Brown fat

Brown fat, or brown adipose tissue, is a special type of fat found in humans that generates heat to help regulate body temperature. Unlike white fat, which stores energy, brown fat burns calories to produce warmth, especially in cold environments. It contains many mitochondria—tiny powerhouses—that give it its brown color. This tissue is more prevalent in infants and some adults, and activating brown fat can aid in energy expenditure. Researchers are exploring its potential role in weight management and metabolic health, making it an interesting target for obesity and diabetes treatments.
