An energy slump in the afternoon can ruin an entire day – especially in winter, when darkness comes early and fatigue weighs you down. The first instinct is to run for coffee, but it turns out there is a more effective and healthy way to restore your body’s strength: Food.
According to clinical dietitians interviewed by Real Simple, choosing the right foods can provide readily available energy, maintain a feeling of fullness, and prevent the crash that comes with an empty stomach.
How Nutrition Affects Energy Levels
Most of the calories in food serve as fuel for the body. The three macronutrients – carbohydrates, proteins, and fats – provide energy in different amounts and at different rates:
Carbohydrates are the fastest and most readily available source of energy.
Proteins and fats break down more slowly, providing longer-lasting energy.
Dietary fiber contributes to satiety and stable blood sugar levels.
The combination of these nutrients is key to maintaining steady energy throughout the day.
5 Foods That Give a Real Energy Boost
1. Oatmeal
Oatmeal is rich in complex carbohydrates that break down slowly – providing stable energy over time. It also contains soluble fiber that may help reduce cholesterol, as well as vitamins, minerals, and antioxidants.
Tip: Add a tablespoon of peanut butter, protein powder, or fresh fruit to enhance its nutritional value.
2. Bananas
Bananas are a natural, cheap, and readily available energy snack. They provide easily accessible carbohydrates and potassium – a mineral essential for muscle and nerve function.
To maintain fullness over time, it’s recommended to pair them with a source of protein and fat, such as nut butter.
3. Water
Yes, water contains no calories – but even mild dehydration can cause fatigue, weakness, and reduced concentration.
The body loses fluids through sweat, breathing, and urination, and if they are not replenished, you feel drained.
General recommendation: Drink daily at least half your body weight (in kilograms) in milliliters multiplied by 30–35, or simply make sure to stay properly hydrated throughout the day, especially if you are active.
4. Nut Butters
Peanut, almond, or cashew butter contains a winning combination of carbohydrates, protein, fat, and fiber – all contributing to energy and satiety.
It also provides important vitamins and minerals like magnesium, iron, and vitamin B6.
5. Eggs
Although relatively low in carbohydrates, eggs are rich in protein and quality fats that break down slowly and provide sustained energy.
They are also a good source of vitamin D, B vitamins, and iron – key components in preventing fatigue.
They can be paired with avocado toast or eaten as a hard-boiled egg snack in the middle of the day.
