[edit] I think we're all forgetting something important

Fat is not a naturally forming layer. It's a malignant substance that causes the body to develop AIDS, and should be eliminated from the body by any frantic method we can think of. Fat PEOPLE should be eliminated from the population, since their fat is contagious and can irradiate your pants. —Preceding unsigned comment added by 71.229.30.57 (talk) 14:34, 13 May 2008 (UTC)

[edit] Original discussion

A the request of someone on the Spanish-language wikipedia, I did my best here to translate the more extensive material on this topic from the Spanish-language wikipedia. This really needs review now by a competent biologist, because I am a total layman attempting translation of technical material.

Also, in searching for vocabulary I came across http://www.lab.anhb.uwa.edu.au/mb140/CorePages/Connective/Connect.htm, which looks to my layman's eyes to be very solid and informative. I suspect it is a good mine of information and that one or more articles should include it in their external links. However, since it's totally outside my field, I can't judge it, so I'm leaving the linking to someone with a clue.

The article looks good to me; I am not a biologist, having taken only college biology courses, but I have some familiarity with the terminology. So if someone else reads the article and thinks it's okay, it's probably worth taking out the notice. Andrew 09:50, Apr 14, 2004 (UTC)

The article is a nice concise overview. I am removing the notice and making a few small edits. E.g, zootomy means cutting up animals; zoology is doubtless intended. alteripse 29 apr 04

This was already pretty good, but I had a further play before checking the talk page - i must stop doing that!! fixed a few links and hopefully clarified and emphasised the main points. the only thing I'm unsure of ist the adipose panniculus, which i've never heard. it'd be great if somebody could check my changes for typos! --Erich gasboy 05:46, 2 May 2004 (UTC)

Pannus and panniculus refer to the "apron" of fat hanging from the abdomen downwards in severe obesity. I am not aware of any difference in the two words and they are used interchangably (although etymologically the one is the diminutive of the other and they are rarely diminutive when worth discussing in a medical context). A large pannus or panniculus complicates surgery of the morbidly obese, and may remain as a literal "apron of skin" if a severely obese person loses most of the excess weight (as after a bypass). Maybe I'll add this to the article. Alteripse 13:29, 2 May 2004 (UTC)


looks good! so what do you do for a day job Alteripse? --Erich gasboy 13:46, 2 May 2004 (UTC) Can't you guess? I teach Latin (and sometimes other things) to our residents. Alteripse 14:31, 2 May 2004 (UTC) ..mmm that makes you an ?old Indianna endrocrinologist??? :-) --Erich gasboy 14:38, 2 May 2004 (UTC) ?old=!ouch but reasonable deducing Alteripse 14:45, 2 May 2004 (UTC) he he. sorry us aussies aren't big on decorum... have you dropped by the Wiki doctors mess? --Erich gasboy 14:53, 2 May 2004 (UTC)

[edit] Should social use include ancient greek sacrifices?

Thanks to Prometheus, the god's portion of a typical Ancient Greek animal sacrifice consisted of bones and internal organs covered with adipose tissue. Perhaps a link should be in the mythology section and not here. I'm not familiar enough with the wiki to attempt an addition, so I'm just commenting here. stevieo@nyc.rr.com

[edit] cellulite

Why does cellulite redirect here? There's nothing in this article about cellulite. -- Kimiko 21:01, 11 Jun 2004 (UTC)

good point. I'll make a stubb ;-) Erich 01:56, 12 Jun 2004 (UTC)

How about adding a stub to the "Adipocyte" entry. Because a tissue is something cpmpletely different than a certain type of cells? --Frosty 21:24, 16 Jun 2004 (UTC)

[edit] Improvement drive

Obesity has been nominated to be improved on Wikipedia:This week's improvement drive. Vote for it there to support the article.--Fenice 20:15, 12 August 2005 (UTC)

[edit] Social and Cultural significance

This section should be exclusively about the social and cultural significance of adipose tissue. Issues about body shape should be (and are) on the obesity page. Zargulon 15:40, 20 September 2005 (UTC)

I don't think this article needs to mention social and cultural significance of adipose tissue. Most people wouldn't even know what it is. JFW | T@lk 16:19, 20 September 2005 (UTC)

I agree. I didn't want to completely rock the boat, since I guess someone put it there for a reason. But I personally would agree with changing the title of that section , or getting rid of it altogether. Zargulon 16:27, 20 September 2005 (UTC)


[edit] Picture

Hi,

On the Dieting page(the exact quote is at the end of this post) it states that body fat has a large amount of carbon mass. I was wondering if it is possible for a picture of the body fat molecules to be drawn, like was done for Hydrogen_peroxide and Lipid?

I did see the molecule picture on triglyceride and lipid, but is there one for regular fat?

"The exhalation of carbon in carbon dioxide comes from carbon mass in the body, a substantial amount of which in turn comes from fat. Essentially the greater part of body fat, the long carbon chains, is lost from the body by breathing."

