Scientists discover amino acid switch that turns fat into a calorie-burning furnace
Briefly

Caloric restriction reduces cysteine, an amino acid linked to fat metabolism, promoting weight loss. This process converts white fat cells into brown fat, which actively burns calories. Researchers, including Dr. Eric Ravussin and Dr. Krisztian Stadler, found that complete cysteine removal led to significant weight loss and enhanced fat burning in animal models. Cysteine also plays a critical role in maintaining redox balance within biological systems, indicating that manipulating its levels may provide innovative methods for weight management beyond traditional calorie control.
When study participants restricted their calorie intake, it resulted in reduced levels of cysteine in white fat, which sparked the conversion of white fat into brown fat.
Cysteine depletion triggers adipose tissue thermogenesis and weight loss, demonstrating an important role of cysteine in metabolism.
Removing cysteine drove high levels of weight loss and increased fat burning and browning of fat cells.
Cysteine is central to redox balance and redox pathways, suggesting potential future weight management strategies based on its modulation.
