Research suggests that red light therapy (635-850nm) may enhance fat metabolism, support weight loss, and improve overall body composition. It is believed to work by stimulating mitochondrial activity, increasing blood circulation, and promoting the release of stored fat from fat cells.
Key Findings from Multiple Studies:
- A 2013 study found that participants using 635nm red light therapy had measurable reductions in waist, hip, and thigh circumference over several weeks.
- A 2016 clinical trial showed that red light therapy combined with exercise led to greater fat loss compared to exercise alone.
- A 2020 review suggested that RLT may enhance mitochondrial function in fat cells, leading to increased energy expenditure.
- Some research indicates that red light therapy may reduce inflammation in adipose (fat) tissue, supporting metabolic health and insulin sensitivity.
Implications:
These findings suggest that red light therapy between 635-850nm may aid in fat loss, metabolic function, and body composition improvements. While not a replacement for diet and exercise, RLT may complement weight management efforts.
