Energy is measured in four different categories; calories, joules, kilocalories and kilojoules.
Calories are the energy required to raise the temperature of 1 gram of water by one degree.
A joule of energy is what it takes to move a mass of 1 gram at a velocity of one meter per second. For every one calorie there are 4.2 joules. A kilocalorie is the amount of energy to raise 1 kilogram of water by 1 degree. Kilojoules is the same a joules but it needs to be times by one thousand.
The body needs energy to function. We get energy from carbohydrates, fats and proteins.
For every 1 gram of carbohydrates it will get 4 kilocalories (kcals) or 17 kilojoules (kJ). For every 1 gram of Protein it will get 4 kilocalories (kcals) or 17 kilojoules (kJ). …show more content…
Carbohydrates are the bodies most readable source of energy as it can be easily be accessed by the body, but the body can only hold 500 grams of carbohydrates which amounts to 2000kcals.
Proteins are used for growth and repair rather than an energy source. However on rare occasions where the fats and carbohydrates have been used the body will convert the protein in to energy. Protein is split into two groups; these are called complete and incomplete. Complete proteins are foods will contain all of the essential amino acids whereas the incomplete will be lacking all the essential amino acids. The 8 essential amino acids that cannot be made by the body so the body relies on the food intake to bring them into the body. Some examples of foods that contain amino acids are known to be Fish, Eggs and dairy, Sea vegetables.
Fat is used when there are no or little carbohydrates left to be used for energy. However fats are mainly used for low intensity works outs. They are the largest potential energy store as the body can hold a lot of it, but if the fats aren’t used then it can stored which can lead to weight gain if excess are eaten. You can get 9 calories per gram of
