Having a high or fast metabolism is (for the most part) great news. Essentially, it means your body burns energy from food at a faster rate than those with a slower metabolism.
In laymen’s terms, metabolism is the digestive process that turns food into fuel. This energy is then used by your body to function; think hormones, bone, skin, nails, flesh, neurotransmitters, and healthy organs – they all need energy.
If you’ve heard that the speed of your metabolism is genetic, there’s some truth to this. A study from 2001, which has yet to be challenged, discovered that baseline metabolism is determined at birth. What this means is that, yes, you can be born with a slow metabolism, but it doesn’t have to stay this way – which is particularly comforting news for women over 30. After entering your thirties your RMR (Resting Metabollic Rate; the amount of energy – and therefore number of calories – your body requires each day to perform basic functions) decreases at a rate of 2-3 per cent per decade, mainly due to inactivity and muscle loss.
To reverse a sluggish metabolism – and lose excess weight that’s often the result of this – you need to take a holistic approach. If you simply slash your calories, you’re at risk of dialling down your metabolism further.

Your high metabolism crib sheet
1. Schedule in exercise
Exercise doesn’t just burn calories—it actually changes your DNA to boost your metabolism immediately.
Experts recommend up to an hour to see these benefits. To make absolutely sure you squeeze in these sweat sessions, schedule them ahead of time.
2. Strength train
Muscle is a fat-burning powerhouse, so stick to your strength-training routine. Aim for 120 minutes of strength sessions a week: try a total-body workout circuit with weights to build muscle, or do a TRX workout the next time you hit the gym.
3. Do cardio
So you’ve swapped your running for a gym workout and are feeling pretty pleased about it. Well, don’t celebrate just yet. Cardio is crucial for keeping your metabolism running smoothly. In one study, researchers found that cyclers increased their metabolism for 14 hours after a tough 45-minute workout.
“If you do just two to three vigorous bouts of exercise per week for 45 minutes, you could lose a pound of fat every two weeks from the combination of calories expended during exercise plus what you burn afterward,” says study author David Nieman, a doctor of public health and professor of exercise science at Appalachian State University.
If you add your total cardio time (3 x 45-minute sessions) to your strength training time (120 minutes) it totals 4.25 hours. That’s still less than a week’s worth of skipping lunch. We say, take a lunch break and work on your body, not your inbox this week.
4. Eat breakfast
After a long night of fasting, your body needs fuel to rev up its metabolism.
Skipping breakfast can slow down your body’s ability to burn fat as it tries to conserve energy, so make sure you eat a healthy breakfast within an hour of waking up.
5. Don’t skip meals
You might think that passing on dinner would translate to a slimmer waistline, but it does just the opposite. Skipping meals can make your body think it’s starving so it stores extra calories instead of burning them.
Eat up to six small meals a day to fend off hunger, keep blood-sugar levels steady, and help your metabolism function properly.
Stress can do more than drive you crazy — it can actually slow down your digestion and thwart any goals of having a high metabolism.
The stress hormone cortisol is the culprit: When levels are too high, it inhibits your body’s ability to burn fat. Take a few moments to breathe deeply or flow through a calming yoga sequence to keep your metabolism in check.
