Question 1

how does brown fat differ from the other fat in your baby?

Accepted Answer

More heat!: Brown fat, which develops in babies during the 3rd trimester, is very important helping the  newborn maintain a stable temperature. Premies do not have time to develop brown fat, and they often have trouble maintaining a normal body temperature.

Question 2

is there such a thing as baby fat in newborns?  i've heard of brown fat that animals burn to generate warmth.

Accepted Answer

Brown fast: Full term babies have brown fat which is needed to produce hit.

Question 3

when cold, does the body use stored brown fat as an insulator, or does it actually burn the fat for warmth?

Accepted Answer

Almost neither: Official "brown fat" is only present in newborn babies as a source of immediate energy.  As we age, this turns to regular yellow fat as you know it. In order to produce heat, there are more immediate sources of energy that the body draws on than fat.  Even over the long haul, i don't believe that stored fat would be used much for energy needs unless circumstances were extreme and nutrition scarce.

Question 4

what makes brown fat look brown, and red muscle cells look red? is it mitochondria, iron, or something else?

Accepted Answer

Lets review your que: Brown fat contains high amounts of smaller sized "fat droplets which are iron-rich mitochondria giving it its brown color. brown fat also needsmore oxygen so has many capillaries suppling oxygen to the tissue.
Red muscle also known as slow-twitch muscle fibers are rich in mitochondria and myoglobulin giving it its red color. Since it is also oxygen rich many capillaries carry in oxygenated blood t

Question 5

can the human body still burn fat if it does not have "brown fat" (brown adipose tissue)?

Accepted Answer

Yes, but...: As far as i know, everyone has brown fat, though some people have more than others. While brown fat burns fat, it is definitely not the only way our body burns fat. See http://www.Medicalnewstoday.Com/articles/240989.Php.

Question 6

orexin is needed to produce brown fat which burns fat.so people with narcolepsy have orexin deficiency , so can people with narcolepsy still burn fat?

Accepted Answer

Yes: Great question! yes, people w/narcolepsy can still burn fat. It's just that it's more difficult to get physically active when one can't get a good night's rest.

Question 7

my pet-ct scan for hotpshkins lymphoma came up with increased metabolic activity around brown fat in base of neck, should i be concerned?

Accepted Answer

No: Brown fat is metabolically active in order generates heat, and for this reason more likely to be active during the winter months.  Since brown fat uses more glucose than normal fat, it lights up on a FDG pet. Correlation of pet images with the ct portion of the exam can easily identify the active regions as fat rather than lymph nodes or tumor.  Typical location is around the clavicles.

Question 8

ct pet brown fat in neck/ mediastinum near small lymph node difficult to know if node hypermetabolic  suv low in node not enlarged. significance?

Accepted Answer

Ultrasound neck: Lymph node  small size usually mitigates against neoplasm. An easy way of following lymph node would be ultrasound in a month to see if node enlarges or is stable in size. Tumors usually grow with time.

Question 9

hi i'm a 28. year old female. in had banding of hemmoriod s twice i'm always losing thick brown bloody with white swirls in i don't.even have.to hav. ?

Accepted Answer

Question is not clear: your question is not clear. Anyway having a blood or swirls or white discharge after hemorrhoid banding you need to contact to consult with the G.I. doctor or surgeon who did the hemorrhoid banding. If you're having pain fever chills or significant bleeding get immediate medical attention .

Question 10

how do you lose fat?

Accepted Answer

Less in, more out.: It's a simple law of energy intake and expenditure. To lose fat, you not only have to simply cut calories in diet but also increase energy expenditure by exercise (both cardiovascular and strength training).
