"My metabolism is just too slow." – hardly any term is used as frequently in relation to diet and body weight as metabolism. At the same time, teas, spices, fasting cures, or certain foods promise to "jump-start" it.
But can the metabolism actually fall asleep? Do muscles burn more energy even while on the sofa? And are there foods that get our body to burn fat? Time to take a closer look at some metabolism myths.
Metabolism refers to the sum of all chemical processes in our body. Nutrients are absorbed, converted, built up, stored, or broken down.
This is by no means just about body weight. Metabolic processes take place virtually everywhere: when cells provide energy, when proteins are built, when the liver processes substances, or when the body forms new cellular components.
When people talk about a "fast" or "slow metabolism" in everyday life, however, they usually mean something else: How much energy does my body consume?
Even if we were to spend an entire day on the sofa, our body would have a considerable energy requirement. After all, the heart, brain, breathing, circulation, body temperature, and numerous other processes keep running.
The total energy expenditure differs from person to person. Body size and body composition play a role, as do physical activity, age, biological factors, and various hormonal influences.
People do indeed differ in how much energy they consume. However, a lower energy expenditure does not automatically mean that something is wrong with the metabolism.
For example, a smaller body usually requires less energy than a larger one. Fat-free mass also influences resting energy expenditure. Two people can therefore have different energy requirements, even though both are healthy.
An unusually low or high energy turnover can also have medical causes in certain cases. Thyroid hormones, for instance, are involved in regulating energy metabolism. An underactive thyroid can affect energy consumption – but it is not the explanation for every weight gain.
Muscle tissue requires energy even at rest. People with more fat-free mass therefore generally have a higher resting energy expenditure.
However, the effect of additional muscle mass is sometimes exaggerated. Strength training does not turn the body into a "calorie furnace" that suddenly burns huge amounts of energy.
Nevertheless, strength training is useful: it helps build or maintain muscle mass and physical performance. Especially as we age, maintaining muscle mass becomes increasingly important.
When thinking about energy consumption, many people first think of jogging, the gym, or other sports. But movement outside of training also counts.
Shopping on foot, climbing stairs, cycling, gardening, or getting up throughout the day – all these activities require energy. How active we are in daily life can therefore have a significant impact on our total energy expenditure.
Exercise is therefore not the only way to get more movement into your day. Regular everyday activity can make a significant difference.
The term "energy-saving mode" sounds more dramatic than it actually is. The metabolism does not simply switch off during a diet.
However, energy expenditure can decrease during weight loss. One reason for this is simple: a lighter body requires less energy. At the same time, when losing weight, both fat mass and fat-free mass can be lost.
In addition, the body can partially adapt to reduced energy intake and lower body weight. This phenomenon is known as adaptive thermogenesis or metabolic adaptation.
This can contribute to weight loss slowing down after a while or reaching a plateau. However, it does not mean that the metabolism is "broken."
Individual foods or ingredients can have a minor short-term impact on energy expenditure. However, this does not create a significant "turbo" effect for the metabolism. Body composition and physical activity are significantly more important for long-term energy consumption.
That is not necessarily the case. Larger bodies generally require more energy to maintain than smaller ones. Body weight is also influenced by numerous biological, behavioral, and environmental factors.
Eating more frequently does not automatically cause the body to consume significantly more energy throughout the day. How often someone eats can be tailored to personal preferences and needs.
The body does not have a metabolic clock that suddenly switches to fat storage at 6 PM. The long-term energy balance is essential for body weight. However, the timing and composition of meals can influence aspects such as sleep, appetite, and eating behavior.
During weight loss, energy expenditure can drop, and the body can partially adapt to the changed situation. However, this does not mean that the metabolism is permanently "destroyed."
The idea of a metabolism switch that you can turn to "fast" in the morning with a certain drink or food is tempting – but too simple.
It makes much more sense to look at factors that can actually be influenced. Regular physical activity increases energy expenditure during movement. Strength training supports the maintenance and building of muscle mass. At the same time, a varied, balanced diet provides the body with the necessary nutrients.
Getting enough sleep is also part of a health-conscious lifestyle. Lack of sleep can affect appetite, eating behavior, and physical performance – even if one shouldn't say that sleep simply "speeds up" the metabolism.
Weight and energy consumption are influenced by many factors. Nevertheless, significant changes can sometimes be a reason to take a closer look.
Unexplained weight gain or loss should be medically clarified, especially if other symptoms appear. These can include, for example, pronounced fatigue, unusual sensitivity to cold or heat, heart palpitations, severe thirst, or other new symptoms.
There can be very different reasons for this. Metabolic and hormonal diseases such as thyroid dysfunction or diabetes are among the possibilities – but they cannot be diagnosed by yourself based on individual symptoms.
Our metabolism is not an engine that we can speed up or slow down at will with a specific food. It comprises a complex network of processes that keeps our body alive 24/7.
Anyone looking to influence their energy expenditure does not need a "metabolism booster." Regular exercise, maintaining muscle mass, and a balanced lifestyle are the much more sensible levers to pull.
Metabolism refers to the sum of all chemical processes in the body in which substances are absorbed, converted, built up, stored, or broken down. This also includes the provision of energy.
People differ in their energy expenditure. Body size, body composition, activity, and other biological factors play a role. A comparatively low energy expenditure does not automatically mean that a disease is present.
There is no simple metabolic turbo. Physical activity increases energy expenditure, and muscle mass contributes to resting energy expenditure. Individual foods, on the other hand, do not have a large long-term effect on energy expenditure.
When losing weight, energy requirements drop, partly because a lighter body requires less energy. In addition, there can be a certain metabolic adaptation. However, the metabolism is not simply "broken" by this.
Muscle tissue requires energy even at rest. More fat-free body mass is therefore associated with a higher resting energy expenditure. The additional energy expenditure from individual kilograms of muscle mass should not be overestimated, however.
There is no set time after which food is automatically stored as body fat. The long-term energy balance is decisive for weight development. The timing and composition of meals can still influence other aspects like appetite, eating behavior, and sleep.
Thyroid hormones are involved in the regulation of energy metabolism. An overactive or underactive thyroid can therefore affect energy consumption, among other things, and should be medically clarified and treated.
