Understanding Metabolism

Valleant - Understanding Metabolism

Metabolism is the complex network of biochemical processes that the body uses to convert food into energy. This energy is essential for everything from breathing to thinking to exercise. The rate of metabolism varies among individuals, influenced by factors such as age, sex, genetics, muscle mass, and physical activity levels.

There are two primary components of metabolism:

  • Basal Metabolic Rate (BMR): The amount of energy expended while at rest. It represents the minimum amount of energy required to keep the body functioning, including breathing and maintaining body temperature.
  • Thermic Effect of Food (TEF): The energy used in the process of digestion, absorption, and distribution of nutrients.

Factors such as hormones and diet can influence metabolic rate. For instance, the thyroid hormone is instrumental in regulating metabolism. Additionally, muscle tissue burns more calories at rest than fat tissue.

Physical activity also boosts metabolism temporarily. Higher intensity workouts have a more significant impact on the post-exercise oxygen consumption, which can increase metabolism for hours after exercise.

People often seek supplements to enhance their metabolism. It’s important to approach this with caution, as not all supplements are effective or safe. Here is a brief list of supplements sometimes associated with metabolic support:
