Metabolism is the total amount of the biochemical reactions involved in maintaining the living conditions of the cells in an organism. All living organisms require energy for different essential processes and for producing new organic substances.


Living organisms are unique, as they obtain their energy from the environments and use it to carry out activities such as growth, development, movement, reproduction, etc.

How do the cells in the body extract energy from their environments?

In the process of metabolism, enzyme-mediated chemical reactions take place in the living organisms which converts the energy obtained from the nutrients into readily available materials into the molecules required for growth and maintenance.

Metabolism is usually divided into two categories.

Metabolic Processes

  • Catabolism – This process is mainly involved in breaking down larger organic molecules into smaller molecules. This metabolic process releases energy.
  • Anabolism –  This process is mainly involved in building up or synthesizing compounds from simpler substances required by the cells. This metabolic process requires and stores energy.

Metabolism is related to nutrition and existence of nutrients. Bioenergetics describes the metabolism as the biochemical subways through which the cell obtains its energy. One of the major aspects is the energy formation.

Nutrition and Energy

Nutrition and Energy

The processes of metabolism depend on the nutrients that get digested to produce energy. This energy is necessary to synthesize nucleic acids, proteins and other biomolecules in our body.

Encompass nutrients includes various substances for the body requirements like the sufficient amount and insufficient resulting in poor health, concerning metabolism.

Necessary nutrients help by supplying required energy and other necessary chemicals that body cannot synthesize on its own. Food provides different substances that are essential for the bodybuilding and repair of tissues along with proper functioning of the body.

The diet requires both organic nutrients and inorganic chemical compounds.

Organic nutrients include fats, vitamins, carbohydrates, and proteins.

Inorganic chemical compounds include oxygen, water, and other dietary minerals.

How to Increase Metabolism?

  • To be fit and healthy we need to avoid more calories intake and lose extra pounds. We eat to deliver energy for our body to perform its functions. Eating too little quantities could slow down our metabolism and body cannot provide essential minerals. As per the research, extreme dieting leads to weight loss which is muscle mass and not fat mass.                                                                                         
  • Having proper breakfast, boost up the body’s metabolism and keeps us energetic throughout the day. Skipping morning breakfast are more likely to have poor metabolic energy.

  • Caffeine stimulates the central nervous system and can activate our metabolism rate by 5 to 8 percent.

  • According to researchers, fiber can helps in burning fat by 30percen. People who include more fiber in their diet remain fit and healthy.

  • By including more organic foods like peaches, bell peppers, celery, apples, lettuce, grapes as it boosts up the metabolism rate in our body.
