How are the amount of calories measured in food? i.e. 1 slice of cheese = 60 calories (how is the 60 derived?)

The calorie we see on food is really the kilocalorie.\n\nA kilocalorie is the amount of energy needed to increase the temperature of 1 kilogram of water by 1 degree Celsius under Standard Temperature and Pressure.

Calories are energy, essentially. In fact, they're also a unit of measure of energy. \n\nThe human body only needs a certain amount of calories to carry out life processes and fuel the body. When you consume in excess, the calories are stored as fat and other unhealthy compounds.

I'm not sure I agree with the 100 cal = 1 kcal.  That would mean that your mustard, at 57 kcal is actually 5700 calories.  That's an awful lot of mustard, somewhere on the order of 7 pounds if you work out the math (I used the Harrods traditional English mustard label for reference).  Anyway, kcal in UK and Ireland and many other European nations are the equiavalent to calories as measured here in the USA.  kCal is actually the more correct measure, scientifically speaking, however for some reason we adopted the standard "calories" here.  As for why the descrepency between British and American products, that's hard to explain.  My only guess is that the British one is being measured against 100g of product (typical practice), while the US version is measured for a teaspoon.  In that case, the calories in a tsp are quite low, maybe not zero, but low.

It's ok we all need reasurance sometimes.  it seems like you work hard but just got confused.  I'll try and help.\n\nI’ll assume you know how many pounds is lost given a certain amount of calories because I don’t.  If the desired weight is 5 pounds take the number of pounds lost per calorie and multiply it by 5..  This number is the total amount of calories needed to burn.  Then you take that number and you divide it by the number of calories burnt in an hour (740) That gives you the number of hours.\n\nI'm an economist not a nutrition major so sorry hope the suggestion helps.  It seems like your other answerers are too harsh.

I think this is about asking people to rate things on a scale, for example "How much do you like eating cheese? rate this on a scale of 1-10 where 1 means "I hate cheese, I wouldn't eat it if you paid me twice my annual salary" and 10 means "I love cheese, I want to eat it all day."" Irrespective of what they actually think, most people will opt for a number roughly in the middle of the scale, so you will get lots of 5's and 6's and very few 1's or 10's. this means the results from this kind of question may not be accurate.

They literally burn the food in a special device and measure the heat energy given off.  The original heat energy used to burn the food sample is subtracted and the difference is the caloric content of the food.

Energy comes in a variety of forms: light, heat, motion, electricity, and so forth. The energy in food is measured in units of Calories. A Calorie is defined as the quantity of heat it takes to raise the temperature of 1 kg of water 1 degree Celsius. The energy in food is defined in terms of heat because the quantity measured is heat produced upon burning the food. Burning in the presence of oxygen is the process of combustion. Complete combustion results in the production of energy as well as carbon dioxide and water. Look for evidence of these products during your discovery session.\n\n\nFood often is labeled with the number of available Calories per gram of food. In this discovery session, you will measure the amount of energy in Calories in two types of nuts: peanuts and almonds. The accepted values for these nuts are listed in many Calorie-counting and diet books (5.18 Cal/gram for peanuts and 5.47 Cal/gram for almonds). This energy is converted into a usable form by chemical reactions in the human body. Therefore, the number of equivalent Calories of food that you eat gives an indication of the amount of energy you will have at your disposal.\n\nQUESTION: How are calories measured? \n\n\n\nANSWER: The caloric value of food is the energy produced by combustion of its proteins, carbohydrates and fats. The amount of energy liberated by the catabolism of food in the body is almost the same as the amount liberated when food is burnt outside the body. The energy liberated by catabolic processes is used for maintaining body functions namely digestion, thermoregulation, muscular contraction and nerve impulses conduction. The amount of energy liberated / unit time is the metabolic rate. When food is burnt outside the body, all the energy is liberated as heat. \n\nThe standard unit of heat energy is the calorie (cal), which is defined as the amount of heat energy necessary to raise the temperature of 1 ml of water by one degree, from 15 to 16 celsius at rest. \n\nA slightly different calorie is used in engineering, the international calorie, which equals 1/860 international watt-hour (4.1868 J). A large calorie, or kilocalorie, usually referred to simply as a calorie and sometimes as a kilogram calorie, equals 1,000 calories and is the unit used to express the energy-producing value of food in the calculation of diets. \n\nThe energy released by combustion of foodstuffs outside the body can be measured directly and indirectly. In direct calorimetry method the liberated energy can be measured using a bomb calorimeter. It is a metal vessel surrounded by a water insulated container. The food is ignited by an electric spark. The change in the temperature of water is a measure of the calories produced. \n\nIn indirect method, the energy production can also be calculated by measuring the amount of oxygen consumed for combustion of food. The amount of oxygen consumed / unit of time is proportionate to the energy liberated. This method of energy estimation is called wet combustion. The caloric value of carbohydrate is 4.1 Kcal /g, protein is 5.65 Kcal/ g and fat is 9.4 Kcal/g.

Your question is poorly worded but I think the answer you are looking for is one calorie.

calories r units of energy like metre for distance...\nso they r just arbitary and cant b seen under microscope...

The easiest way to determine how many calories you can eat and lose weight is by figuiring out how many calories you burn a day.  As long as you burn more than you eat, you'll lose weight.

The 2000 calorie FDA label is total calories.\n\nCalories from fat should already be included in the total calorie heading.  If you're on a 1000 calorie diet for whatever reason (not really recommended but it's your choice), then you count the total calories for each food.\n\nThe calories from fat are just part of the breakdown.  There are also the calories from carbs and protein.

I just ate THREE philadelphia cream cheese fat free tubs in 3 days and you know what!!?? the WHOLE TUB has 210 calories!!!!!!!!!!!!!! and it was shared with roommate equally so I was only having like 105 calories for half!!!!!!!!!!!!!!!!!!!!   I ate it with carrots or on light bread which is 40 calories a slice!!!!!!!!!!!!!!  can u get any lower?

The number of calories *is* the total number of calories.  Calories only come from protein, fat, or carbs.  So listing the "calories from fat" is just telling you the fat calories.  If you add up the number of calories from protein, fat, and carbs, you should get the total number of calories- the number on the label after "calories."\n\nPcal + Fcal + Ccal = Total Calories.\n\nSo yes, that first calorie reading is what is contributing to your total calorie intake.  The rest just tell you what the calories consist of.
