  "textContent": "Scientists at McGill University have uncovered a hidden molecular “switch” that turns on a powerful calorie-burning system in brown fat — the body’s heat-generating fat linked to metabolism and weight control. The breakthrough centers on glycerol, a molecule released when fat is broken down in the cold, which activates an enzyme called TNAP and triggers an alternative heat-producing pathway that scientists had struggled to explain for years.",
