for red light therapy for weight loss?

Choosing the right at-home device for red light therapy for weight loss depends on several factors, including your budget, the size and type of the device, the right wavelength, and the level of intensity you need. Look no further than Reddot’s red light therapy panels.

Reddot’s red light therapy panels are some of the most advanced and effective on the market. Our panels emit light in the optimal range of 600 to 700 nanometers (nm), which has been scientifically proven to promote cellular metabolism and support weight loss. But that’s not all – our panels are also designed for Dual Wavelength Efficiency. Combining therapeutic red (660 nm) and near-infrared (850 nm) LEDs generates enhanced biological effects in less time. This dual-wavelength approach provides more efficient results for patrons and patients. RedDot also has over a decade of experience, all RedDot products have passed FDA certification, safety can be guaranteed.


So what are you waiting for? With its proven effectiveness, safety, and convenience, at-home red light therapy panels are the perfect solution for those looking to achieve their weight loss goals. Say goodbye to expensive gym memberships and diets and hello to a more cost-effective and convenient option for weight loss.


How long to do red light therapy for weight loss?

Many studies suggest that 10-30 minutes of red light therapy per day, a few times per week, can lead to significant weight loss results. It’s important to be consistent with your routine for the best results.

Who should avoid red light therapy?

Pregnant women, people with epilepsy, and those with certain medications or conditions that cause photosensitivity should consult with a healthcare professional before use.

Are there any negative side effects from red light therapy?

No, there are no known negative side effects from red light therapy. It’s a safe and non-invasive option for weight loss.
