Definition
Your metabolism refers to all the chemical reactions in the body that convert food into energy and keep you alive. It’s the sum of processes managing energy balance.
Explanation
- Metabolism breaks down the carbohydrates, fats, proteins and alcohol you consume into smaller units that can be used for fuel, building tissues and other functions.
- The three components are resting metabolism from vital functions, physical activity, and the thermic effect of food digesting nutrients.
- A faster metabolism uses more calories day which helps regulate weight but is largely genetically influenced. Thyroid function greatly impacts it as well.
- Strength training plus protein intake helps sustain an elevated metabolism versus severe calorie reduction alone.
Examples
- Someone maintains a fast metabolism and leanness despite overeating.
- Interval training and weightlifting boosting metabolic rate for hours after exercise.
Related Terms
- Caloric expenditure, energy balance, metabolic damage, REE
Common Questions
- How can I speed up a slow metabolism? Resistance training, protein intake, and activity in general boosts metabolism.
- Is a very fast metabolism good? Generally yes for health, but hard for some ectomorphs to gain weight.
Do Not Confuse With
- Metabolic syndrome – Condition with insulin resistance risks, not metabolism rate.
