Obesity remains a significant global health challenge, contributing to a range of serious conditions including cardiovascular disease and type 2 diabetes. Now, emerging research suggests a potential new avenue for tackling this complex issue: harnessing the power of plant-based compounds known as polyphenols. A recent doctoral thesis from the Universidad Miguel Hernández de Elche (UMH) in Spain indicates that these naturally occurring substances may support the body burn fat more efficiently by transforming white fat cells into energy-burning brown fat cells.
The study, led by Irene Concepción Pomares Bri, focuses on the potential of polyphenols – bioactive compounds found in many fruits, vegetables, and other plants – to address the metabolic imbalances associated with obesity. This research builds on a growing body of evidence highlighting the role of brown fat in regulating metabolism and energy expenditure. Understanding how to activate and increase brown fat activity could offer a complementary approach to traditional weight management strategies like diet and exercise.
Polyphenols, known for their antioxidant and anti-inflammatory properties, appear to influence the function of different types of fat tissue. “Notice different types of fat in the body: white adipocytes, which store energy and also insulate our organs; and brown adipocytes, which are smaller and use energy to produce heat and regulate body temperature and blood glucose levels,” explained the researcher. Excess white fat contributes to overweight and obesity, while brown fat actively burns calories through a process called thermogenesis, according to the study.
The research involved a multi-phased approach. Initially, researchers simulated obesity in human cells grown in a laboratory setting. “We exposed human adipocytes to high concentrations of glucose for two weeks. The cells became hypertrophic, meaning they increased in size and showed altered function, replicating a metabolic environment similar to that of obesity,” Pomares Bri explained. In this model, several polyphenolic compounds were able to reverse the metabolic alterations caused by excess glucose and restore a healthier cellular profile.
Further analysis using “omics” techniques – a comprehensive approach to studying molecules within cells – helped identify specific metabolic pathways affected by high glucose levels and how polyphenols contribute to their repair. The team identified three natural compounds particularly effective at activating protein UCP1, responsible for heat production in brown fat. This discovery is a key step toward developing targeted interventions.
To validate these findings, a pilot study was conducted with adults who were overweight or obese. Researchers utilized infrared thermography, a non-invasive imaging technique, to observe temperature changes in the participants’ necks – an indirect indicator of brown fat activation and increased energy expenditure. The volunteers consumed a supplement containing extracts from two plants for three months. The study found that the supplement activated brown fat, as evidenced by the temperature increase, and when combined with a controlled diet, participants showed improvements in body weight and blood glucose levels.
These findings suggest a potential pathway for developing “nutraceuticals” – supplements based on compounds found in foods – as complementary tools for managing obesity and diabetes. “The idea is not to replace diet and exercise, but to offer additional support based on scientific evidence to improve metabolism and naturally increase calorie burning,” the researcher concluded.
The work, titled “New therapeutic approaches for the modulation of metabolic homeostasis in adipose tissue,” was defended on February 24th at the Instituto de Investigación, Desarrollo e Innovación en Biotecnología Sanitaria de Elche (IDiBE UMH) and supervised by María Dolores Herranz López and Vicente Micol Molina. The research was funded by the Generalitat Valenciana through project PROMETEO/2021/059 and the Ministry of Science, Innovation and Universities’ FPU/21/497 program.
This research is part of the UMH’s ‘Natural Bioactive Compounds’ group, which focuses on studying plant-derived molecules with therapeutic potential for metabolic and chronic diseases. The potential for polyphenols to influence fat metabolism represents a promising area for future investigation, offering a potential new tool in the fight against obesity and related health problems.
