**Tokyo, Japan** – A groundbreaking study by a Japanese research team has identified protein variants that increase during exercise and contribute to fat burning. The findings, published in the European scientific journal *Molecular Metabolism*, could pave the way for a new drug that helps people lose weight without traditional dieting or exercise.
The team, comprised of researchers from Kobe University Graduate School of Medicine and other institutions, discovered that different versions of the PGC-1a protein are produced in skeletal muscle during exercise. The more these variants increase, the more energy the body expends.
Further research revealed that mice lacking these protein variants exhibited impaired energy expenditure during exercise, leading to obesity and insulin resistance. Notably, similar increases in alternative PGC-1a variants were observed in human skeletal muscle during exercise, suggesting a possible explanation for individual differences in weight loss despite similar exercise routines.
This discovery has significant implications for the treatment of obesity. While current approaches often focus on appetite suppressants, the research team believes their findings could lead to the development of new drugs that induce or increase these protein variants independently of exercise.
Professor Wataru Ogawa, a member of the Kobe University research team, emphasizes the potential of this research in addressing obesity-related illnesses, which represent a major healthcare concern. The development of effective weight-loss drugs could significantly contribute to treating a range of associated diseases.
The research highlights the intricate interplay between exercise and the body’s metabolism. While the findings offer hope for future drug development, the team emphasizes the importance of maintaining a healthy lifestyle, including regular exercise and a balanced diet.
