Metabolism is a fascinating and essential process that powers every aspect of the human body. Many people consider it to simply be how fast the body uses up energy. It does govern energy consumption, but also regulates weight and overall health.  Fully knowing what metabolism is requires some reading and working with an experienced doctor who understands metabolic health. 

Metabolism refers to the total of chemical reactions occurring within the cells of an organism. These reactions convert food and nutrients into the energy needed to sustain life. Metabolism involves two main processes: catabolism and anabolism. Catabolism is the process by which complex molecules, such as carbohydrates, proteins, and fats, are broken down into simpler compounds, releasing energy. This energy powers various bodily functions, including digestion, circulation, and breathing. 

Anabolism is the process of building complex molecules from simpler ones, requiring energy input. This phase of metabolism is responsible for the synthesis of proteins, DNA, and other essential components necessary for cellular growth, repair, and maintenance. 

Energy Balance 

Metabolism plays a pivotal role in maintaining energy balance within the body. Energy balance refers to the equilibrium between the energy we consume through food and the energy we expend through physical activity and bodily functions. A well-functioning metabolism is crucial for achieving and maintaining a healthy weight, avoiding weight-related diseases, and preventing the incidence of diabetes.  

Basal Metabolic Rate (BMR) 

The basal metabolic rate (BMR) is the amount of energy expended at rest to sustain basic physiological functions. It accounts for the largest proportion of our daily energy expenditure. It is what people refer to as a “fast” or “slow” metabolism. Several factors influence BMR, including age, gender, body composition, and genetics. Understanding BMR is vital for developing personalized nutrition and exercise plans tailored to individual needs. 

Metabolism and Weight Management 

Metabolism plays a significant role in weight management. Dr. Fertig explains that a slow metabolism may make it more challenging to lose weight, as fewer calories are burned at rest. However, he also highlights that metabolism is a dynamic process that can be influenced by various factors, such as physical activity, muscle mass, and diet. 

 Factors Affecting Metabolism 

Numerous factors influence metabolism, including genetics, age, body composition, hormonal balance, and environmental factors. A doctor that understands human metabolism will often adopt a holistic approach to optimize metabolism. This could include engaging in regular physical activity, consuming a balanced diet, managing stress levels, and prioritizing quality sleep. These are all essential for maintaining a healthy metabolic rate. 

 Metabolism governs the way our bodies convert food into energy and maintain vital functions. By understanding the key factors that influence metabolism and adopting a holistic approach to lifestyle choices, we can optimize our metabolic rate and embark on a journey towards a healthier, more balanced life. 

Seeking the advice of a doctor is crucial for those struggling with weight gain and other metabolic-driven issues.  Patients trying to understand what is metabolism should find a qualified doctor like Dr. Brian Fertig, a New Jersey-based endocrinologist. He understands every part of the metabolic process and how it affects the body. He is also a noted author of “Metabolism & Medicine”, a comprehensive look at the ways the body’s metabolic processes impacts every part of wellness, from diabetes and weight gain to chronic age-related diseases.
