How to Boost Metabolism

The collection of chemical processes that occur within living things in order to sustain life is referred to as metabolism. These reactions are responsible for converting food into energy, eliminating waste products, and supporting various physiological functions.

Metabolism can be broadly categorized into two types:

Catabolism: This involves breaking down complex molecules (such as carbohydrates, fats, and proteins) into simpler ones, releasing energy in the process.

Anabolism: This involves building complex molecules from simpler ones, requiring energy input.

The rate at which your body expends energy and carries out these metabolic processes is known as the metabolic rate. Basal Metabolic Rate (BMR) is the amount of energy expended while at rest in a neutrally temperate environment, and it accounts for a significant portion of the total daily energy expenditure.

If metabolism slows down, it can have various effects on the body and overall health including

  • Weight gain or difficulty in losing weight
  • Reduced energy expenditure can lead to feelings of fatigue and low energy levels. The body may not be efficiently converting food into the energy needed for daily activities.
  • Metabolism plays a role in regulating body temperature. A slower metabolism might impact the body’s ability to generate sufficient heat, potentially leading to sensitivity to cold.
  • A slow metabolism could be associated with imbalances in thyroid hormone levels, leading to symptoms such as fatigue, weight gain, and changes in mood.
  • Slowed metabolism can affect the efficiency of digestive processes, potentially leading to issues such as constipation or bloating.
  • A slower metabolism may result in a decrease in muscle mass, as the body may break down muscle tissue for energy more readily. This can impact overall strength and physical performance.

Best Ways on How to Boost Metabolism

Here are some ways to potentially boost your metabolism:

How to Boost Metabolism

How to Boost Metabolism – Regular Exercise

Physical activity, especially strength training and high-intensity interval training (HIIT), can increase muscle mass and boost metabolism.When in rest, muscle tissue burns more calories than fat.

Strength training and high-intensity interval training (HIIT) are two forms of exercise that can significantly contribute to boosting metabolism. Here’s how each type of training impacts metabolism:

Strength Training

Muscle Mass Increase: Strength training, also known as resistance or weight training, involves working against a resistance to build or maintain muscle mass. Your basal metabolic rate increases with your muscle mass (BMR). This is because muscle tissue is metabolically active and requires more energy at rest compared to fat tissue.

Afterburn Effect (EPOC): Strength training can create an “excess post-exercise oxygen consumption” (EPOC) effect. After a challenging strength workout, the body continues to burn calories as it works to repair and rebuild muscle tissues. This post-exercise calorie burn contributes to an elevated metabolic rate for a period after the workout.

Improved Insulin Sensitivity: Resistance training can enhance insulin sensitivity, helping the body use carbohydrates more effectively. This can contribute to better blood sugar control and metabolic health.

High-Intensity Interval Training (HIIT)

Caloric Burn: HIIT involves short bursts of intense exercise followed by periods of rest or lower-intensity exercise. This type of training can lead to a higher caloric burn compared to steady-state aerobic exercise. The intensity of HIIT elevates the heart rate and metabolism, promoting the consumption of more calories both during and after the workout.

Afterburn Effect (EPOC): Similar to strength training, HIIT can result in an afterburn effect. The body continues to burn calories post-exercise as it works to return to its resting state. This can contribute to an elevated metabolic rate for a period after the HIIT session.

Improved Oxygen Consumption: HIIT has been shown to improve cardiovascular fitness and increase the body’s oxygen consumption during and after exercise. This increased oxygen consumption contributes to a higher metabolism.

How to Boost Metabolism – Adequate Protein Intake

Protein has a higher thermic effect than fats or carbohydrates, meaning your body expends more energy digesting and processing it. Including sufficient protein in your diet can help support muscle growth and repair.

Here are some protein-rich foods to include in your diet:

Lean Meat

  • Chicken breast
  • Turkey
  • Lean cuts of beef (e.g., sirloin, tenderloin)
  • Pork loin


  • Salmon
  • Tuna
  • Cod
  • Tilapia


Eggs are a complete protein source and provide essential amino acids.

Dairy Products

  • Greek yogurt
  • Cottage cheese
  • Low-fat or skim milk

Plant-Based Proteins

  • Lentils
  • Chickpeas
  • Black beans
  • Quinoa
  • Tofu and tempeh

Nuts and Seeds

  • Almonds
  • Walnuts
  • Chia seeds
  • Pumpkin seeds
  • Sunflower seeds

Protein Supplements

  • Whey protein
  • Casein protein
  • Plant-based protein powders (pea, rice, hemp, etc.)

Lean Dairy

  • Low-fat or fat-free cheese
  • Low-fat or fat-free yogurt

How to Boost Metabolism – Stay Hydrated

Dehydration can slow down metabolism. Drink enough water throughout the day to support various metabolic processes.

How to Boost Metabolism – Eat Regular, Balanced Meals

Consuming regular meals helps maintain stable blood sugar levels, preventing the body from entering a state of energy conservation that can slow down metabolism.

How to Boost Metabolism – Adequate Sleep

Insufficient sleep has the ability to upset the hormonal equilibrium, influencing hormones that control hunger and possibly slowing down metabolism. Aim for seven to nine hours of good sleep every night.

How to Boost Metabolism – Green Tea

Caffeine is a naturally occurring stimulant that is found in green tea. Caffeine can temporarily boost metabolism by increasing the release of adrenaline. Adrenaline, also known as epinephrine, is a hormone that can stimulate the breakdown of fats, releasing them into the bloodstream for use as energy.

Green tea has thermogenic properties, meaning it can increase the body’s production of heat. This is partly due to the combination of caffeine and catechins, which may contribute to a slight increase in energy expenditure.

How to Boost Metabolism – Spicy food

Spicy foods, particularly those containing compounds like capsaicin found in chili peppers, have been associated with a temporary increase in metabolism. Here’s how spicy foods may contribute to this effect:

Thermogenic Effect

Capsaicin, the compound responsible for the heat in chili peppers, is known to have a thermogenic effect. The process through which the body produces heat is known as thermogenesis. When you consume spicy foods, capsaicin can temporarily increase the body’s temperature, leading to a short-term boost in metabolism.

Caloric Expenditure

The body expends energy to cool itself down after consuming spicy foods. This process, known as diet-induced thermogenesis, can result in a slight increase in calorie expenditure. The body may burn more calories as it works to regulate its temperature.

Appetite Suppression

Spicy foods, especially those containing capsaicin, may help reduce appetite. This can be attributed to the activation of receptors in the gastrointestinal tract, leading to feelings of fullness and potentially influencing food intake.

Fat Oxidation

Some studies suggest that capsaicin may enhance fat oxidation, meaning it can increase the body’s ability to burn fat for energy. This could contribute to a slightly higher metabolic rate.

How to Boost Metabolism – Cold Exposure

Exposure to cold temperatures may stimulate brown fat activity, which burns calories to generate heat. Activities like cold showers or spending time in a cold environment may have a positive impact.

How to Boost Metabolism – Manage Stress

Hormonal abnormalities based on by excessive stress may have an impact on metabolism. Include stress-relieving activities in your daily life, such as yoga, meditation, or deep breathing techniques.

How to Boost Metabolism – Avoid Extreme Diets

Very low-calorie diets or extreme diets can lead to muscle loss and a decrease in metabolism. Focus on sustainable, balanced eating habits.
