Liposuction is currently the fastest weight-loss method, allowing targeted fat removal wherever desired, making it popular among beauty-conscious women. However, a recent U.S. study found that while liposuction helps reduce body weight, it offers no preventive or therapeutic benefits for obesity-related health issues like cardiovascular disease or diabetes.
The research was conducted by scientists at the Human Nutrition Research Center at Washington University School of Medicine in St. Louis.According to lead researcher Professor Samuel Klein, the study initially aimed to uncover new evidence supporting liposuction's health benefits. The findings, however, proved surprising. They discovered that while this cosmetic procedure enables rapid weight loss, it does not alter metabolic function. Unlike diet and exercise-based weight loss, this method offers no positive effects in preventing or treating obesity-related diseases.
Professor Klein and his team studied 15 "super" obese women. They underwent liposuction to remove nearly 20% of their subcutaneous fat—four times the amount typically extracted in standard liposuction procedures.Ten to twelve weeks later, researchers measured indicators of cardiovascular disease and diabetes risk in these women, including cholesterol, triglycerides, glucose, and insulin levels. The results showed no improvement in these indicators compared to pre-surgery levels. Regarding this, the researchers suggested one possible explanation: liposuction only removes subcutaneous fat from obese individuals, which is precisely the type of fat posing the least threat to health.Animal studies indicate that visceral fat accumulation is the primary culprit behind high blood lipid levels. This deep-seated fat reduces the body's insulin sensitivity, increasing diabetes risk. It may also secrete inflammatory substances that trigger cardiovascular disease.These substances can also directly enter the liver, impairing its ability to regulate blood sugar and cholesterol levels. In contrast, weight loss achieved through diet and exercise rapidly reduces fat in the liver, muscles, heart, and abdominal viscera. In such cases, even modest weight loss can significantly improve health outcomes.
Previous studies suggested that liposuction not only reduces weight in obese individuals but also lowers their risk of obesity-related diseases like heart disease and diabetes. Many practitioners have heavily promoted liposuction's "health benefits" to attract more patients.Klein and colleagues explain that many liposuction patients are instructed to diet and exercise post-surgery to prevent weight regain, a factor past studies may have overlooked. In contrast, the University of Washington medical researchers' experiment strictly prohibited volunteers from dieting or exercising after surgery. Professor Klein states that liposuction is at best a cosmetic procedure with no health benefits whatsoever.
