5 Natural Ways to Boost Metabolism and Burn More Calories

You can support your metabolism naturally by building muscle, eating enough protein and fiber, staying active, sleeping well and drinking water.

Genetics set most of your baseline, so think of these as small, steady helpers, not a fast fix.

Key takeaways

  • Harvard Health says your genetic makeup is the greatest determinant of your metabolism.
  • Building muscle helps, because muscle burns more calories than fat, even at rest.
  • Protein and fiber-rich foods take more effort to digest and help you feel full.
  • The NHS suggests 150 minutes of moderate activity a week plus strength work on at least 2 days.
  • Supplements and "metabolism boosters" have little evidence behind them.
  • Talk to your doctor if you have unexplained weight changes or symptoms.

What is metabolism, and what shapes it?

Metabolism is the process your body uses to turn food into energy. It keeps your heart beating, your lungs working and your cells repairing, even when you are resting.

Harvard Health states that your genetic makeup is the greatest determinant of your metabolism.

Other things that affect it

  • Muscle mass. Muscle burns more calories than fat, and it does so even at rest.
  • Age. Metabolism tends to slow as you get older, partly because muscle mass falls.
  • Body size. A larger body uses more energy.
  • Activity. Movement adds to your daily energy use.

This means you cannot completely change your metabolism, but you can support it. Small habits add up over months.

You will also see a lot of hype about "boosting" metabolism. Be careful with dramatic claims.

Way 1: Build muscle with strength training

Harvard Health explains that muscle burns more calories than fat, and unlike fat, it burns calories even at rest. Strength training can also lead to extra calorie burn after hard workouts.

The NHS suggests strengthening activities that work all the major muscle groups on at least 2 days a week.

  • Start with bodyweight moves such as squats, wall push-ups and step-ups.
  • Add light weights or resistance bands when they feel easy.
  • Rest for at least a day between sessions for the same muscles, as the NIDDK suggests.

Our guides on beginner strength training and strength training for weight loss show how to start.

Way 2: Eat enough protein and fiber

Harvard Health notes that protein foods, such as chicken, fish and Greek yogurt, can support metabolism, and that unrefined carbohydrates with fiber take longer to digest.

Both help you feel full, which makes eating well easier.

  • Include a protein at every meal.
  • Choose whole grains, beans and vegetables for fiber.
  • Do not cut your food too low. Very low intake can leave you tired and hungry.

Way 3: Move more through the day

Every bit of movement uses energy. The NHS suggests at least 150 minutes of moderate-intensity activity a week, or 75 minutes of vigorous activity, spread across 4 to 5 days or every day.

It also suggests reducing time spent sitting and breaking up long periods without moving.

  • Take a short walk after meals.
  • Stand up and stretch every hour.
  • Take the stairs when you can.
  • Use active errands, like walking to the shop.
  • Try a brisk walk, as in our walking guide.

Small movements count

NHS Better Health says even 10 minutes a day can make a difference. You do not have to do everything in one go.

Way 4: Protect your sleep

Poor sleep makes healthy habits harder. NHS Better Health says too little sleep makes you more likely to choose high-calorie foods and too tired to exercise or cook healthy meals.

The NIDDK adds that people who get too little sleep tend to weigh more than those who get enough.

  • Keep a steady bedtime and wake time.
  • Make your bedroom quiet, dark and cool.
  • Avoid caffeine late in the day and screens for an hour before bed, as the NHS suggests.

Read more in our guides on how many hours of sleep you need and the 30-minute wind-down routine.

Way 5: Stay hydrated, and use drinks wisely

Water supports every process in your body. The NHS suggests swapping sugary drinks for water, which lowers calories with no effort.

Harvard Health mentions that drinking around three cups of green tea a day may burn around 100 extra calories, and that caffeine in coffee and tea can give a small lift. These effects are small, and they do not replace food, movement and sleep.

  • Keep a water bottle nearby.
  • Choose water or unsweetened tea and coffee most of the time.
  • Be careful with energy drinks and high-caffeine products.

A week of metabolism-friendly habits

Here is how you could combine the five ways in a normal week.

  • Monday and Thursday: a 20-minute strength session with bodyweight moves.
  • Tuesday, Friday and Saturday: a 30-minute brisk walk or another activity you enjoy.
  • Every day: protein at each meal, vegetables at two meals, water through the day.
  • Every night: a steady bedtime and a wind-down routine.
  • Sunday: plan the week and prep a few basics.

