According to Wikipediahealthy diet or balanced diet is a diet (what you eat) that contains the right amounts of all the food groups. It includes fruits, vegetable, grains, dairy products, and protein. It does not include too much or too little of any kind of food.
The food which we eat is known as Diet and it is the basic requirement of every individual. Diet is the daily intake of food by human body.
It provides energy for workout along with growth and development of the body. Human beings take different types of food in their diet; it may be liquid food or solid (hard) food.
These things which we eat give energy to our body for performing work in a proper way. Our body grows, develops and functions properly with the help of macro and micronutrients in the food.
Balanced diet is that diet which contains all nutrients (macro and micro) in correct proportion for efficient working of the body.
In other words, it is intake of appropriate type and adequate amount of food to supply energy and to support growth and development of an individual.
Balanced diet contains all nutrients (macro and micro) in sufficient quantity and it fulfils the needs of the body. The food contains various types of nutrients in it.
Nutrition : Nutrition is the food which provides energy for workout along with growth and development of the body.
Our body grows, develops and functions properly with the help of nutrients in the food. The food contains various types of nutrients in it like Carbohydrates, Fats, Proteins, Vitamins, Minerals and Water.
It is of two types :
(a) Macronutrients : These are required in large proportion in our diet like carbohydrates, fats and proteins. They are the main part of diet and they are taken in large quantity in our diet.
They are the main source of energy and body development, such as Carbohydrates, Proteins, Fats, Fibres (Roughage), Water.
(b) Micronutrients : These are required in small proportion in our diet like vitamins and minerals. They are considered as supplement food. They act as defensive food and help the proper functioning of various organs of the body.

Components of Balanced Diet

(a) Energy Yielding Food : It consists of carbohydrates and fats food (macronutrients) items. This food helps to provide energy to individual for his workouts or activities.
The carbohydrates should be 60 to 70 per cent in our diet whereas majority of carbohydrates should be complex carbohydrates. The fat content should not exceed 5 to 10 per cent in our diet.
Carbohydrates are easy and good source of energy whereas fats are difficult to digest and more difficult to get energy from it. Thus, fats should be less in our diet. Moreover, they cause the chances of overweight, obesity and heart diseases.
(b) Body Building Food : It consists of proteins. It helps in the growth and development of body. It helps to repair or replace the worn out tissues. It provides faster recovery from injury. Proteins should be 15 to 20 per cent in our diet.
(c) Defensive Food : It consists of vitamins, minerals and water (micronutrients). This food helps in proper functioning and defence of various organs.
This diet improves the immune system of the body, thus it helps to defend against infections, germs, diseases, etc. This food should be 15 to 20 per cent in our diet. Apart from this one should drink 3 to 5 litres of water to maintain water balance of the body.

Energy Requirement of an Individual

The daily energy requirement of an individual is evaluated by adding the Basal Energy Requirement (BER) with Extra Energy Requirement (EER). The energy value is measured in heat unit called Calorie or kilocalorie.
One calorie raises the temperature to one degree from one gram. A kilo calorie is written as Calorie with capital C.
The Basal Energy Requirement (BER) is calculated by multiplying the body weight (in kg) by 24 hours (one day) with 1.3 Cal. As 1.3 Calorie is required per kilogram, per hour of BER, i.e.
1.3 Cal x body weight (in kg) x 24 hr = Basal Energy Requirement (BER).
If a person is with body weight 60 kg then Basal Energy Requirement (BER) is
1.3 Cal x 60 kg x 24 hr = 1872 Cal per day.
The Extra Energy Requirement (EER) is calculated by multiplying the body weight (in kg) by hours of training with 8.5 Cal. as 8.5 Cal is required per kilogram per hour of EER.
If a person is with body weight 60 kg and performs 2 hours training then Extra Energy Requirement (EER) is
8.5 Cal x 60 kg x 2 hr = 1020 Cal for two hour training.


During rest and sleep, body rebuilds its tissues that help in growth. The duration of rest, sleep and relaxation varies with the age, activity, sex.

An infant needs more sleep than an adult. During sleep, growth and development become active. In this period repair of cells, rebuilding of new cells, recovery from injuries, etc., are carried out in body.
For adult a sound sleep for 6 to 7 hours is sufficient to provide recovery. A person who is performing strenuous (hard physical) work needs adequate rest by which recovery is provided.
Relaxation refreshes us. It is commonly believed that we should have proper rest, relaxation and recovery before the next work. It should neither be too long nor too short.
This is known as ‘three R formula’.

Importance of Sleep and Rest:

  • It gives relaxation to various systems of the body so that they should work efficiently.
  • It helps us to refresh ourselves and carry out the work as before.
  • It saves the heart, pumping blood against the force of gravity.
  • It rejuvenates our body from the effect of fatigue.
  • It refreshes our mind for the next day.

Most of us have experienced trouble sleeping at one time or another. This is normal and usually temporary, due to stress or other outside factors.

The lack of quality sleep can have a negative impact on your energy, emotional balance, and health.


Insomnia, the inability to get to sleep or sleep well at night, is a very common sleeping problem. In fact, it is the most common sleep complaint.

Obesity means excessive accumulation of fats in the body and tendency of an individual to become fatty due to this. It is a health problem in which the body gains lot of weight, i.e. overweight of body (abnormal).
In this problem the non-consumed (extra) fats of the body deposited under the skin. This deposition of fats takes place especially in areas like the abdomen chest, shoulder, buttocks and legs.
Sometimes the excess of fats can also be noticed on neck, chin and cheeks. Obesity causes many health problems like loss of physical efficiency: irregular shape or figure of body; decline of physical personality (appearance); feeling of tiredness while performing activity, inability to perform hard physical activity, cardiovascular problems, etc.
This disorder of body can be prevented by the combination of various methods. The obesity le can be calculated by the formula of “Body Mass Index” (BMI).
In this testing index the health and fitness abilities of an individual are based upon the relationship of height and weight. Here height is considered in metres and centimetres : weight is considered in kilograms and grams.
BMI is calculated by taking person’s weight (in kg and gm) and dividing by height (mt and cn) square, i.e., Weight + (height x height)
Example : For instance, if your height is 1.82 m, the divisor of the calculation will be (1.82×1.82) = 3.3124. If your weight is 70.5 kg then your BMI is 21.3 (70.5 3.3124 Higher the figure, the more overweight is the person. This is just a guide to know overweight content in the body. This test can be a preventive step towards obesity.
Causes of Obesity : The basic causes of obesity are wrong dietary habits and less physical activity like overeating: taking lots of fats and fried food taking lots of animal flesh, eating lots of sweets eating junk food: drinking alcohol, less physical activity: sedentary lifestyle, etc.
In same cases it is due to hormone variation (by drugs or medicines). Some people inherit this problem from their parents.
