Fat has virtues too!
-
fatty takes up more space on the trains..
but nice to play with esp when we are young,cause they can't chase after u.. -
ur sentence sentence is mean...hahha, but true leh...play catching they can't catch u then end up u just need to run abit wait for them then start to run u already run liao cos htey got higher inertia to overcomeOriginally posted by stellazio:fatty takes up more space on the trains..

stop hitting me..
i know u know i cant catch u
poor piggys.. -
u can catch them....u need to apply heat transfer equation again, either by increasing Ein and Egen and/or decreasing Estorage...with higher Eout u can use the energy to run fasterOriginally posted by SGpork:stop hitting me..

Very fanciful explanation.Originally posted by chunyong:this can be explained using heat transfer equation
BUT, it still does not address the glaring issue of fatter people feeling colder than the thinner ones!
THis hypothesis totally ignores that occurence! -
Folks, this thread is not meant to be a thread to insult fat or thin people, ok!
It's a thread to discuss DIETARY fat.

i explain why skinnies cannot feel warmer than fatsos niah...pls do not misinterpret hor...hahahaOriginally posted by Rhonda:Very fanciful explanation.

why do fat people feel cold, rhonda asked for explanation so let me explain once again using the same heat transfer equation.
From my previous reply, we ignored conduction and radiation, which forms part of the Eout portion. We did not take into account heat loss by convection. With reference to my previous reply, the following can be understooded
Heat rate Qconv = hA(Ts-Ta)
Ts = Body surface temp
Ta = Ambiance temp
h = coeff, which is the same since all humans
A = surface area
Since h, Ts, Ta remains the same for both fatso and skinny, we look at A. fatso's A is higher, hence heat loss by convection will be higher. Since Qconv is part of Eout, Eout will go up, causing Estorage to be lower. Hence, this explains why fatsos feel colder. -
Off-topic for a wee bit...what else can I coat sausages to be grilled or BBQed with apart from butter? Olive oil? Rapeseed oil? Sunflower oil? Or how about canola oil?

olive and canola oil more healthy but butter taste nicer lah...see which side takes ocntrol, the health conscious side or the tastebuds sideOriginally posted by Kuali Baba:Off-topic for a wee bit...what else can I coat sausages to be grilled or BBQed with apart from butter?

Fats can keep us warm also.Originally posted by Rhonda:This thread is gonna make some of you flip or see red! 
And yup, this is an info-thread supposed to be 'in defence' of fat!
Read this and thought it was interesting :
"As nutritionists know, fat is a vital nutrient. Like carbohydrates and protein, dietary fat is an important source of energy for the body. In fact, fat is the most concentrated source of energy in the diet, providing 9 calories per gram, as compared with 4 calories per gram from eithe rcarbohydrates or protein.
"Dietary fat supplies essential fatty acids, such as linoleic acid, which is especially important for young children's proper growth. Fat is also required for the maintenance of healthy skin, regulation of cholesterol metabolism, and as a precursor of prostaglandins, the hormone-like substances that regulate some body processes.
"An excess of fat in the diet, however, is increasingly being recognised as a risk facotr influencing the development of several chronic diseases.
From : "The Great Food Almanac : A Feast of Facts from A-Z", Irena Chalmers.
Interesting, right? See, you can't eradicate fat from your diet entirely!

Ah yes, I want it to taste as good as possibly...and the oil has to withstand the heat of grilling.Originally posted by chunyong:olive and canola oil more healthy but butter taste nicer lah...see which side takes ocntrol, the health conscious side or the tastebuds side -
butter liao lor...smell nice, taste nice and easy to apply...Originally posted by Kuali Baba:Ah yes, I want it to taste as good as possibly...and the oil has to withstand the heat of grilling. -
No, I want a healthier alternative that tastes as good.Originally posted by chunyong:butter liao lor...smell nice, taste nice and easy to apply... -
I'm merely pointing out the shortcomings of your explanation... please do not shirk the issue, hor!Originally posted by chunyong:i explain why skinnies cannot feel warmer than fatsos niah...pls do not misinterpret hor...hahaha -

So, with this new 'theory' of yours, you have completely negated and disproved your previous 'theory'?? -
Originally posted by chunyong:olive and canola oil more healthy but butter taste nicer lah...see which side takes ocntrol, the health conscious side or the tastebuds side True! That's the eternal debate - healthy or delicious?

