Factors influencing metabolism


Your genetic makeup plays a significant role in determining your metabolism. Some people are naturally blessed with a faster metabolic rate, allowing them to burn calories more efficiently. However, if your genes predispose you to a slower metabolism, you may find it more challenging to lose or maintain weight. While you can’t change your genes, understanding this factor can help you make lifestyle choices that support a healthy metabolism.


As you age, your metabolism tends to slow down. This gradual decrease in metabolic rate is primarily due to a decline in muscle mass and a decrease in physical activity levels. To combat this natural decline, it becomes essential to engage in regular exercise and make mindful dietary choices as you get older.


There are metabolic differences between males and females. On average, men tend to have a higher metabolic rate than women. This is because men generally have a higher proportion of lean muscle mass, which requires more energy to maintain compared to fat mass. However, individual variations exist, and factors like body composition and physical activity level can influence metabolic differences between genders.

Body composition

Your body composition, including the ratio of muscle to fat, affects your metabolism. Muscle tissue is more metabolically active than fat tissue, meaning it burns more calories at rest. Therefore, individuals with a higher proportion of muscle mass tend to have a higher basal metabolic rate (BMR). Regular strength training exercises can help increase muscle mass and boost your metabolism.

Physical activity level

Your level of physical activity directly affects your metabolism. Engaging in regular exercise, whether it’s cardiovascular activities or weightlifting, can increase your metabolic rate both during and after your workout sessions. Additionally, incorporating more movement into your daily routine, such as taking the stairs instead of the elevator or going for a walk, can help keep your metabolism active throughout the day.

Understanding metabolism

Introduction to metabolism

Metabolism refers to the complex biochemical processes that occur within your body to convert food and drinks into energy. This energy is essential for your body to perform various functions, such as breathing, pumping blood, and maintaining body temperature. Metabolism consists of two main components: catabolism, the breakdown of substances to release energy, and anabolism, the synthesis of substances to create new cells and tissue.

Basal metabolic rate

Your basal metabolic rate (BMR) is the number of calories your body burns at rest to maintain basic bodily functions. It represents the energy needed for essential processes like breathing, circulating blood, and regulating body temperature. BMR is typically influenced by factors such as age, gender, genetics, and body composition. While you can’t significantly alter your BMR, certain lifestyle choices can help optimize your overall metabolic rate and calorie expenditure.

The thermic effect of food


The thermic effect of food (TEF) refers to the energy expended by your body to digest, absorb, and process the food you consume. It contributes to a small percentage of your total daily energy expenditure. Different macronutrients have varying thermic effects, with protein having the highest TEF, followed by carbohydrates, and then fats.

Effect on metabolism

TEF can slightly boost your metabolism as your body expends energy to digest and process the food you eat. However, the impact of TEF on overall calorie expenditure is relatively small compared to other factors like physical activity and basal metabolic rate. Nevertheless, incorporating foods with a higher thermic effect into your diet can still be beneficial for weight management.

Foods with high thermic effect

Certain foods are known to have a higher thermic effect, meaning they require more energy for digestion and absorption. Protein-rich foods like lean meats, fish, eggs, and Greek yogurt have a higher TEF compared to other nutrients. Fiber-rich foods, such as whole grains, legumes, and berries, also have a slightly higher thermic effect. By incorporating these foods into your diet, you can subtly boost your metabolism.

Metabolism-boosting nutrients


Caffeine is a natural stimulant found in various beverages like coffee, tea, and energy drinks. It is known to slightly increase metabolism by stimulating the central nervous system.

Drinking green tea regularly or taking green tea extract supplements may have a modest positive effect on your metabolism.

Omega-3 fatty acids

Omega-3 fatty acids, commonly found in fatty fish like salmon and sardines, have numerous health benefits, including a potential role in boosting metabolism. Research suggests that omega-3 fatty acids can increase fat metabolism, improve insulin sensitivity, and reduce inflammation. Incorporating foods rich in omega-3 fatty acids into your diet can support a healthy metabolism.


Iron is an essential mineral that plays a vital role in various bodily functions, including metabolism. Iron is necessary for the production of hemoglobin, a protein in red blood cells that carries oxygen throughout the body. Insufficient iron levels can lead to a decreased oxygen-carrying capacity, which can negatively affect metabolism. Ensure you include iron-rich foods like lean red meat, spinach, and legumes to support optimal metabolism.
