Talk:Fat
From Academic Kids
Huh? The human body burns fats to supply the energy to contract and relax muscles (whereas the electrical energy needed for neural activity is provided by burning carbohydrates). Unfortunately what seems to have been overlooked, is that humans come in two types with two types of 'engine'. Those with an 'engine' which can burn either type of fat and those whose 'engine' is tuned to run at its most efficient on animal fat alone. How do you tell which type of 'engine' your body has? If you have the former, you get an equal pleasure response when you eat either butter (an animal fat) or margarine (a vegatable oil) and if you are the later you prefer the taste of butter. There is an actual difference in physical response too. The former salivate over the taste of either fat and the later only salivate over the taste of animal fat. Because the latter type run on animal fat and animals come in two types, diurnal and nocturnal, this has led to all the weight problems. People who have weight problems prefer the taste of animal fats and have been advised to eat the lower caloried vegetable fats because they have put on weight when they ate the food they preferred. That was the wrong answer! They two fall into two catagories, diurnal and nocturnal. To find out which, simply ask them when they would prefer to go out for a special meal, lunchtime or in the evening for dinner. Diurnals choose lunch and should never eat after dark and nocturnals choose evening and should only eat after dark. Were they to only eat the food the like at those times of day, they have as perfect a 'built-in' weight control system as any of the former type with the bodies tuned to run on either type of fat, i.e. thin people.
That sounds like a crackpot theory from some weight-loss author; do you have any evidence that this is actually accepted by real biochemists? --LDC
I let it remain on the page because i had never heard of _that_ strange theory before, and there are a couple of actual factoids in it...I'll extract them and add to the article. --Anders Törlind
Animal fat and vegetable fat. Where do you put fats stored by other sorts of living things - fungi and protozoa?
- Is there a chemical difference between these types of fat?
- "Vegetable fats were developed by plants as a means of attracting animals..."
This seems to imply some kind of motive to plants. -- RTC 20:26 Apr 8, 2003 (UTC)
Vegetable fats are developed by plants as a means of attracting animals in need of energy, in order to spread seeds or further pollination.
I disagree with this. and agree with RTC. This comment sounds very very weird to me. ant

Carbon in fat?
Does fat contain carbon atoms? Brutulf 16:20, Nov 19, 2004 (UTC)
- Almost everything found in the human body contains a carbon atom somewhere. In particular, yes, fat contains carbon. In fact, the distinguishing feature of fatty acids is how many of it's carbon atoms are saturated with hydrogen atoms. Kutulu 12:09, 26 Apr 2005 (UTC)
Whats up with these unit conversions? They're off by 1000 fold.
"Fat is one of the three main classes of food and, at approximately 38 kJ (9 Cal) per gram, as compared to sugar with 17 kJ (4 Cal) per gram or ethanol with 29 kJ (7 Cal) per gram, the most concentrated form of metabolic energy available to humans."
Cal = calorie correct? and KJ = kilojoule correct?
If so those calorie numbers are missing a 1000x multiplier.
Google for "convert 38 kilojoule to calorie":
38 kiloJoule = 9 082.21797 calorie
Obviously wrong
Those values were obviously wrong, yes. So why didn't you just correct them? Be bold! :)Brutulf 22:36, Mar 21, 2005 (UTC)
Edit: Upon closer examination, it seems that there are two ways of writing it, either as kilocalories or just calories (I would prefer kilocalories). Confusing, eh? See calorie. Brutulf 22:49, Mar 21, 2005 (UTC)
Admins, quick revert needed
Someone vandalized this. Quick revert needed ASAP! --Dungodung 18:13, 5 Jun 2005 (UTC)
