Lifestyle factors that affect your energy levels

Lifestyle factors that affect your energy levels

21 Oct 2021

Energy serves as vital fuel for our body. We use it to go about our daily activities, facilitate all our bodily functions such as breathing, digesting food and keeping warm, and to support growth and repair of muscles.

How does our body create energy?

The energy in our body is composed of carbohydrates, proteins and fats that are broken down by our digestive system (1). Carbohydrates turn into glucose, proteins turn into amino acids, and fats turn into fatty acids. These are absorbed by our blood cells where they become adenosine triphosphate or ATP, which is what our body needs to work.

However, there are a lot of factors that can affect how much energy and endurance we generate to go about our daily activities.

Energy and endurance

Factors that affect body energy

The following are some factors that affect the energy we have:


A balanced and healthy diet includes being able to eat from the five food groups every day. These groups include:

  • Vegetables and legumes
  • Fruits
  • Grains and cereals
  • Animal products such as lean meats, poultry, fish, chicken, eggs, and tofu
  • Dairy products such as milk, cheese, and yoghurt (2).

Eating the right kind and amount of food will give the body the energy it needs. This is because many important nutrients that support and maintain energy production can be found in what we eat.

These include iron, which can be found in red meats, fish, eggs, and wholemeal pasta (16), and magnesium which can be found in spinach, legumes, and nuts (17).

Iron helps maintain energy levels by assisting in many physiological processes such as metabolism, oxygen transport, and DNA synthesis, among others (3). Bear in mind that iron should only be taken if prescribed by your doctor.

Magnesium, on the other hand, is vital in energy production as it stabilises the enzymes our body needs for the generation of ATP. Magnesium can maintain and support energy levels.


Exercise helps build more energy and endurance. Besides boosting your stamina, how much you exercise may affect how much energy you have (13). A bit of exercise pushes your body to produce more mitochondria inside the cells of your muscles. Mitochondria turn glucose into energy. Having a greater number of them in your cells boosts your energy. In addition, being physically active also improves the circulation of oxygen, which allows your body to make better use of the energy.

However, it can be useful to balance the energy we produce and the energy we use up as the body burns more energy when it is active (5). If the body uses more energy than it can produce, whether through exercise, or in going about our other daily activities, we may end up fatigued or tired.

Taking in vitamins that support energy production such as vitamin C, vitamin B-complex and vitamin B12 can help boost energy levels to avoid this from happening.

Vitamin C helps maintain energy levels by breaking down fatty acids and turning them into energy (6). Vitamin B-complex releases energy from the fat and carbohydrates in our body (7). Vitamin B12 maintains energy levels by converting carbohydrates into glucose (8).

Alongside a balanced diet, a vitamin subscription personalised to your needs can help increase your energy needed for daily activities.

Good quality sleep

Sleep is as important as having a healthy diet and leading an active lifestyle.

Energy and endurance

When you sleep at night you go through non-REM (rapid eye movement) sleep, and REM sleep (15). During the final phase of non-REM sleep, also called deep sleep, or slow-wave sleep, the body repairs itself. During this period your body creates more ATP, boosting your energy levels (14).

On the other hand, poor quality of sleep can have an impact on our body’s energy levels (10). Sleep loss affects the quality of our energy and our performance during the day. When someone is sleep deprived, some tasks may require more energy than usual, and the ability of the body to overcome this can be limited (9).

Incorporating energy boosting vitamins into your diet can help boost energy when you are having trouble getting sleep.

Ashwagandha is an Indian herb that has a wide variety of benefits. It supports physical endurance and relieves symptoms of mild anxiety. This can help improve energy levels and normalise cortisone levels for stress management (11).

Taking acetyl L-carnitine may also help replenish energy levels. This nutrient maintains energy levels by transporting long-chain fatty acids into the mitochondria, the cell’s powerhouse13.Fatigue can be as a result of high or low blood pressure, heart and other chronic diseases, alcohol consumption, poor diet and other lifestyle risk factors13.
