The energy contained in food, measured in kilocalories, often described simply as calories.
The amount of heat needed to raise the temperature of one gram of water from 14.5°C to 15.5°C when the water is at atmospheric pressure.
A calorie is a unit of heat content or energy.
A unit of measurement of heat. The amount of heat needed to raise the temperature of water from 14.5 C to 15.5 C.
The more common unit of measure used for the amount of energy produced when food is oxidized (burned).
units representing the amount of energy provided by food. Carbohydrates, protein and fat are the primary sources of calories in the diet, but alcohol also provides calories. If all calories consumed aren't used as energy, they may be stored as fat.
Units of measurement that represent the amount of energy the body is able to get from foods. Different nutrients in foods provide different amounts of calories. Carbohydrates and protein provide about 4 calories per gram, while fat (bother saturated and unsaturated) yields about 9 calories per gram.
Measure of energy value of food.
A unit of measurement for the amount of energy that is released from food upon oxidation by the body. Also the amount of heat required to raise the temperature of 1 kilogram of water by 1°C at 1 atmosphere pressure.
are the units used to measure the amount of energy supplied by food and the amount of energy burned by activity.
Measurement of the potential of food to supply energy. Carbohydrates – The body's principal source of energy. Simple carbohydrates come from sugars; complex carbohydrates come from starches and fiber. The body converts them to glucose, which is used to energize cells.
The body's energy expenditure is measured in calories. Consider that 1 lbs of body fat stores 3500 calories. Let's say you want to lose 1 lbs of body fat and you burn 2000 calories/day. To lose one pound of body fat per week you need to eat 500 calories less per day than your body needs.
The unit of measure used to refer to the amount of energy produced when food is oxidized (burned).
A measure of the energy in food.
Units by which energy is measured. One calorie is equal to the amount of heat necessary to raise the temperature of 1 kg of water 1 degree C.
Energy is usually measured in calories. Basically it's a quantity of food capable of producing a certain amount of energy. It's measured in terms of heat. Also called kilocalorie or large calorie.
units that measure the amount of energy the body is able to get from food. Different nutrients in foods provide different amounts of calories.1
the measure of the energies supplied by the food we eat.
A unit of energy content in food. CF patients require foods high in calories or energy content.
