Calories are used in many places, such as in food labels and restaurant menus. You can even see the number of calories being burned as you get on your treadmill. So what exactly do we mean by the word calories?
The word ‘calorie’ refers to a certain unit of measurement. It is used to measure the amount of energy found in a certain food or the amount of energy burnt by your body.
How many calories are needed by your body?
The answer to this question depends on the following factors:
- Physical Activity – The amount of energy that you use depends on your daily physical activities.
- BMR or Basal Metabolic Rate – This refers to the amount of energy that is needed by your body when at rest to be able to continue performing vital functions (i.e. for breathing, heart beating, etc).
Calories are fuel
Your body needs fuel and this fuel refers to calories that you obtain from food. As mentioned earlier, calories are needed to keep your vital organs working. You also need calories when your tissues are growing and repairing. The more active you are, the more calories you will burn. Lesser movement means the fewer amount of fuel being burned by the body. Therefore, those who are living a sedentary lifestyle and who sit for long periods of time due to their employment requirements should limit their calorie intake. If they do not, the weight gain is inevitable.
If your body is burning more calories than what you take in you are giving your body the opportunity to burn your energy reserves. These reserves have been stored by the body in the form of fats. As you allow your body to burn more of your fat reserves, the more likely you will lose weight. This is why complete awareness of your calorie intake and expenditure is considered an integral part of every weight loss program.
A healthy diet and a successful weight loss program require you to track not just your calorie intake. You should also track the amount of fats, proteins and nutrients being taken in on a daily basis.
It is very important to understand your own calorie requirements. Here is my personal story. I have heard many times that on average a female needs to consume around 2000 calories per day for weight maintenance. I never bothered checking my personalised calories requirement. To be honest with you, I was really surprised to see that I should not go beyond 1600 calories per day to maintain the same weight. To initiate weight loss, it was suggested that my calories intake per day should not exceed 12oo. No wonder I have been accumulating and storing unnecessary ‘energy reserves’. My approach to the diet has changed since then. Now I am on smaller portions, healthier choices, and more physically active.
