What Is Metabolism?
Metabolism is one of our body processes that are vital to sustaining life. It is the process by which the body utilizes nutrients present in food (carbohydrates, proteins, and fats) to make energy.
Oxygen is involved in this process by which the nutrients undergo changes along the process. Energy is the end product of this reaction. This energy is used to perform daily activities of life and also is used for the functioning of the body’s organs. It involves all the chemical reactions involved in the maintenance of body cells.
The Two Main Parts Of Metabolism
Catabolism: the process of breakdown of nutrient molecules to release energy
Anabolism: the process of synthesis of compounds essential for cell functioning.
Role Of Nutrition In Metabolism
Metabolism is important as it is not only involved in energy production for the body but is also involved in the synthesis of new molecules such as proteins and DNA which is constantly required by the body cells for maintaining optimum health and well-being.
The fuel for the metabolic process is nutrients present in foods. Food plays an important role and is directly associated with the metabolic process. It supplies the body with energy and also some chemicals that the body cannot synthesize on its own.
These chemicals help in building, maintenance, repairment, and optimum functioning of the body. The major nutrients supplied are carbohydrates, proteins, and fats for energy and micronutrients (vitamins and minerals) for tissue building and repairment. Through this process of metabolism, the following nutrients perform their functions in the body, the main role of nutrients are
Carbohydrates: Body’s first source of energy and provides energy to the brain in form of glucose
Proteins: they have a role in tissue repair and maintenance
Fats: they have a structural role in the body and cushions the body’s organs
Vitamins & Minerals: vitamins such as Vitamin A, Vitamin B2, B3, and B5 cannot be synthesized by the body. And minerals such as calcium, phosphorous, iron, sodium, potassium, iodine, copper, and zinc play a regulatory role in metabolism so must be supplied from food.
Basal Metabolic Rate
When our body is at rest it still needs energy (calories) to perform basic functions for sustaining life. Processes such as breathing, circulation, nutrient processing, and cell production, etc constantly rely on energy provided from food. BMR is the number of calories that the body uses to perform these functions
Why Do You Need To Know Your BMR?
As it is the estimation of calories needed for the body to function if the calories exceed the amount required by the body it will cause you to gain weight. If the calories from food are below that required by the body it will cause weight loss and hinder with body’s normal functions leaving you with a feeling of fatigue and tiredness. The formula to measure your BMR is by using the Harris benedict equation,
Male: 66.5+ (13.8x weight (kg)) + (5.0xheight (cm))-(6.8xage)
Female: 655.1+ (9.6xweight) + (1.9xheight (cm))-(4.7xage)
Factors affecting BMR
What Is An Optimum Metabolism And Why Is It Important?
An optimum metabolism is one in which the calories being consumed by the body through food are equal to the calories that the body is burning. There should be a balance of calories consumed and calories burned. For this reason, physical activity is an important factor.
For a person with a sedentary lifestyle, the calorie requirement is less as compared to the one with an active lifestyle. If this is not the case then it will lead to physical and chemical changes in the body. It will cause us to either gain weight or lose weight. Also if the quality of food is not good it can lead to disorders. For example, if the amount of simple carbohydrates in the diet is high it will cause diabetes mellitus as it will disturb the glucose metabolism.
Vitamin B Complex and Metabolism
Vitamins are important to maintain optimum body’s metabolism and hence optimum health. It plays a regulatory role in the process of metabolism. Our Vitamin B complex is a combination of all types of B vitamins (B1,2,3,5,6,7,9 and 12) that are needed to support metabolism. It regulates the metabolism of carbohydrates, proteins, and fats in this way these nutrients can serve their functions in our body. Apart from metabolic functions, this product is good for neurological functions as well.
