Calories is the unit to measure heat, where as Fat in terms of Chemistry is long chain molecules of fatty acids due to which Fat is solid at lower temperatures. \nIn common language calories is used to tell the amount of heat we can get from a specific food, and fat is the extra calories which are stored in body.

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.

The nutrition books are correct-- 3500 calories per pound of fat is not an absolute amount, but it's very close. However, your math is correct, too. Here is the story. \n\nWhen we burn fat, or other nutrients, heat is produced, which is measured in calories. As you note, each gram of fat generates 9 calories, and 454 grams equals one pound. But a pound of fat is not all fat. It's about 10% water. All of our body tissues--fat, muscle, bone, skin--contain some water. And water has zero calories.

You would only see fat on your body if your daily intake of calories was more than you used in activity. Also, this ratio has to occur over time, like a week. If you eat a Snicker bar tonight and nothing all day you will not get fat. If you eat 3,000 calories today AND  Snicker bar tonight you WILL  get fat. It's that simple. Fat is created from excess calories.

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.

You can't lose one pound of fat in a day. It takes 3500 calories to gain or lose a pound of fat. That is why it is a good idea to try to lose only 500 calories a day. That way, in one week, you will lose one pound. This way, you can eat healthy and still lose weight. It's all about eating right and exercising. There is no magic pill. It takes time and effort.

1 calorie is the amount of energy it takes to heat one litre of water by one degrees celsius.  But it is useful for measuring the energy in food.  Women can have 2000 cals a day and men 2500 to maintain their weight.  So women can wat (7*2000) 14000 cals a week.  1lb of fat stores the equivalent of 3000 cals, so by decreasing your intake of cals by 3000 a week you would lose 1lb a week.  Any diet that decreases the amount of calories you eat will make you lose weight.  But healthy goods are naturally low in calories and are more nutritious.  So eating healthy food (not white breads) will make it easier for you to lose weight and stay healthy.  If you are going on a diet for a long time take a multivitamin. Exercise can be simple, take the stairs, get off the bus a stop earlier than you have to etc... But the author of the GI diet correctly says its much easier to lose weight by dieting than exercising.  To lose 1lb exercising a week you would need to briskly walk for 9 hours a week!

Sugar causes the body to produce insulin and this leads to the storage of excess calories as fat.  Sodium doesn't have much to do with fat at all.

Body fat includes all fat stored in the fat cells and  organs of the body and includes both essential and non-essential fat stores.

Burning fat is all about using up more calories than you take in. If you eat more calories than your body uses throughout the day, these additional calories will be stored as body fat. To prevent a build up of body fat you need to either reduce your calorie intake or increase your daily activity levels - doing both will have the best effect on reducing body fat. The more fat you want to lose then the greater the amount of calories you have to burn off. This means exercise!. Regular workouts, tied with a healthy balanced diet is the best way to work off that fat, and get a new slim shape.

You have to be careful about what you mean by calorie, as there are two kinds.  The standard calorie (the energy it takes to raise 1 cc of water 1ºC) is 4.185 joules.  However the calorie used to depict the energy content of food is the "large Calorie", spelled with a capital "C",  and is equal to one kilocalorie and therefore 4.185 kilojoules.

I don't think there's any difference between kcal and cal.

A pound of fat is 3,500 calories in excess of the calories your body burns. You can calculate your basal metabolic rate (the minimum number of calories your body burns just being alive every day) and then using a tool like Fit Day online to calculate how many calories you're expending with your life style and working out. Compare that to the number of calories you eat every day.  The chances are--if you're working out and not eating excessively, your weight gain is probably mostly muscle. \n\nThere are scales you can buy that approximate fat and muscle composition, but the only way to find out for sure is to get doctor's measurements like underwater weight testing (fat floats while muscle doesnt).  If you don't want to pay money for things like that and just want to be healthy--take repeated tape measurements of your chest, waist and other body parts. The location of inch decreases/increases will tell you where the weight is going. You may be losing fat while gain muscle mass.

A calorie is a calorie. 3500 calories, regardless of where it comes from (fat/carbs/protein/alcohol), can create 1 lb of fat. Current diet recommendations specify a percentage of calories from fat, typically 20-30% of your daily food. Problem is, 1 gram of fat provides 9 calories, whereas 1 gram of carbohydrates or protein is only 4. So....an equal amount of fat will have more than twice as many calories than an equal amount of carb/prot.\n\nThe calories from fat is just a way for you to see how much of the food is fat. However, they simply list how many calories come from fat - the rest from prot/carbs. A "better" way (and companies won't do this) is to simply divide the fat calories by total calories, so you can see what the % is (you can do this yourself of course). Then, when you see that a hotdog is 90% fat and you are trying to hit 20-30% per day, you might think twice!\n\nJohn

sure can.  Especially if you eat more of one and not the other.\n\nBut seriously,  There are good calories and there are bad calories.  I recommend getting to know the good ones by getting some books on the subject of nutrition.  Learn the difference between the calories that your body can turn into energy, and the kind that just get stored as fat.\n\nFat is the result of your body storing up for energy when you need it later.  Usually a result of an improper diet.\n\nIf you eat a lot of sugar, your body gets used to the quick energy and fails to use the fat calories in foods, so it gets stored up.\n\nIf you do not eat a lot of sugars,  then your body will use the FAT as energy instead.\n\nSo your body will determine which foods will be "more fattening" depending on your normal eating habits.
