Metabolism is defined as a series of chemical processes that transform food into oxygen and energy products necessary to sustain life. One way to understand metabolism is to follow typical nutrients as they travel through the body. The breakdown products of the foods you eat – glucose, carbohydrates, amino acids, protein, fatty acids and fat – are part of the drink that activates the hormone insulin and activates the body’s food energy machine.

Energy comes from the macronutrients (carbohydrates, fat and protein) found in food. Carbohydrates, fats and proteins provide our body with energy from the food we eat. The food provides energy from calories and nutrients such as protein, fat and carbohydrates, vitamins, minerals and water.
Carbohydrates and proteins provide 4 calories of energy per gram, while fat provides 9 calories per gram. Humans and other animals need a minimum of food to maintain their metabolism, which is driven by their muscles. During physical activity, the body consumes calories from food in three parts of the energy system.
Atwater time factors for protein, fat, carbohydrates and food groups are used to calculate the energy value of individual foods. This system is used to estimate the apparent ME of food and uses the Atwater constant, which refers to the kilos of energy that each component of the food (carbohydrates, protein and fat) provides (Merrill and Watt, 1955 ). For foods that provide significant amounts of energy (e.g. Protein in a normal diet) are energy conversion factors different in the system shown in the table below: for example, 1.02 kJ / g (2.44 kcal / g ) for vegetable protein and 1.82 kJ / g (4.36 kcal / g) for eggs.
The amount of energy a food has per gram is called its energy density, which we will describe as fat, which is higher in energy than protein or carbohydrates. The Food and Agriculture Organisation recommends that 55% of food energy is obtained from a variety of carbohydrates. Foods rich in complex carbohydrates and proteins are the best choice for a day of energy, according to registered dietitians and nutritionists we spoke to.
Fill yourself with powerful foods that give you energy and maintain your energy levels, from breakfast to dessert. Instead of opening a sugary, filling energy drink or pouring a cup of coffee, feed yourself nutrient-rich, energy-saving foods that give you the energy to last for all day. Certain foods provide more vitamins and minerals than the energy they provide, so choose nutrient-rich foods to meet your daily energy needs.
How much energy they provide depends on the amount of carbohydrates (sugar, starch, protein, fat and alcohol) contained in the food or drink, as well as the portion size. There are 12 common foods to choose from to provide the body with energy, provided that the energy released is healthy and carbohydrates are the most important source of energy in the body.
The energy content includes energy from protein, fat and carbohydrates, as well as from ingredients in certain foods and factors that are less well known. In snacks, for example, most of the energy comes from fat, carbohydrates, and protein, but there are three energy sources that should be considered.
In rats, the need for food energy to support basic life functions, vital cell activity, respiration, cardiovascular distribution and blood is expressed in the form of metabolic body size, commonly called the Basal – Metabolic Rate (BMR). BMR defines the basic energy requirement of an animal in a post-absorbent state housed in a thermal neutral environment (Curtis 1983). Basal requirements are considered equivalent to maintaining the energy requirement in the metabolic balance of the animals.
Nutritional information includes how many calories a food has, how many carbohydrates, fats and proteins are present (calories per gram) and which energy source is used. Knowing the number of calories and nutrients, you can calculate and estimate how many calories are contained in a food you should eat.
The human body spends its energy expenditure on energy absorption. Using the International System of Units ( ISO ) researchers measure energy in J (J) and joules (J ), with several Kilojoules (KJ ) being the most commonly used food-related quantity. In Australia, we use KJ to measure how much energy people lose from consuming food and drink.
The most common standard unit of energy consumption in humans is the energetic use or expression of energy through food. To emphasise that food sources are not nutrients, alcohol is not a nutrient, but it provides 7 kilocalories of energy per gram.
Food conversion factors reflect the amount of energy provided by food components (e.g. Protein, fats, carbohydrates, alcohol and novel compounds such as polyols and organic acids used by human organisms) as an input to the energy balance. The system uses a single factor, the energy-producing substrate (usually protein or fat or carbohydrates) of the food in which it occurs.
Excessive food energy absorbs more energy from food than the body needs for its function, leading to the restoration of fat. The consumption of food energy leads to an accumulation of body fat and overweight / obesity, which increases the risk of disease. The consumption of unhealthy foods, consisting of a high proportion of energy-rich nutrients, a poor diet with high fat, sugar and salt compounds, and low physical activity, is a major cause of excess body weight and associated diseases.
Nutrition science includes behaviours and social factors related to food selection. This EatWell guide shows the different types of food and beverages we should consume in relation to a healthy, balanced diet. Food and drink provide the energy and nutrients you need to be healthy.
