OK, here’s the deal.
Yes there have been several (4 that I know of) studies showing that Brown Fat Exists in humans.
Even in adult humans.
It looks like we do have a tiny little bit left, mostly behind our shoulder blades and behind our clavicles.
And, YES it’s true, because of it’s high mitochondria content and the fact it expresses UPC1, brown fat cells actually burn energy (as opposed to just being an energy storage unit).
In fact, many proteins found in brown fat cells that are involved in fat uptake from the blood and fat combustion are more similar to those found in muscle.
Now, it’s dose of reality time.
In small mammals, exposure to cold stimulates the sympathetic nervous system to release the hormone adrenaline, which triggers brown fat cells to consume more fat and glucose for heat production…and it looks like brown fat plays the same role in humans. […]
