Oct 15, 2019 Kayode Oseh

Virtually everyone knows or must have heard of the word calorie. This word has become very popular among several individuals and cultures, all thanks to obesity. Most people wouldn't have known what this word means if not that obesity is becoming a problem in our society.

Scientifically, a calorie is the amount of heat energy needed to raise the temperature of one gram of water by one degree Celsius. But when you come to nutrition, it means the amount of energy people get from food and drinks they consume. Also the amount of energy they expend during physical activities.

Foods we eat contain lots of stored energies which are called calories, these energies are needed if the body must function always. For example, our brain is able to function because of these energies, our heart is able to beat because these energies, our liver and kidney all rely on these energies. 

All foods contains calories. But some foods contain much more calories than others especially foods rich in fats. Whenever we eat food, our body use these calories (energies) in the required amount in order to carry out it normal activities. While the remaining ones that were unable to be used up by the body, are stored in different tissues and organs. As we continue to eat food, more and more of these foods with their calories are being stored in the body. And the more they are stored, the larger and bigger our body tend to look and that's where obesity sets in

Why does "Junk foods" increases obesity?


Junk foods are foods that are very rich in fats and sugars. These are the two major things that tend to contain lots of calories most especially fats. The more junk foods you consume, the more sugar and fat you take in. The more sugar and fats you take in, the more calories you accumulate. The more calories you accumulate, the more your body store those calories. And the more your body store calories, the more obese you become. I'm pretty much sure you understand vividly from this explanation?

How does physical exercise burn fat?


You need to exercise so that you can burn lots of fats, because excess fats stored in your body makes you obese. Don't forget we made mention earlier that 'calories are energies contained in food' and that fats contain lots of those energies. Remember that exercise is a physical activity that requires the use of energy. When you exercise, your body use a lot of those calories (energies) present in the fats in order to provide the energy needed for that physical activity.

It means that as you continue to exercise, the more your body is consuming those energies in the stored fats. And the more these energies are used up, the more fats you loose. That is what it means to burn fat or burn some calories.

The reason you sweat a lot during physical exercise is because calories are also called heat energies. These energies makes your body to release a reasonable amount of heat during body activities.
