Metabolism can be defined as a set of biochemical processes that occur within every living organism to maintain life, including humans. These processes help us to grow, repair damage to our body, reproduce and respond to their environment. All these processes use energy.
It is a common belief that metabolism refers to the rate at which the body burns calories. People generally confuse metabolism and Basic Metabolic Rate (BMR) with each other. Our body’s metabolism is controlled by the Thyroid Gland.
Fast Facts: –
- Basal metabolic rate (BMR) accounts for up to 70% of your total energy expenditure. It is the rate at which our body uses energy while at rest.
- A person’s metabolic rate can be influenced by genetics but not completely. They can improve it by maintaining a healthy lifestyle (exercise and healthy foods).
- It can be affected by many different health conditions.
- Anything that harms your thyroid negatively can harm your metabolism.
- This term is also used to define catabolism and anabolism collectively.
- Catabolism is the breaking down of compounds to release energy and anabolism is building of compounds that use energy.
- Eating foods with more protein can boost our body’s metabolic rate by increasing the amount of calories you burn, foods such as salmon, eggs, soy, chicken, turkey and beans are all excellent sources of protein.
- Body weight is a result of catabolism minus anabolism – the amount of energy we release into our bodies minus the amount of energy our bodies use up.
- Our bodies gain weight when it starts storing excess energy as fat.
