A calorie is a unit of energy. There two types of calories:
A small calorie (cal) being the amount of energy required to raise one gram of water by one degree Celsius;
A large calorie (Kcal) being the amount of energy required to raise one kilogram of water by one degree Celsius.
A calorie is used to measures the amount of energy stored in food, and we all need energy to survive – to breath, move, pump blood and more. We eat and drink to put energy in our bodies. The number of calories in a food item is a measure of how much potential energy the food has.
- A gram of carbohydrates has 4 calories.
- A gram of protein has 4 calories.
- A gram of fat has 9 calories.
When we eat and drink more calories than we use up, our bodies store the excess as body fat. As the same routine continues, we find ourselves putting on weight. To achieve and maintain stable weight, the energy we put into our bodies must be the same as the energy we use whether on bodily functions or physical activities.
Medical Practitioners always insists that we reduce on our calorie intake, but the question is by how much. In my own opinion, calories are as important as much as they are regarded not to be harmful to our bodies. Therefore, we switch our focus to the number of calories one needs, because our bodies do not required the same number of calories each day.
I conclude and say calories are not as harmful as they are framed to be, but it is important to check on the quantity you take in. Am sure there are questions running through your mind:
- How do I know the right number of calories to take?
- What is the daily recommended calorie intake?
- What are zero-calorie foods?
- Which foods and drinks are low in calories?
