We need energy to live our everyday lives.
We gain our energy from foods to support minimum calories each day. This is our (BMR)
Energy is measured joules/calories, these are times by 1000 and
Energy is measured in calories or joules. As both these units are small they are multiplied by 1000 and mentioned to as minor units of heat or kilojoules.

Skin fold analyses is measuring body fat, finding your right body weight and composition. Underneath the skin there is a layer of hypodermal fat, the percentage body fat can be measured by taking the skinfold test at a particular point on the body with a pair of callipers.

The indirect calorimetry

There are four main components to energy production which are:
Resting metabolic rate is a quantity of food or energy is essential to uphold basic body functions such as breathing, heartbeat and care of the body heat while you are at rest. (RMR)
Dietary thermogenesis talks about the energy expended above the RMR for the procedures of digestion, concentration, transport and loading of

    Energy metabolism is generally defined as “The entirety of an organism 's chemical processes. These chemical processes typically take the form of complex metabolic pathways within the cell, generally categorized as being either catabolic or anabolic. In humans, the study of how energy flows and is processed in the body is termed bioenergetics, and is principally concerned with how macromolecules such as fats, proteins, and carbohydrates break down to provide usable energy for growth, repair, and physical activity.” (Gore, 2014)…

    -Supplying enough energy to support the many functions of the body at work and play is one of the main functions of food. This energy comes from the fats, carbohydrates, and proteins in the food you eat. Of the three, fat is the most concentrated source of energy because it furnishes more than twice as much energy for a given weight as protein or carbohydrate. The energy requirement for a person is divided into two parts: basal metabolic requirements and energy required for activity. Basal metabolic rate is the heat eliminated from the body at rest when temperature is normal. An average person requires 2000-2400 Calories per day while a large man doing heavy work may require up to 6000 Calories per day.…

    Most of the processes taking place inside our cells need energy in order to happen. Depending on our age, weight, the activities we will need a certain amount of calories. If somebody run every morning, will require more energy and calories per day. If somebody are an athlete also will require more calories per day. If the person sit, and work on a computer all day then that person don’t need many calories per day. Energy is measured in kilojoules (kJ).…

    Metabolism is the chemical reactions in which an organism utilizes energy to maintain life. Since glucose is a main source of energy, organisms use glucose along with oxygen to produce carbon dioxide, water and heat (Randall et al; 2002). Knowing this, metabolism can be measured by the production of CO2 or the consumption of O2. This is called indirect calorimetry (Randall et al;…
