Calorie is defined as the measure of energy. Energy comes from the foods we eat. The content of calorie is basically the amount of calories which certain food contains in a given size.
It appears that most weight-loss diets focus mainly on the calorie amount rather than nutritional contribution of ingredients or healthy calories which makes up the meal.
Their Importance to Our Bodies
We cannot live without food nor can we survive on water alone. Therefore, we need food for our structural growth as well as development of our body, the energy to perform day to day activities, both mental and physical, ailment and disease prevention among others.
It is important to remember that we get calories from the energy that we get from food. Bottom line is you starve to death if there is no food.
The Amount We Need
According to research, the daily recommended intake for people between the ages of 30-50 years is 2,100kCal for women and 2,700kCal intake for men who go on daily life activities in addition to walking 1.5-3 miles at 3mph. However, this is not an ink-on-the-wall kind of thing because we are all active at different levels and every metabolism needs its own calorie requirements.
This means that a good amount of calorie intake for your wellbeing body depends on age, sex, and levels of mental and physical activities, individual metabolism and health conditions. And for calorie intake for weight loss purposes, the general agreement is that the more one is physically active, the more intake of calorie he needs because he burns a lot and vice versa.

What Happens In Case We Don’t Burn or Use Our Calories
Our bodies are meant to convert the food we eat into energy, and store it for necessary of future use.
Extreme physical activities such as exercising will require more energy, hence, we burn calories. At the same time, the energy which we don’t use is then converted and stored as tissue or body fat. Therefore, the more you consume high calorific food, the less you are physically effective, and the more you are to put on more weight by additional fat which the body creates in order to store additional calories.
That’s why it is important to know that exercise burn calories and you should be physical active.
