What is Metabolism?

Have you ever heard someone say they can’t lose weight because they have a slow metabolism? Well, it is true that metabolism is linked to weight but having a slow metabolism is usually not the main cause of weight gain.

By definition, metabolism is the body’s process that expends energy and burns calories. It works 24/7 to convert the food we eat into energy so we can breathe, circulate blood, grow, and repair. Your metabolism controls how much of that energy your body uses.

Metabolism is broken down into two processes: anabolism and catabolism. Anabolism is the storing of energy, supporting new cells, and maintaining body tissues. Catabolism is the breaking down of energy to move, heat, and energize your body.

How fast or slow your metabolism works is determined mostly by your genes, however, there are things you can control that affect your metabolism.

Physical Activity

As you age, you gain fat and lose muscle. You may also become less active. If you want to keep your metabolism revving, ramp up your physical activity.

Eat Protein

Your metabolism increases when you eat, digest, and store food (a process called thermogenesis). Protein has a higher thermic effect compared to fats and carbohydrates because it takes your body longer to burn and absorb protein.

Sleep

Sleep helps regulate glucose or blood sugar. Lack of sleep can affect glucose levels, leading to a lack of energy. Studies have shown that sleep deprivation can also alter hormones involved in regulating metabolism.
