What is Metabolism?
Metabolism is the process of converting food into energy within the human body. It combines oxygen with calories to fuel numerous bodily functions, such as:
- Digestion
- Breathing
- Circulating blood
- Repairing and growing cells
- Body temperature regulation
- Hormone regulation
Factors that influence the body’s metabolic rate (BMR) — the speed of its metabolic processes — include age, gender, muscle mass vs. fat mass, hydration, activity level, and body size.
During periods of catabolism (lower calorie intake), the body breaks down tissues to use for energy. When in anabolism, the body builds new tissues.
Common Myths About Metabolism
It’s helpful to understand the common myths linked to metabolism, such as:
- Metabolism doesn’t change with age
- Thin people have higher metabolisms
- We can’t control our metabolic rate
- Genetics determine body weight
- Eating at night slows metabolism
- Diet and other lifestyle changes don’t alter metabolism
- Skipping meals boosts metabolism
The truth is that making lifestyle (including dietary) changes may influence metabolic rate, body weight, and overall health and well-being.
Key Nutrients That Support Metabolism
Key nutrients that support a healthy metabolism include:
Protein
Protein plays a critical role in muscle building and repair, which boosts metabolic rate. Protein also has a relatively high energy requirement for digestion (the thermic effect of food, or TEF). Studies confirm that protein increases energy expenditure and fat oxidation.
Examples of protein-rich foods include fish, seafood, chicken, lean meats, eggs, tofu, legumes, nuts, seeds, dairy foods, and protein supplements.
Fiber
Fiber promotes digestion and helps stabilize blood sugar levels, which can prevent metabolic slowdowns. Fiber passes through the digestive system, contributing to TEF, but isn’t fully absorbed by your body. It also promotes satiety, which aids in weight management. Fiber-rich foods include vegetables, fruits, whole grains, nuts, seeds, and legumes.
Healthy Fats
Heart-healthy omega-3 fatty acids and their anti-inflammatory properties also support a healthy metabolism during exercise and at rest. Foods rich in omega-3s include fatty fish (salmon, mackerel, sardines, tuna, etc.) chia seeds, walnuts, and flax seeds.
Vitamins and Minerals
Micronutrients shown to benefit metabolism rates include:
- B vitamins aid in creating energy from foods
- Iron: used for oxygen transport through the blood, optimizing energy
- Magnesium: needed for more than 300 enzymatic reactions linked to energy production
- Vitamin C: involved in energy production via beta-oxidation
- Zinc: required for catalytic activity of enzymes and cell metabolism
Foods loaded with energy-producing vitamins and minerals include nuts, seeds, beans, lean meats, seafood, eggs, dairy, leafy greens and other vegetables, fruits, whole grains, and dark chocolate.
Top Metabolism-Boosting Foods
Some of the most effective metabolism-boosting foods include:
Green Tea
Green tea is rich in antioxidants, particularly epigallocatechin gallate (EGCG), which may support fat oxidation and metabolic rate. The caffeine in green tea also stimulates thermogenesis, increasing energy and calorie expenditure.
Chili Peppers
Capsaicin is a component in chili peppers that may contribute to energy expenditure and support metabolic rate fat loss. Add chili peppers to any favorite dish to spice it up and burn more calories.
Coffee
Caffeine in coffee may stimulate the central nervous system, potentially supporting metabolic rate, thermogenesis, and fat metabolism.
However, it’s important not to overconsume coffee to avoid stress on the adrenal glands. Coffee recommendations for healthy adults are up to 400 milligrams of caffeine daily. Pregnant and breastfeeding women should ask their doctor about safe amounts of caffeine.
Ginger
Ginger is a spice known for its effects on thermogenesis, satiety, fat reduction, anti-inflammatory properties, and efficient digestion, which all play important roles in supporting a healthy metabolism.
Whole Grains
The high fiber content of whole grains enhances metabolism efficiency by slowing digestion, increasing energy expenditure via the TEF, and boosting satiety. Add fiber-rich oats, brown rice, wild rice, barley, quinoa, and other whole grains daily.