This adds up to close to the NHS guideline of 150 minutes of moderate activity a week plus strength work on at least 2 days.

If you are new to exercise, build up slowly. Start with what feels comfortable and add a little each week.

What not to do

  • Do not crash diet. The NHS advises avoiding rapid weight loss through restrictive diets.
  • Do not skip meals. It can lead to more hunger-driven snacking.
  • Do not rely on supplements. The NCCIH says many weight loss supplements have not been tested for safety, and some contain hidden drugs.
  • Do not overtrain. Rest days matter. The NIDDK suggests at least 1 day of rest between muscle-group workouts.
  • Do not judge progress by one number. Track energy, strength and sleep too.

Our article on why the scale is not the whole story shows other ways to see progress.

When a slow metabolism is not the problem

Many people blame their metabolism when weight is hard to lose. Often, habits, sleep, stress or medicines play a bigger role.

In some cases, a medical condition can affect weight or energy. See your doctor if you notice:

  • Unexplained weight gain or loss.
  • Constant tiredness, feeling cold, or other new symptoms.
  • Changes in appetite that you cannot explain.
  • Weight changes after starting a new medicine.

A doctor can check for causes and suggest next steps. Do not try to fix a suspected medical problem with supplements.

Why weight loss can feel slow

Many people say, "my metabolism is slow". Sometimes that is true. More often, several small things add up.

  • Portions creep up. Over time, plates and snacks get larger without us noticing.
  • Drinks add calories. Sugary drinks and juices are easy to overlook.
  • Activity drops. Sitting for long periods lowers daily energy use.
  • Sleep suffers. Poor sleep can push you toward high-calorie foods, as NHS Better Health notes.
  • Muscle falls with age. Without strength work, muscle can decline over the years.

A short food diary and a look at your daily movement often reveal where the gaps are.

Focus on what you can change

You cannot swap your genes, but you can add movement, build muscle, sleep well and eat balanced meals.

Over months, those habits can make a real difference to how you feel and how your body responds.

A first strength session you can do at home

If you are new to strength work, this simple session takes about 20 minutes. Do it twice a week, with a rest day between.

  • Warm up: march on the spot and roll your shoulders for two minutes.
  • Sit-to-stand: 8 slow repetitions from a sturdy chair.
  • Wall push-up: 8 slow repetitions.
  • Glute bridge: lie on your back with knees bent and lift your hips, 8 repetitions.
  • Step-up: 8 on each leg on a low, stable step.
  • Cool down: walk slowly and stretch your legs gently.

Repeat the circuit twice if it feels comfortable. Increase repetitions or add a light weight over the coming weeks.

Stop if you feel pain. If you have a health condition, or you are unsure about your form, speak to your doctor or a qualified trainer.

Metabolism myths to skip

  • "Eating very little speeds up fat loss." Very low intake can leave you tired and struggling to keep going. The NHS advises against rapid weight loss through restrictive diets.
  • "A special food or spice melts fat." Foods can support your plan, but none works alone.
  • "Supplements will boost your metabolism." The NCCIH says acai berry, bitter orange and green tea supplements have not been shown to produce meaningful weight loss in scientific studies.
  • "It is all my age or my genes." These matter, but habits like strength training, movement and sleep still help.

Our article on fat burners covers supplements in more detail.

Recap: the main points

  • Genetics set most of your metabolism, but habits still help.
  • Build muscle with strength training on at least 2 days a week.
  • Eat protein and fiber, and move often through the day.
  • Protect your sleep and drink water.
  • Be careful with supplements and quick-fix claims.

Boosting metabolism: frequently asked questions

You can support it. Building muscle, staying active, eating enough protein and fiber and sleeping well all help, though genetics are the biggest factor.

No food dramatically boosts metabolism. Harvard Health notes protein foods and fiber-rich carbohydrates can support it, and that green tea and caffeine may have a small effect.

Building muscle can help, since muscle burns more calories than fat, even at rest. The NHS suggests strength work on at least 2 days a week.

Metabolism tends to slow with age, partly because muscle mass declines. Strength training and regular movement can help.

Evidence is weak. The NCCIH says acai berry, bitter orange and green tea supplements have not been shown to produce meaningful weight loss.

See your doctor if you have unexplained weight gain or loss, constant tiredness, or other symptoms that worry you.
