Question

a person who does not get proper amount of nutrients in food is said to suffer from obesity​

Answer 1

Answer:

Obesity is generally caused by eating too much and moving too little.

If you consume high amounts of energy, particularly fat and sugars, but do not burn off the energy through exercise and physical activity, much of the surplus energy will be stored by the body as fat.

Calories

The energy value of food is measured in units called calories. The average physically active man needs about 2,500 calories a day to maintain a healthy weight, and the average physically active woman needs about 2,000 calories a day.

This amount of calories may sound high, but it can be easy to reach if you eat certain types of food. For example, eating a large takeaway hamburger, fries and a milkshake can total 1,500 calories – and that's just 1 meal. For more information, read our guide to understanding calories.

Another problem is that many people are not physically active, so lots of the calories they consume end up being stored in their body as fat.

Poor diet

Obesity does not happen overnight. It develops gradually over time, as a result of poor diet and lifestyle choices, such as:

eating large amounts of processed or fast food – that's high in fat and sugar

drinking too much alcohol – alcohol contains a lot of calories, and people who drink heavily are often overweight

eating out a lot – you may be tempted to also have a starter or dessert in a restaurant, and the food can be higher in fat and sugar

eating larger portions than you need – you may be encouraged to eat too much if your friends or relatives are also eating large portions

drinking too many sugary drinks – including soft drinks and fruit juice

comfort eating – if you have low self-esteem or feel depressed, you may eat to make yourself feel better
