What a fantastic post
One of the first health posts on Steemit that had a slight bit of depth to it
Your spot on in your observations but there is so much more to this topic that you should look into
The UCPs sit in the Mithocondria and are "fed" by the protons we pump out from the matrix and into the inter-membrane space
at the same time you have to understand what happens before pepole get start to accumulate visceral fat/Inflamation
Deterium in the Mithocondrial Matrix is what slows metabolismen and you can actually get a very good idea how well your Mithocondria are working by some cheap blood labs such as HS-CRP and Reverse T3
Reverse T3 is not part of most thyroid but can be tested for as little as 50USD at most doctors you just have to ask for it
I wrote an introduction blog about Leptin (the more in depth part about deterium is to come)
It has alot of links to further reading which I think you will love
