Key takeaways
- Your body burns calories through resting metabolism, digestion and movement.
- Resting metabolism typically represents 60–70% of total daily calorie burn.
- According to a 2021 Science study, metabolism stays steady from about 20 to 60.
- Muscle-building, daily movement, protein intake and quality sleep support metabolism naturally.
The most effective natural ways to boost metabolism are building muscle, moving more throughout the day, eating enough protein and sleeping well. No single trick dramatically changes your metabolic rate, but these habits add up over time.
Where Your Daily Calories Go
Total daily energy expenditure has three components.
- Basal metabolic rate (BMR): the calories your body needs to stay alive at rest, generally 60% to 70% of the daily total. Body size and muscle mass have the biggest influence here.
- Thermic effect of food (TEF): around 10% of calories go toward digesting meals. Protein has a much higher TEF than carbohydrates or fats.
- Activity: planned exercise and non-exercise activity thermogenesis (NEAT), the energy used by daily movement like walking, standing and household tasks.
Does Metabolism Really Slow Down With Age?
Not between your 20s and your 60s, according to the largest study of its kind. Published in Science in 2021, the research led by Herman Pontzer analyzed more than 6,400 people from 29 countries. After accounting for body size and composition, metabolism remained stable from roughly age 20 to 60 and then declined slowly at about 0.7% per year.
What usually changes in midlife is lifestyle: muscle mass slowly declines with inactivity, daily movement drops, stress rises and sleep suffers. All of these affect weight, and all of them can be improved.
Because muscle is more metabolically active than fat, maintaining muscle mass is one of the best ways to support a healthy resting metabolism over the years.
Natural Ways to Support Your Metabolism
Build and keep muscle
Include at least two strength sessions per week that work the legs, back, chest, shoulders and core.
Move more all day
Short walks, standing breaks and active hobbies raise NEAT, which can make a bigger difference than an occasional intense workout.
Eat enough protein
Protein supports muscle, increases fullness and uses more energy to digest. Spread it evenly across your meals.
Prioritize sleep
Seven to nine hours of sleep supports recovery, appetite balance and the energy to stay active.
Where Supplements Fit
Supplements can complement metabolism-friendly habits. Green tea catechins combined with caffeine have been studied for supporting thermogenesis, and chromium supports normal carbohydrate metabolism. If you take medication or are sensitive to caffeine, talk to your doctor first.
