Scientists Discover Cysteine 'Switch' for Fat Burning
Imagine your body has two kinds of fat.
White fat stores energy, and brown fat burns it for warmth.
Scientists found a special switch involving an amino acid called cysteine.
When cysteine is low, it changes white fat into brown fat, helping you lose weight.
This new finding might help people lose weight without just cutting calories.
Research was done on both people and animals.
Scientists found a biological switch involving the amino acid cysteine.
Reducing cysteine converts white fat to brown fat.
Brown fat burns calories to generate heat.
Study involved human and animal trials.
New therapies may target cysteine levels for weight loss.
