Scientists uncover new protein that could change the future of weight loss and fat burning
Could a single protein hold the key to a new generation of obesity treatments? Mitch, please!That’s what scientists are saying and hoping after discovering the surprising role of MTCH2 — a protein they’ve nicknamed Mitch — that appears to have a major influence on how cells manage energy and store fat.In a new study, researchers discovered that disabling this protein supercharged the cells’ ability to burn carbohydrates and fat while also blocking the formation of new fat cells.This findings are especially exciting because they point to a potential new approach to obesity treatment that could also overcome the loss of muscle mass, one of the biggest drawbacks of today’s blockbuster weight loss drugs.The breakthrough has been years in the making.Researchers at the Weizmann Institute of Science first encountered Mitch’s surprising powers while studying mice.
When they suppressed production of the protein in the animals’ muscle tissue, they noticed something unexpected.The mice didn’t just stay lean.
They became remarkably resistant to obesity, developed more muscle fibers associated with improved stamina and athletic performance and performed better during physical stress tests.Researchers also observed improvements in heart function, suggesting the protein’s influence extended well beyond body fat.
These striking results motivated scientists to find out whether the same thing happened in human cells.Researchers found that removing Mitch effectively tricked cells into acting as though they were experiencing a constant energy shortage.
To compensate, the cells ramped up their fuel compensation, burning significantly more fats, carbohydrates and amino acids to keep up with their energy demands.In other words, disabling a single protein appeared to flip cells into a higher-energy, higher-fat-burning mode.Normally, cells tend to rely more heavily on carbohydrates and proteins as readily available fuel sources.
But cells without Mitch shifted mu...
