The daily needs are calculated using formulas that are based on a person with average metabolism.
Nonetheless, most sources for healthy nutrition and exercise recommend tracking the daily calorie intake. Calorie density or energy density is a useful concept in nutrition. It refers to the amount of calories per gram of food. Foods low in calorie density often have a high water content. They fill the stomach and give the feeling of fullness with fewer calories than a food high in calorie density would.
For example, there are calories in grams of chocolate just a little less than half a cup , which is about the same as in grams 1. Perhaps, it is easier to imagine that one chocolate candy contains about the same amount of calories 50 as a little over a table spoon of turkey, or 6. If one compares the feeling of fullness after eating 6 cups of cucumbers and one chocolate candy, it is very likely that eating the cucumbers will make the eater feel full, while the chocolate, on the other hand, fuels a desire to eat more.
Knowing the calorie density of foods is, therefore, very useful for people who are trying to eat fewer calories. However, while it is true that most unhealthy foods are high in fat and sugar and are also high in calorie density, anyone on a path to healthy living has to consider not only the calorie content of foods but their nutritional value as well. Nutrient density is a similar concept; it compares the amount of nutritious elements such as vitamins, dietary fiber, antioxidants, and minerals, to the amount of energy in a given food.
Thus, foods high in nutrient density are foods that have a high amount of nutrients per a given unit of energy. The opposite are the empty calorie foods that have little or no nutrition value. Alcohol is one example of such foods. Individuals should minimize consumption of empty calorie foods, especially if they are dieting, because they may not get enough nutrition.
Energy used by the human body is needed to maintain the basal metabolic rate BMR , which constitutes the amount of energy needed to support a living body at rest. This includes supporting the metabolism of the brain, as well as of the other organs and tissues.
It is also used to support physical activity. The BMR, and by extension the total energy expended increase as the body looses fat and gains muscle tissue. Both losing fat and gaining muscle help improve the metabolism and the overall health of the body, therefore it is generally recommended to combine healthy eating with exercise that maintains and develops muscles.
The effect of exercise on the energy expended by the body depends on whether the exercise is aerobic or anaerobic. Aerobic exercise uses oxygen to break down glucose and generate energy, while anaerobic exercise uses phosphocreatine instead to produce the energy needed for the exercise. Anaerobic exercise helps increase the muscle mass. It is more intense and short-term, such as sprinting and lifting weights.
It cannot be done for long periods of time because lactic acid enters the bloodstream as a byproduct of the chemical reaction needed to produce energy. The excess of lactic acid results in pain, and if the activity is continued disregarding pain, then one may even become unconscious.
Aerobic exercise, in contrast, uses endurance and is more long-term, such as marathon running. It trains muscles of the heart and the respiratory system, burns fat, and improves circulation. As briefly mentioned above, generally weight loss can result from expending more calories than consuming, but it is not always the case that this process occurs, or that it can be sustained over a long period of time.
The body uses a range of adaptation techniques to account for the lack of energy, including a slowdown in metabolism. This results in weight loss plateaus: no weight loss despite a continuing diet or exercise routine. In this situation it is recommended to add some variety to the eating and exercise routine, such as trying out a new sport, varying the calorie intake per day, or setting weekly calorie limits instead of daily ones.
One technique is calorie shifting — gradually increasing or decreasing the daily calorie intake for a given period of time, and then resetting it back to the original amount at the end of the period. Some diet plans also suggest varying the types of food and amounts per every meal, for example, eating a small lunch heavy on carbohydrates one day, and a big protein-heavy lunch the next day. The principle behind calorie shifting is to not follow a pattern so that the body does not know how many calories per day to expect and cannot adjust accordingly by slowing down the metabolism.
It is also recommended to engage in anaerobic exercises to increase muscle mass and improve metabolism, but a variety with a randomized mix of both aerobic and anaerobic is best to keep the metabolism from slowing down.
It is important to remember that muscle mass is needed for healthy metabolism, and it may help dieters to set goals of lowering total body fat instead of losing weight. Muscle tissue weighs more than fat, so when one is engaging in muscle training, some weight gain may also occur. In this situation it is useful to monitor other body measurements such as total body fat percentage, or tape measurements for different body areas such as waist or hips.
For example, energy drinks are sold as performance-enhancing beverages. They generally contain stimulants like caffeine, sometimes herb extracts, and plenty of sugar. This happens because the increase in blood flow brings more oxygen to the brain. Energy drinks should not be consumed while exercising, because they negatively affect the electrolyte balance in the body. They often contain very high levels of stimulants and provide a brief boost period followed by a withdrawal period.
Energy drinks may also have other side-effects such as nausea and vomiting, headaches, high blood pressure, irregular heart rate, and insomnia. It is better not to drink energy drinks at all.

Post your question in TCTerms and you will get an answer from experienced technical translators in minutes. Energy is understood as the ability of a physical system to do work on other physical systems. Since work is defined as a force acting through a distance, energy is always equivalent to the ability to exert pulls or pushes against the basic forces of nature, along a path of a certain length.
Energy is a scalar physical quantity. In SI, energy and work are measured in joules, but in many fields units like kilowatt-hours and kilocalories are often used.
By another definition, the joule is equal to the energy required to pass an electric current of one ampere through a one ohm resistor for one second. Electrical energy is measured by electricity meters. Thermal energy is measured by heat meters. Source: NIST. Conversion factors for energy equivalents based on CODATA internationally recommended values of the fundamental physical constants.
