Healthy Facts About Digestion And Weight

What is Digestion?

Effective DigestionDigestion is the process of breaking down components of food into smaller, absorbable parts. The process of digestion is a chemical and mechanical process in which the components of food are broken down into a form that can be easily digested by the human body. These components of food are broken down into a form that can be absorbed by the blood. When broken down, the food is no more in its original form. When the components are absorbed by the blood, the minerals, vitamins, carbohydrates, fats, proteins and salts are supplied to the various organs of the body for functioning.

Reason Of Over Weight:

The weight of a person is the result of what a person eats, how much exercise the body gets and the amount of intake of food. The weight depends on Basal Metabolic Rate, commonly known as the BMR. Digestion and weight are related through the Basal Metabolic Rate index. Basal metabolic Rate is the quantity of energy extracted from the food that we eat, after its absorption takes place in our body. This energy that is released is just enough for the vital organs of the body to perform their respective functions. BMR Is measured when a person is at rest.

The vital organs of the human body include the heart, nervous system, brain, kidneys, lungs, liver, skin and the muscles. It is a known fact that the basal metabolic rate declines with increasing age. Digestion is the factor on which the basal metabolic rate depends. If food digestion in a person is effective and fast, the person has a lower basal metabolic rate. On the other hand, if food digestion in a person is slow and inefficient, the person is bound to have a higher body mass index. People with body mass index under a certain level are categorized as being of normal weight.

Those people who have a body mass index higher than the normal, within a specified range are said to be overweight. When the body mass index exceeds this specified limit, a person is said to be obese. Obese people are those whose intake of food is much more than what their body system can digest. The energy from the food they eat is not extracted completely and is stored as fat. Also, that energy which is extracted is not spent due to lack of exercise and hence results in obesity. Therefore, effective digestion is the key the correct body weight.
