Best Foods for Energy: 10 Practical Choices

Oats, beans and eggs are among the best foods for energy because they provide carbohydrates, protein or both as part of balanced meals.

Food supplies the fuel your body needs, but no single food guarantees alertness or fixes every cause of fatigue. For hydration ideas alongside meals, see the best drinks for energy.

What are 10 of the best foods for energy?

Alongside these 10 foods, use the hydration checker to consider whether you may need more fluids.

The order below is practical, not a proven ranking. A 2022 observational study of 4,563 women aged 65 and older linked closer adherence to a Mediterranean-style diet with more favorable fatigue and energy scores. It cannot establish that the diet caused those differences or that any one food relieved fatigue.

The portions below are examples for building meals and snacks, not tested doses for reducing fatigue. Your needs depend on your appetite, activity, age and health.

1. Oats

Oats provide carbohydrates that your body can use for fuel, as well as fiber. The fiber helps make oatmeal a more filling choice than a breakfast made mostly of refined carbohydrates. Adding protein or fat can make the meal more satisfying.

Start with about ½ cup of cooked oats and add plain yogurt, nuts or fruit. Increase the portion if you need a larger meal. The nutrition rationale for oats is well established, but direct evidence that oatmeal itself reduces everyday fatigue is limited.

2. Beans

Beans supply carbohydrates, fiber and plant protein, so they can contribute both fuel and staying power to a meal. They also contain iron, which your body needs to make hemoglobin, a protein that carries oxygen in the blood. Eating beans will not necessarily correct an iron deficiency.

Try ½ cup of cooked beans in a rice bowl, soup or salad. Pairing beans with a vitamin C source, such as tomatoes or bell peppers, helps your body absorb their plant-based iron. Evidence for beans as a stand-alone fatigue remedy is limited; they are useful as part of an overall balanced diet.

3. Eggs

Eggs provide protein and vitamin B12. B12 helps maintain healthy nerves and blood cells, although eating extra B12 will not automatically improve energy if you already get enough. Eggs contain little carbohydrate, so pair them with a carbohydrate food when you want a meal that supplies readily available fuel.

Have 1 egg with whole-grain toast, potatoes or fruit, adjusting the meal to your appetite. Cook eggs thoroughly. Eggs are a convenient source of protein and nutrients, but evidence that they specifically reduce fatigue in otherwise well-nourished people is limited.

4. Brown rice

Brown rice is a whole grain that supplies carbohydrates for fuel. It also contains fiber, which can contribute to fullness when the rice is part of a meal. White rice can provide fuel too; the choice does not need to be all or nothing.

Try ½ cup of cooked brown rice with beans, vegetables and a source of protein. In the observational study above, modeled substitution of whole grains for non-whole grains was associated with more favorable fatigue scores. That finding supports interest in whole grains, but it does not prove that brown rice itself prevents fatigue.

5. Potatoes

Potatoes provide carbohydrate, making them a useful food when you need fuel for daily activity or exercise. A potato eaten with its skin also provides fiber. Preparation matters: a baked or boiled potato offers a different meal from a serving of fried potatoes with salty toppings.

Use 1 small cooked potato as a starting portion, and add beans, eggs or yogurt for protein. Adjust the amount to your needs and preference. Potatoes are a practical carbohydrate source, but direct evidence that eating them improves everyday fatigue is limited.

6. Bananas

Bananas provide carbohydrates in a portable form. They are convenient when you want a snack that needs no preparation, including before or after activity. A banana can also be paired with protein or fat when you want a more substantial snack.

Try 1 medium banana with a small handful of nuts or a serving of plain yogurt. You can also slice it over oatmeal. Bananas supply fuel, but they are not uniquely proven to increase alertness or resolve fatigue; evidence for that specific claim is limited.

7. Plain yogurt

Plain yogurt supplies protein and, when made from dairy, vitamin B12. Protein helps make a meal or snack more filling, while B12 supports normal blood-cell and nerve function. Check the label because protein content varies among products; strained yogurts are often higher in protein.

Try about ¾ cup of plain yogurt with fruit or oats. If you avoid dairy, look for a suitable fortified alternative and check its protein content. Yogurt can help you meet nutrient needs, but evidence that it independently treats fatigue is limited.

8. Salmon

Salmon provides protein, vitamin B12 and unsaturated fats, including omega-3 fats. It can make a carbohydrate-based meal more substantial, while its B12 contributes to normal blood-cell function. It is a food choice, not a substitute for evaluation or treatment of a suspected deficiency.

Try a 3-ounce (85-gram) cooked portion with rice or potatoes and vegetables. In the observational study above, modeled substitution of fish for red and processed meat was associated with more favorable fatigue scores. That association does not show that salmon alone improves energy.

9. Nuts

Nuts supply unsaturated fats, some protein and fiber. They provide food energy in a compact form and can help make a fruit or grain snack more filling. Their carbohydrate content varies, so pair them with fruit or another carbohydrate food if you want that fuel as well.

A practical starting portion is 1 ounce (about 28 grams), eaten on its own or added to oatmeal or yogurt. Choose unsalted nuts if you prefer to keep the snack lower in salt. Nuts fit a balanced eating pattern, but direct evidence that they relieve fatigue on their own is limited.

10. Spinach

Spinach supplies folate and plant-based iron, nutrients involved in normal red blood cell formation. It is not a concentrated fuel source compared with grains or potatoes, so it works best alongside foods that supply carbohydrates, protein and fat. Its iron is also less readily absorbed than iron from animal foods.

Add 1 cup of raw spinach to a sandwich or salad, or use cooked spinach in an egg or bean dish. Tomatoes or peppers can help with absorption of plant-based iron. Spinach contributes nutrients, but evidence that it independently reduces fatigue is limited.

Which foods should you limit for steadier energy?

You do not have to eliminate sweets or refined grains. But if a pastry or sugary snack leaves you hungry soon afterward, try a more filling choice more often: fruit with nuts, yogurt with oats, or beans with a whole grain. Responses vary, and a sweet food does not necessarily cause an energy crash for everyone.

Processed meats and heavily salted packaged snacks can also crowd out more varied foods when they become regular meal choices. Replace them sometimes with beans, eggs, fish, vegetables or whole grains, rather than relying on a single replacement food. Alcohol and excessive caffeine can disrupt sleep, which can affect how energetic you feel the next day.

Who should be careful, and when should you see a doctor?

If you have diabetes, discuss substantial dietary changes with your care team, particularly if you use insulin or another medicine that can cause low blood sugar. People with kidney disease may need individualized advice about foods such as beans, nuts and potatoes. Avoid any food that causes you an allergic reaction.

If you take warfarin, keep your vitamin K intake consistent and speak with your prescriber before making major changes to foods such as spinach. Do not stop or change medication on your own. During pregnancy, or when a child has ongoing fatigue, ask a clinician for advice rather than relying on an energy-food list.

See a clinician if fatigue persists, worsens or interferes with daily life, or if it comes with symptoms such as unexplained weight loss or unusual bleeding. Seek urgent medical help for fatigue accompanied by chest pain, severe difficulty breathing or fainting.