Bryan 11:15, 24 December 2005 (UTC)

body fats (and vegetable fats) consist mostly of triglycerides. The exact chain lengths are highly variable. Han-Kwang 20:07, 6 June 2006 (UTC)

[edit] Adrenergicand andronergic receptors

From the article:

In humans, lipolysis is controlled though the balanced control of lipolytic B-adrenergic receptors and a2A-andronergic receptor mediated antilioplysis

I think I understand about half of these words. Does this belong in Wikipedia? Han-Kwang 20:07, 6 June 2006 (UTC)

[edit] Growth

So when someone gets fatter do new adipose cells get created or are the old ones growing?--Energman 19:13, 3 January 2007 (UTC)

Mostly the cells enlarge. But mammals turn over their fat cells all the time. Old ones die (by apoptosis) and new ones are formed from precursors - so new cells are being created all the time. I am not aware of a good literature on absolute adipocyte turnover rates although some drugs (thiazolidinediones) seem to have big effects on this process. However the issue in obesity is mostly increased cell volume. S.w.coppack 18:23, 7 August 2007 (UTC)

[edit] Merge proposal

I can't see why these three terms need their own articles; I can't see them being developed much further and they could easily be accommodated within this one (or another more appropriate?) - any thoughts? Madmedea 19:20, 6 January 2007 (UTC)

Merge - I can see them growing to deserve their own articles eventually—especially Visceral fat. But I'd agree for right now, when the three subarticles are just stubs, it makes sense to merge them.David.Throop 22:15, 30 January 2007 (UTC)
No Merge - I vote for allowing the other articles to grow. They are distinct enough physiologically to warrant the independent articles. Intramuscular fat is longer than this article!Mabris 21:35, 1 March 2007 (UTC)

There is an important distinction. Subcutaneous fat and visceral fat are clearly adipose tissue. They should be merged. Intramuscular fat is different. Sometimes, when there is a lot of intramuscular fat, one gets identifiable adipose tissue in the muscle. However in lean animals (and people) there will be just triglyceride stores in the myocytes (muscle cells) plus or minus a few isolated adipocytes between the muscle fibres. Intramuscular fat should not be merged - it should be referenced. Caroline Pond's citation explains all this. S.w.coppack 18:28, 7 August 2007 (UTC)

[edit] Sources for lipid content

I have a few questions about the statement "Human fat tissue contains about 87% lipids." Can anyone point to a scientific source that states that particular number? Also, I am wondering what the remaining 13% are. Enclosed water? Proteins? It would be great if someone could clarify and corroborate that statement. Mirko Raner 23:24, 16 February 2007 (UTC)

[edit] Cells making up Adipose Tissue

This article currently does not mention whether obesity (or excess adipose tissue) is caused by an increased number of adipose cells, or from enlarged adipose cells, or both. It is an important point to clarify in this article. Does anyone have access to a source for this?Mehrshad123 01:40, 14 April 2007 (UTC)

I asked a similar thing in "Growth" above and I got no answer --Energman 14:26, 15 April 2007 (UTC)

Most models of obesity are mostly due to cellular enlargement, although slightly increased numbers are also seen. For example very obese humans might have 10 fold increased fat mass compared to skinny people. Most of this will be from cellular expansion. The adipocyte volumes might increase 4-5 fold, with a 2 fold increase in number. The Cinti reference cited covers this. S.w.coppack 18:17, 7 August 2007 (UTC)

[edit] Merging Visceral fat

No Merge - I think that merging visceral fat article into the main Adipose is a bad idea; there are some important distinctions, and a lot of new research being currently done in this area. More content should be added. 69.209.226.60 20:57, 25 May 2007 (UTC) Caterina Pryde 5/25/07

No Merge - Agreed - viceral fat is being blamed for many medical conditions. Reports in the media suggest that viceral fat cells give off substances that negatively affect the heart and other organs in ways that subcutaneous fat does not. From a public health perspective, I think it deserves to be separate, even if it is just a subset of fatty tissues in general. MarkinBoston 21:43, 26 June 2007 (UTC)

Merge - Agreed. Visceral fat is a sort of adipose tissue. To exclude it suggests that it is not. Until the Adipose tissue topic becomes unweildy, I would include visceral fat. S.w.coppack 18:10, 7 August 2007 (UTC)

I believe this post was intend to be a vote for merging. Based on the content his/her post, I believe S.w.coppack intended to agreed with merging, rather that the post above him/her. I am placing a bold merge/no merge in from of each post for clarity.Bpage 08:46, 21 September 2007 (UTC)

Merge - I think both visceral fat and subcutaneous fat should be merged here. They are types of adipose tissue. None of the three articles are particularly long. Merging them would result in a more clear understand of any of the three subjects.Bpage 08:46, 21 September 2007 (UTC)

[edit] Human Examples

Another comment. I think readers are more interested in the distribution of Adipose Tissue in Humans rather than in Mice. [E. A.] 16 August 2007

[edit] Request: How many usable Joules per kilogram of fat? Same as food energy amount?

How efficient is the human body in storing energy? How much is effectively used after storing and re-burning? --Sigmundur (talk) 20:36, 5 June 2008 (UTC)
