Losing weight is no easy task. You have to give up on your favorite fatty and sugary foods and exercise regularly. However, when you see the pounds dropping whenever you step on a weighing machine, it all becomes worth it.
What happens to this weight?
Have you ever wondered when you lose weight, where does it go? You had excess fat before and now it’s not there. So what happened to it?
Our body needs energy to survive:
The fact is that everything you do requires energy. Even when you are breathing, your body is utilizing energy.
Body burns calories while performing different activities:
Whenever you are doing anything, your body produces the energy needed to complete the task by burning and utilizing the food that you eat.
Several complex reactions occur inside cells which produce energy and burn off calories.
The more you exercise, the more energy is needed:
For example, if you are running, your body needs more energy to keep you going. Therefore, more calories will be burned off to produce this energy.
Kreb’s cycle is the series of reactions that occur in the body to produce energy. Basically, the food you eat gets converted into carbohydrates, fats and amino acids. In Kreb’s cycle, the carbs as well as fats are further degraded and as a result Adenosine Triphosphate (ATP) is produced.
What is ATP?
ATP is the energy currency of the body. It is utilized whenever energy is required by the body. Therefore, ATP is used during respiration, movement and metabolism.
The body gets rid of waste products in the form of stool, urine and sweat. When these are excreted, heat is removed from the body.
Mainly, the weight we lose gets converted into heat:
When you lose weight, most of it is lost in the form of heat. No matter what you are doing, energy is being expended and heat is being produced. Most of the calories that are burned off are lost as heat and only some of it gets converted into energy.
Loss of carbon dioxide:
When you breathe, you exhale carbon dioxide while you take in oxygen. Carbon dioxide is heavier than oxygen, so when you exhale more of it during exercise, you are also losing weight this way.
