Metabolism

Definition

Metabolism is the process by which your body converts what you eat and drink into energy, allowing you to perform vital functions.

Scientific / Technical Definition

Metabolism refers to the biochemical processes that occur within a living organism to maintain life. It involves two main types: catabolism, the breakdown of molecules to obtain energy, and anabolism, the synthesis of all compounds needed by the cells.

Benefits

• Helps in maintaining a healthy weight
• Supports overall body energy levels
• Assists in growth and cell repair
• Enhances nutrient absorption

Examples

• The energy used when resting or sleeping
• Calories burned during physical activity
• The energy required for digestion

Additional Information

• Effects: Metabolism affects how your body burns calories and how efficiently it processes nutrients from food. A higher metabolism means you burn more calories at rest and during activity.
