Fatigue manifests as lingering tiredness, exhaustion, weariness, lethargy, and listlessness, which renders you incapacitated to function at your optimum best. Everyone is bound to suffer from dissipated levels of energy from time to time, but constantly feeling fatigued for no apparent cause is a whole new level of debilitating.
Many people blur the lines between the two and equate their sporadic bouts of exhaustion and drowsiness stemming from a long day at work or a sleepless night as generalized fatigue. While feeling tired and sleepy is symptomatic of fatigue, this problem has other far-reaching social, physical, and psychological consequences.
Fatigue usually entails a prolonged feeling of apathy and demotivation along with the typical markers of physical, mental, and emotional exhaustion. This state is not categorized as a health condition unto itself, but as the symptom of some underlying issue.
It can set in as a response to intensive physical exertion or it can be psychosomatic in nature. But most cases of physical and mental fatigue occur in tandem. While physical fatigue is associated with unusually low levels of stamina and muscle weakness, mental fatigue makes it impossible to concentrate on the simplest of tasks and leaves you utterly indifferent and languished.
Most cases tend to resolve within a few hours or a day after giving your mind and body a much-needed break. To that end, you may reduce the intensity of your activity or catch up on some sleep.
However, if your level of exhaustion is unrelenting despite adequate sleep, stress management, proper nutrition, and physical activity, you may be suffering from chronic fatigue, which can hamper your ability to manage daily affairs to a significant degree.
Foods That Help Fight Fatigue
Here are 13 foods to re-energize yourself and fight fatigue.
1. Eat bananas
Bananas contain a good amount of potassium, which the body needs to convert sugar into energy.
Also, bananas are rich in many important nutrients, such as B vitamins, vitamin C, omega-3 fatty acids, omega-6 fatty acids, fiber, and carbohydrates, that help beat tiredness, dehydration, and other fatigue symptoms. (1)
Plus, the natural sugars, namely, sucrose, fructose, and glucose, in bananas are essential for quick energy boosts.
How to consume:
- Eat 1 to 2 bananas daily.
- You can also enjoy a banana in a shake or smoothie to keep your body hydrated and full of energy.
2. A cup of green tea can help
Sipping on a cup of refreshing green tea may also fight fatigue, especially exercise-related fatigue.
A 2018 study found that green tea extract improved fatigue associated with muscle damage and oxidative stress in athletes. (2)
A 2017 study in mice found that a polyphenol in green tea, epigallocatechin-3-gallate (EGCG), was able to prolong swimming time in mice in comparison with the placebo group. This suggests green tea may have anti-fatigue properties. (3)
To make a cup of green tea:
- Steep 1 teaspoon of green tea leaves in a cup of hot water for 5 minutes.
- Strain and add honey.
- Drink this tea two or three times daily.
Instead of green tea leaves, you can also use tea bags.
3. Chow down on pumpkin seeds
They are loaded with high-quality protein, healthy omega-3 fatty acids, and vitamin B1, B2, B5, and B6, as well as minerals including manganese, magnesium, phosphorus, iron, and copper. (4) All these nutrients work together to boost your immune system, provide energy, and fight symptoms of fatigue.
One of the amino acids in pumpkin seeds, tryptophan, may help fight emotional fatigue and promote better sleep. (5)
How to consume:
You can snack on a small handful of pumpkin seeds throughout the day to provide your body the beneficial fatigue-fighting nutrients. You can even switch to pumpkin seed butter as another way to get more pumpkin seed nutrients in your diet.

In one study, watermelon juice enriched with L-citrulline diminished muscle soreness perception from 24 hours to 72 hours after a race and maintained lower concentrations of plasma lactate after an exhausting exercise. (9) L-citrulline is a naturally occurring nonessential amino acid in watermelon.
Watermelon is rich in fatigue-fighting nutrients including potassium, vitamin C, antioxidants lycopene and beta-carotene, and iron. The next time fatigue comes calling and you need an instant boost of energy, have a slice of watermelon.
You can also make a healthy drink by blending some watermelon, a little honey and lemon juice, and water. Drink the juice after a workout to prevent signs of fatigue.

Another popular fatigue-busting food is walnuts. They are high in omega-3 fatty acids that can easily counteract fatigue symptoms. They can also help relieve symptoms of mild depression.

12. Munch on fibrous chia seeds
Chia seeds figure as a complete protein that is generously endowed with potassium, fiber, calcium, phosphorus, iron, and manganese. Given that a mere tablespoon of chia seeds contains 5 grams of fiber, munching on these power-packed seeds is a great way to up your daily fiber intake.
Chia seeds go well with a whole variety of dishes and can be a great value addition to your breakfast cereals, smoothies, juices, salads, etc.
13. Eat proteinaceous eggs
There is no end to the health benefits of eggs, which come packed with a rich supply of essential nutrients such as iron, zinc, and protein. Further enriched by a vital amino acid called leucine, eggs also help with muscle development and repair.
Another key component of this versatile wonder food is the high level of B vitamins that help with energy synthesis in the body. No wonder eggs have emerged as an undisputed breakfast favorite as a majority of people rely on them for an energetic start to their day.
Foods to Avoid
Avoid the following foods as they can deplete your energy levels.
1. Caffeinated drinks
The stimulating effect associated with caffeine is often short-lived and can even prove counterproductive in the long run. Despite the initial surge, your energy levels will eventually plummet lower than before.
If you can’t do without your regular dose of caffeine, try to minimize the damage by opting for healthier alternatives such as Bambu tea or coffee. These don’t contain the sugars and chemicals found in fizzy drinks and are a source of antioxidants.
2. Processed foods
Minimize your intake of processed foods as they contain high levels of sodium and saturated fat, both of which when taken in excess can cause negative health effects.
Sodium can have a dehydrating effect on the body, whereas an unhealthy amount of saturated and trans fats may make you feel sluggish. This category of food includes:
- Ready-to-eat meals
- Canned food
- Sugary breakfast cereals
3. Simple carbohydrates
Simple carbohydrates in the form of sugar and starch tend to break down more readily than their complex counterparts. Moderate intake of such simple carbohydrates can supply you with instant energy but it will come crashing down.
An excessively high sugar diet can render your energy levels quite erratic and unstable. Thus, it is essential that you don’t overdo their consumption but maintain a healthy balanced intake.
Common sugary foods to be kept in check include chocolates and sweets. Similarly, you might benefit from reducing your consumption of white flour, white bread, and many packaged snacks that are full of simple starches.

People are often convinced that they are doing everything to keep their energy levels up but miss out on some specific determinants that only a professional can help them out with.
Given that fatigue can be rooted in a whole gamut of treatable medical ailments, be the by-product of various drugs, or be the result of inactivity, you must work closely with your healthcare provider to first reach a comprehensive diagnostic evaluation.
Subsequently, a customized treatment approach can be developed to address the underlying factors contributing to fatigue and manage the varying symptoms that come with it. The healthcare provider will enumerate and discuss the possible benefits and harms of each therapeutic technique and medication.

- Was the onset of fatigue gradual or sudden?
- Have you gone through any significant life changes recently?
- Do you experience cyclical episodes of fatigue or has it become a constant state of being?

- Have you been feeling down or depressed lately?
Whether your fatigue is due to physical, mental, or emotional exertions, you may be able to fight it with some readily available foods.
Key foods will provide your body with all the essential nutrients, such as protein, fats, and complex carbohydrates, as well as vitamins and minerals, to function properly and fight symptoms of fatigue.
