How many kilojoules do I need each day? A kilojoule (like a calorie) is a measure of energy in food. On average, people eat and drink around 8700 kilojoules a day, however we're all different. To maintain your current weight, use your current (actual) body weight in the calculator below.
Food energy is defined as the energy released from carbohydrates, fats, proteins, and other organic compounds.
Here is a list of foods that have been proven to help promote energy levels:
- Bananas. Bananas may be one of the best foods for energy.
- Fatty Fish.
- Brown Rice.
- Sweet Potatoes.
- Coffee.
- Eggs.
- Apples.
- Water.
Food energy is defined as the energy released from carbohydrates, fats, proteins, and other organic compounds.
This energy comes from the food we eat. Our bodies digest the food we eat by mixing it with fluids (acids and enzymes) in the stomach. When the stomach digests food, the carbohydrate (sugars and starches) in the food breaks down into another type of sugar, called glucose.
Bananas may be one of the best foods for energy. They are an excellent source of carbohydrates, potassium and vitamin B6, all of which can help boost energy levels in your body ( 1 , 2).
The basic food groups are:
- breads, cereals, rice, pasta, noodles and other grains.
- vegetables and legumes.
- fruit.
- milk, yoghurt, cheese and/or alternatives.
- lean meat, fish, poultry, eggs, nuts and legumes.

People who are active tend to need more energy than sedentary people. For example, an adult office worker might need 10,000 kJ per day, but a manual worker might need 15,000 kJ per day.
Energy requirement is the amount of food energy needed to balance energy expenditure in order to maintain body size, body composition and a level of necessary and desirable physical activity consistent with long-term good health.
The macronutrients (carbohydrates, proteins, fats and oils) we consume in our diet help to supply the energy needed by the body to keep it working. This energy is used to drive the complex chemical, mechanical and electrical systems of the body.
The percent Daily Intake values used in DIG are based on an average adult diet of 8,700 kilojoules (kJ). Many people will require different amounts of food energy at various stages of their lives and as their activity level varies.
There are 3 sources of energy(calories) which are also known as macronutrients: carbohydrates, protein, and fat. Of these three, carbohydrates are the body's preferred source of energy. Carbohydrates break down into glucose, which is an immediate source of energy especially for the brain and muscles.
Energy content is the amount of heat produced by the burning of 1 gram of a substance, and is measured in joules per gram (J/g). where H = heat energy absorbed (in J), ∆t = change in temperature (in °C), m = mass (in g), and Cp = specific heat capacity (4.18 J/g°C for water).
It is possible, though unlikely, that eating more than that could negatively impact your health. Overall, eating eggs is perfectly safe, even if you're eating up to 3 whole eggs per day. Given their range of nutrients and powerful health benefits, quality eggs may be among the healthiest foods on the planet.
Ginseng, Gingko Biloba, and Guarana are safe when consumed individually, but when mixed with common energy drink ingredients such as caffeine and sugar, they can become dangerous.
Eating eggs leads to elevated levels of high-density lipoprotein (HDL), also known as the “good” cholesterol. People who have higher HDL levels have a lower risk of heart disease, stroke and other health issues. According to one study, eating two eggs a day for six weeks increased HDL levels by 10%.
We found 28 quick and easy tips to up energy levels — no unpronounceable chemicals required.
- Work out midday. When that mid-afternoon energy slump rolls around, hit the gym instead of the sack.
- Eat chocolate.
- Power nap.
- Drink some coffee.
- Go outside.
- Eat regularly.
- Go for complex carbs.
- Opt for sugar-free drinks.
The following fruits may help boost energy:
- Bananas. Share on Pinterest Bananas are rich in potassium.
- Avocados. Avocados are a well-rounded fruit in terms of health values and nutrients.
- Goji Berries.
- Apples.
- Strawberries.
- Oranges.
- Dark berries.

The energy in milk comes from its protein, carbohydrate and fat content, with the exception of skim milk that has virtually no fat. The energy content of some milk varieties is shown in the Nutrient Content Tables. Food provides energy to the body in the form of calories (kcal).

Heat is the transfer of kinetic energy from one medium or object to another, or from an energy source to a medium or object. This is the amount of heat required to raise the temperature of one pound of pure liquid water by one degree Fahrenheit.
Energy content is the amount of heat produced by the burning of 1 gram of a substance, and is measured in joules per gram (J/g). where H = heat energy absorbed (in J), ∆t = change in temperature (in °C), m = mass (in g), and Cp = specific heat capacity (4.18 J/g°C for water).
Energy content is an important property of food. The energy your body needs for running, talking, and thinking comes from the food you eat. Energy content is the amount of heat produced by the burning of 1 gram of a substance, and is measured in joules per gram (J/g).
To calculate this, divide a food or drink's calories from fat by total calories (this information is on the product's food label) and then multiply by 100. For example, if a 300-calorie food has 60 calories from fat, divide 60 by 300 and then multiply by 100.
Your body gets energy from calories, which come from three sources: fats, proteins and carbohydrates. Although your body can convert the calories from all three of these macronutrients into energy, fat gives you the most energy because it contains the most calories per gram.
Energy content is the amount of heat produced by the burning of 1 gram of a substance, and is measured in joules per gram (J/g). You can determine energy content by burning a portion of food and capturing the heat released to. a known mass of water in a calorimeter.
Food calorimetry allows us to determine the number of calories per gram of food. In this activity, a piece of food is burned and the released energy is used to heat a known quantity of water. The temperature change (∆T) of the water is then used to determine the amount of energy in the food.
A calorimeter is an object used for calorimetry, or the process of measuring the heat of chemical reactions or physical changes as well as heat capacity. Multiplying the temperature change by the mass and specific heat capacities of the substances gives a value for the energy given off or absorbed during the reaction.
