Metabolism refers to the process of converting the calories you intake into energy to power your body. Your metabolism determines the amount of calories you can eat all day and still maintain your weight. It’s affected by 3 main things:
- Basal metabolic rate (AKA BMR): Tells you the number of calories needed to maintain your body in a rested, fasting state. It’s affected by your gender, age, size, muscle mass, genetics and health-related factors. Your BMR accounts for 60-70% of the total calories you burn each day.
- Activity level: Tells you the number of calories you use up during exercise or activity. Your activity level accounts for about 20% of the total calories you burn each day.
- Food thermogenesis: Tells you the number of calories you need to digest and absorb your food. It accounts for about 10% of the total calories you burn each day.
Anything that affects the 3 things mentioned above will change the amount of calories you need to maintain your body weight. Your basal metabolic rate is adaptable, and it will increase or decrease to provide for your body’s needs. check it out:
- Your metabolism goes up and burns more calories during a fever or infection to help your body heal.
- Your metabolism goes down and burns less calories during a long fast to conserve calories and prevent you from fading away. That is one of the reason why some body builders eat more often to trick your metabolism
