Fat cell metabolism

[LisaS]

Although I have not finished it, I am finding this article very interesting. It primarily deals with adipocyte metabolism, visceral fat compared to subcutaneous fat & implications for carbohydrate consumption.

I remember this review. It came out a few months after the Kingsbrook Conference on the Metabolic Effects of Low Carb diets. I distinctively remember it because I had a discussion with one of the speakers about a previous article showint that visceral fat didn't contribute with fatty acids as much as it's been thought and it was indeed subcutatnous fat what provided more FAs. And this review seems to still hold to that. It'll make a good reading again! Thanks for the link Lisa! It gave me the chance to save the file this time... I still have a lot of stuff in a box and who knows where the hard copy of this paper is.

I'd love to discuss some (or all) of this as I just finished my 'time' working on the field of fat cell metabolism.

Is there any link/site that I could use for a biochemistry "term" reference/definition for the average person? I'd really like to understand some of the terminology used that currently is over my head.:rolleyes: :(

I have used wikipedia for subjects I'm not familiar with. It does have a discussion on fat metabolism I understood but I'm not sure of the accuracy of the facts and science.

Thanks DJK, that's a great source! Thanks!

A word of caution about wikipedia... some of the information may not be accurate at all and there is no way to predict in which topics this is the case. The problem seems to be that there's not enough 'fact checking'. I've found (and heard from others) mistakes that are hard to catch if you're not in the particular field.

Amazingly, the 'prestigious' journal Nature placed wikipedia at the same level of Enclyclopdia Britannica, which of coruse for the Britannica that was nothing but an insult. You can read about their rebuttal to Nature here (http://news.bbc.co.uk/1/hi/technology/4840340.stm), read the actual letter here (http://72.14.207.104/search?q=cache:aLJ-DSjZ1zoJ:corporate.britannica.com/britannica_nature_response.pdf+Fatally+Flawed&hl=en&gl=us&ct=clnk&cd=1&client=firefox-a)(html) or print the pdf file here (http://corporate.britannica.com/britannica_nature_response.pdf).

Just so you know :)

Just be forewarned Gabe...lol I'm not opposed to making up my OWN vocabulary!:D

Example:

Visceral adipose tissue = annoying floppy overhang belly! :rolleyes:

My "particular field" is definitely solidly in the LEFT one! lol :D :rolleyes:

It would just be soooooo much more simplier if everyone spoke MY LANGUAGE! lol But, although I can't promise anything...I'll do my BEST to step up to yours! :)

I printed off this link to take this weekend while we camp. :eek: I'm sure I'll have questions, but I'll try not to bug you. lol

I'm sorta glad you were "away" for awhile...lol...it gave my brain cells a chance to chill out! lol :eek:

actually, your definition for VAT is just off the mark enough to miss some of the points of the article. visceral fat is fat under the muscle layer actually inside the belly - so it is around the internal organs, around the intestines, etc. Subcutanous fat sits under the skin.

so in the article starts off with:

VAT depots, located in the body cavity beneath the abdominal muscles, are composed of the greater and lesser omentum (peritoneum that is attached to the stomach and links it with other abdominal organs) and the mesenteric fat. A lesser amount of VAT is located retroperitoneally. In general, VAT accounts for up to 20 percent of total fat in men and 5–8 percent in women. The abdominal SCAT is located immediately beneath the skin and on top of the abdominal musculature. The predominance of lower body fat is SCAT, most of which is stored in the femoral and gluteal regions [3-5]. Abdominal obesity can reflect a predominance of flabby SCAT; a firm, only modestly enlarged waist line resulting from deep VAT pushing the abdominal musculature outward; or a combination of enlarged SCAT and VAT depots.


it is saying - you can be fat under the muscle around the organs (VAT) or you can be fat between the skin & muscle (SCAT). Most of your lower body SCAT will be in your hips, butt & legs. If you have a larger waistline, it could be firm internal fat (VAT) only making your belt go up a little bit or it could be flabby external (SCAT) or both. These two different kinds of fat seem to act differently - and that is what the article mostly covers.

Gabe is absolutly right. Always check your facts. "Trust but verify" I personally only use it as a starting point if I want info on an unfamiliar topic. Can usually dig deeper by checking some more reliable sources.

Lisa! I SEE what you mean!!!! :rolleyes: Fat is not just fat is it? I printed out and read that article over the weekend. I've made a list of words I need to look up and then I might have questions!?

DJK, I will use it wikipedia just to get myself more familiar with terms but ask questions here, so thanks for that.

So, it's more important for your VAT fat to scat than it is for your SCAT fat to do that?

[joanneb608]

You're a POET and you DO know it!!:D:D:nod:

Yes it sounds to me that getting rid of the VAT fat is probably the best thing your body could do for itself, healthwise, like it helps your internal organs to function more efficiently.

Now if the SCAT fat below the waist will just SCAT:cool:. OK I'm done now.
