I linked this journal previously here: Coffee - More Good News! Browning Your Fat. It deserves its own topic. This is very interesting stuff. An excellent read!
I think the whole thing is both interesting and useful. For those who want to take the deep dive, there are 183 citations. But if you just want to skip to the conclusions, go here. There are a couple of technicolour diagrams, followed by Table 1, which is a list of substances and doses.
