editAdult humans (at least the vast majority) do not have brown adipose tissue. So what is it that the thermogenics are actually doing? Harperska 21:58, 16 September 2006 (UTC)
- Aren't thermogenics supplements that supposedly increase metabolism and burn body fat. I don't know anything about brown adipose tissue vs white, but I have heard claims made by manufacturers about ingredients like ephedra. Maybe the article shoudl focus on those claims. Brad T.

why is there a random uncited comment about the ancient vikings and thermogenics? I highly doubt they used it as a thermogenic, if anything it was probably some test of manliness or a pres-sauna treatment like they do in the nordic countries now by jumping into freezing bodies of water before going into the sauna...moomoo2u —Preceding unsigned comment added by 69.157.227.183 (talk) 06:06, 15 November 2007 (UTC)
I think this article should be merged into a "weight loss supplements" article, with sections on cortisol blockers, appetite suppresents, etc. I think a lot of users would find a page like this with proper citations very useful. Le kasydzu (talk) 19:44, 18 May 2012 (UTC)
@Harperska: In fact new researches have shown that adults also have Brown fat tissue, of course in less amount than infants. Further, thermogenics, i.e. thermogenesis for human, do not happen just in brown fat tissue. See the reference I have added in the main article.

"recent studies have shown that adult humans maintain potentially active brown adipose tissue (BAT), making this highly energetic tissue a real therapeutic target"[1]

Methane section removal
editI removed the section on methane, see below. Thermogenics is not really a term used in geology, although Thermogenic is sometimes, but only in the sense that something was generated with heat (and it does not have to be methane). Methane formation is covered in a number of places on WP. It also seems that this page is about "stimulants which produce heat" and therefore the intent was not to talk about non-specific term in geology
Start removed section
Methane
Thermally generated methane (CH4) is referred to as thermogenic, originating from deeper sedimentary strata.[1] Thermogenic methane formation occurs due to the break-up of organic matter, forced by elevated temperatures and pressures. This type of methane is considered to be the primary methane type in sedimentary basins, and from an economic perspective the most important source of natural gas. Thermogenic methane components are generally considered to be relic (from an earlier time). The more important source of methane at depth (crystalline bedrock) is abiotic, meaning that the methane formation took place involving inorganic compounds, without biological activity, magmatic or created at low temperatures and pressures through water-rock reactions.[2] End removed section