High-Protein Foods
Metabolism-boosting, satiating, high-protein foods in a metabolism-boosting menu include chicken, lean meats, turkey, legumes, tofu, eggs, fish, seafood, dairy or plant-based dairy alternatives, nuts, and seeds. These foods increase satiety and enhance calorie burning via thermogenic effects.
Water
Proper hydration is important to maintaining a healthy metabolic rate, as even mild dehydration can hinder metabolism. Drink water often. General fluid requirements are 16 cups for men and 12 cups daily for women.
Apple Cider Vinegar
Apple cider vinegar may enhance metabolic function and blood sugar regulation.
Some studies suggest that drinking apple cider vinegar for 4-12 weeks may influence markers like body weight, body mass index (BMI), body fat, blood sugar, cholesterol, and triglyceride levels.
Dark Leafy Greens
Dark leafy greens, including spinach, Swiss chard, and kale, are loaded with magnesium and iron, key nutrients supporting red blood cell production and optimal energy levels.
Citrus fruits
Citrus fruits, such as oranges, grapefruit, and kiwi fruit, are packed with metabolism-boosting vitamin C and satiating fiber. Strawberries, red peppers, broccoli, Brussels sprouts, and tomato juice are other good sources of vitamin C.
Lifestyle Factors that Influence Metabolism
A nutritious diet isn’t the only factor that keeps your metabolic rates high. Other lifestyle habits that have a beneficial influence on metabolism include:
Exercise
Regular exercise increases metabolic rate by supporting metabolism, boosting muscle maintenance and growth, and increasing total daily energy expenditure. Strength training increases lean body mass and resting metabolic rate, while high-intensity interval training (HIIT) boosts metabolism post-exercise (excess post-exercise oxygen consumption, or EPOC).
Sleep
Many of us don’t get the recommended amounts of sleep (at least 7 hours per night for adults), which can affect metabolic efficiency and lead to weight gain. Establish a regular bedtime schedule and routine to maximize sleep quality and overall well-being.
Stress Management
Ongoing stress can elevate cortisol levels, which tends to negatively impact metabolism. Stress-management techniques like meditation, yoga, mindfulness, massage, outdoor time, and regular exercise should be considered to keep stress levels in check and boost energy.
Meal Timing and Frequency
Some research suggests that reducing meal frequency can lead to irregular eating patterns that may impact weight gain, hunger, and metabolic disturbances. Therefore, effectively planning meal timing and frequency can optimize metabolic rate for improved health.
Consuming smaller, more frequent meals at regular time intervals throughout the day may maximize metabolic balance.
Potential Pitfalls: Foods and Habits That Slow Metabolism
Foods and habits that may actually slow down metabolism include:
Refined Carbohydrates and Sugary Foods
Consuming added sugars and refined grains can lead to insulin resistance and metabolic slowdowns. Limit or avoid sodas and drinks containing added sugar, white bread, pastries, and sweet treats.
Highly Processed Foods
Whole foods rich in fiber, protein, or heart-healthy fats have a more favorable effect on metabolism than ultra-processed foods. Choose foods that haven't undergone processing, such as fresh fruits, vegetables, whole grains, legumes, nuts, and seeds. Opt for fresh or frozen meats instead of regular bacon, sausage, hot dogs, and other highly processed meats.
Skipping Meals
There is a misconception that skipping meals boosts metabolism, but the reality is that meal skipping can actually slow down metabolic rate and lead to overeating at the next meal.
Some research suggests that skipping breakfast may be associated with obesity, and late lunches may affect weight management.
Some studies suggest that fasting for 36-48 hours may decrease energy expenditure by 10% and that prolonged daily calorie restriction may reduce energy expenditure and increase appetite. Keep consistent meal schedules unless you’re fasting for medical reasons.
How to Incorporate Metabolism-Boosting Foods into Your Diet
Incorporate metabolism-boosting foods into your daily routine using the following meal ideas:
Meal Ideas and Examples
- Breakfast: Oatmeal made with plant milk and chia seeds, berries or citrus fruits, eggs, and green tea
- Snack: Fresh vegetables dipped in hummus
