Brown Fat: A Potential Weapon Against Obesity
Brown fat is a special kind of fat in our bodies that helps burn calories to keep us warm.
Unlike white fat, which is hard to lose, brown fat is easier to burn and gets activated when we feel cold.
Babies have a lot of brown fat to keep them warm, but as we grow older, the amount decreases.
Researchers have found that exposing adults to cold temperatures can increase brown fat.
There's also a protein called AC3-AT that can stop brown fat from working properly.
Scientists believe that understanding and activating brown fat could be a big help in fighting obesity.
Brown fat burns calories to generate heat, unlike white fat which stores calories.
Babies have large deposits of brown fat to keep them warm, making up 2-5% of their body weight.
As adults, brown fat is found around the neck, shoulders, spinal cord, kidneys, and heart.
Exposing adults to cold temperatures (15-16°C) for six hours a day can increase brown fat.
The AC3-AT protein inhibits brown fat activation and calorie burning, potentially hindering weight loss.
