Metabolism And Weight Loss: How You Burn Calories

Find out how metabolism burns calories, how it affects your weight and ways you can burn more calories for greater weight loss.

You likely know your metabolism is linked to your weight. But do you know how?

Common belief holds that a slim person's metabolism is high and an overweight person's metabolism is low. But this isn't usually the case. Weight isn't necessarily directly linked to metabolism.

Instead, weight is dependent on the balance of total calories consumed versus total calories burned. Take in more calories than your body needs, and you gain weight. Take in less and you lose weight. Metabolism, then, is the engine that burns these calories.
Metabolism: Converting food into energy

Stated simply, metabolism is the process by which your body converts food into energy. During this complex biochemical process, calories — from carbohydrates, fats and proteins — are combined with oxygen to release the energy your body needs to function.
