Calorie: Calorie in scientific sense is defined as the amount of heat required to raise the temperature of 1gram of water to 1 degree centigrade.
But in nutrition sense,it is defined as a unit of energy produced which is equal to amount of heat contained in food and released upon oxidation by the body.
Daily caloric Need: The daily caloric requirment for normal people ranges from 1800-2400calories.But people become obese due to the consumption of more calories than required.Obesity also results due to lack of exercise which ultimately leads to the conversion of these calories into fat.The daily caloric requirement varies from age and gender also.This is shown in the table below.
If we consume more calories and do not spend all them then it is called positive energy balance.This is good for people who suffer with underweight. Who want to maintain their weight is spend as many calories as you consume.The other thing is spending more calories than that we consumed.This is called negative energy balance.
We can lose weight healthily by consuming the same number of calories as required normally by spending more calories than consumed.It means that if we consume 1800cals we must spend 2300cals.This is in another words also called negative energy balance.This is the best range .If anyone goes beyond that range(i.e spending 2500cals and consuming only 1800kcals) may suffer from lots of problems like aneroxia etc.This must be the aim to lose weight safely without any side effects.

Daily Caloric requirement:
| Name | Calories |
|---|---|
| Children | 1200kcals |
| Teens girls and boys | 1400-1800kcals |
| Adult women | 1800kcals |
| Adult men | 2200-2400kcals |