If there can ever be tasty and healthier equivalents to sinful food, there wouldn't be any overweight and obese people around, neither would there be any high-cholesterol problems, would there?Originally posted by Kuali Baba:No, I want a healthier alternative that tastes as good. -

the heat transfer coefficient, h, is not the same for hairy and hairless humans with the latter having a higher value, thus hairless humans loses heat faster by natural convection.Originally posted by chunyong:why do fat people feel cold, rhonda asked for explanation so let me explain once again using the same heat transfer equation.

the formula for Qconv is for heat transfer between the topmost layer of the skin to the environment. we have to consider how does heat gets propagated from inner body to the topmost layer of the skin. this is significant here becos a fat person generally have more and bigger fat cells. fat cells besides containing fat, they consists mostly water. since water has a high specific heat capacity, it retains heat well. therefore, a fat person can "trap" heat better than a thin person under the assumption that both have the same metabolism. consequently, when they are under a hot sun, the fat person is less efficient in dissipating heat than the thin person, and hence will feel hotter. -
bout the same thing lah...Originally posted by Rhonda:Is bak bak = bwee bwee -
Ein is dependent on the surface area of a person, thus a fat person will have a higher Ein than a thin person. Eout is NOT negligble because if it is indeed true, we will die from heat stroke (either when exposed to the hot sun or by our body internal heat generation as a byproduct of the respiration cycle)Originally posted by chunyong:this can be explained using heat transfer equation
Ein+Egen = Eout+Estorage - (1)
re-arranging equation (1), we get
Ein+Egen-Eout = Estorage - (2)
Since we all are exposed to the same environment, Ein remains the same so we can't compare it. The warmth one feels is Estorage, after taking into account of the body's heat loss (Eout) to the environment via radiation to the surrounding surfaces and conduction to the ground. We assume conduction tends to zero as we take the shoes as an insulated surface. Heat loss via radiation we take it to be negligible as well. So we are left with Egen, which correspond to the amount of 'energy stored' being utilised, in simpler terms, FATS. Hence from equation (2), we derive;
Egen = Estorage.
Therefore, fatsos will feel warmer than skinny fella.
in fact, one of the major reasons why human is superior than other mammals (other than intelligence) is that we have one of the most efficient heat loss (that is, Eout) than other mammals. -
the sensation of hot and cold felt by a person depends on many factors. among them, the 3 most significant ones are: 1) sensitivity of our nerves 2) metabolism 3) efficiency of digestion system
1) hot and cold sensation does not necessary equate to more and less heat in our body respectively. our body is not an accurate thermometer and each of us are calibrated differently becos we have different number of nerves cells with each sensitivity. i do not know of any reports that state that fat people have different sensitivity or quantity of nerve cells than thin people.
2) & 3) a thin person does not necessarily have high metabolism, and likewise, a fat person does not necessarily have low metabolism.
case (a) a thin person can have low metabolism by having a poor digestive system. so this type of person will not feel hot all the time.
case (b) a thin person that has high metabolism, he/she will feel hot and react faster to cold temperatures.
case (c) a fat person can have high metabolism by having an efficient digestive system, provided the digestive system is more efficient than the high metabolic rate. he/she will also react well to cold temperature.
case (d) a fat person who has low metabolism will not react well to cold temperature.
these 4 cases illustrate that the physical size of an individual is not an accurate way to predict his/her reaction to cold temperature.
also, a muscular person will also feel hot becos to maintain the muscles, it heats to burn lots of fuel (that is glucose), which generates heat. if you want to be more resistant to cold climates, builld up your muscles. this works no matter u are fat, thin, low/high metabolic rate, efficient or inefficient digestive system.

I eat fat every day - Omega 3 oil and lecithin capsules. Yum yum, brain food.
