How does metabolism work?

Sal Di Stefano AI:

Metabolism is a complex process that involves the conversion of food and nutrients into energy that our bodies can use. It's essentially the rate at which our bodies burn calories. There are a few key factors that influence metabolism:

  1. Basal Metabolic Rate (BMR): This is the number of calories your body needs to perform basic functions at rest, such as breathing and maintaining body temperature. It accounts for the majority of calories burned each day.

  2. Physical Activity: The more active you are, the more calories you burn. Exercise and movement increase your metabolic rate temporarily, even after you've finished working out.

  3. Thermic Effect of Food (TEF): Digesting, absorbing, and storing food requires energy. The TEF refers to the calories burned during this process. Protein has a higher TEF compared to carbohydrates and fats, meaning it requires more energy to digest.

  4. Muscle Mass: Muscle tissue is more metabolically active than fat tissue, meaning it burns more calories
