What Foods Make You Tired and Sluggish?

What Foods Make You Tired and Sluggish?

posted 2023 Dec by

We've all been there before: that post-lunch lethargy where you struggle to keep your eyes open in the mid-afternoon. It's a common experience, but have you ever stopped to consider what might be causing it? 

While it's easy to blame it on a busy schedule or lack of sleep, the truth is that your diet could play a significant role in your energy levels. As you know, food is the fuel that keeps our bodies running. 

However, not all foods are created equal when providing us with sustained energy. Some foods can actually make us feel more tired and sluggish

But how does this work? It all comes down to how our bodies process different types of nutrients, particularly carbohydrates.

Here at L’Evate You, we’re committed to helping you experience more energy from the inside out. In this guide, we’re going to cover all the foods that can make you feel tired and sluggish. 

We’ll also talk about a few ways to fight fatigue and stay sharp for the entire day. Let’s get started right away before that dreaded slump kicks in!

How Do Carbohydrates Affect Energy Levels? 

Carbohydrates serve as the primary source of energy for our bodies. They’re broken down into glucose, which is used by our cells as fuel. But it's essential to know that not all carbs are created equal.

Simple carbs, like those found in sugary drinks, sweets, and processed foods, are quickly absorbed by your body. This rapid absorption causes a spike in your blood sugar, known as a sugar rush. It might feel good at the moment, but it's often followed by a rapid drop in blood sugar that can leave you feeling tired and sluggish.

On the other hand, complex carbs found in foods like whole grains, fruits, and vegetables are digested at a slower rate. This slower digestion results in a gradual release of energy, helping to keep your blood sugar levels stable and your energy levels sustained.

The glycemic index (GI) is a helpful tool in understanding this process. It measures how quickly a food causes your blood sugar to rise. Foods with a high GI can cause a rapid increase in blood sugar, followed by a swift drop, leading to feelings of tiredness and lethargy.

So, if you're reaching for a sugary snack or drink for a quick energy boost, you might want to think twice. While it might give you a quick pick-me-up, it's likely to leave you feeling even more tired in the long run. Instead, consider opting for foods with a lower GI for sustained energy throughout the day.

What Foods Can Make You Feel Tired and Sluggish? 

It's a common misconception that food always energizes us. While it's true that food provides us with the fuel we need to function, certain foods can actually drain our energy rather than replenish it. 

Here's a closer look at some of the common culprits that may be sabotaging your vitality:

White Bread

White bread is a prime example of a food high in refined carbohydrates. During the refining process, the grain is stripped of its fiber-rich outer shell and nutritious inner germ, leaving behind a product that's rapidly absorbed by the body. This quick absorption can cause a spike and subsequent drop in blood sugar levels, leaving you feeling tired and sluggish.

High-Sugar Cereals

These breakfast staples may seem like a quick and convenient way to start your day, but they can often be loaded with added sugars. Much like white bread, the high sugar content can cause a rapid rise and fall in your blood sugar levels, leading to a mid-morning energy crash followed by an afternoon slump.

Fried Foods

Foods that are fried are typically high in fats. High-fat foods are digested more slowly by the body, leading to a feeling of fullness that can induce sleepiness. Additionally, the energy your body uses to process these fats can leave you feeling drained, hindering your productivity and overall vigor.

Heavy Meals

Have you ever noticed how you feel like taking a nap after a big meal? This phenomenon, often referred to as a "food coma," happens because your body has to work harder to digest large amounts of food. This can divert blood flow from your brain to your digestive system, causing feelings of tiredness.

Sugary Drinks

While refreshing, sugary drinks can cause a quick blood sugar spike and subsequent crash, leading to fatigue. 

The added sugars can also increase urination, potentially causing dehydration and further sapping your energy. Moderation is key with these drinks to avoid energy lulls.


Alcohol may seem relaxing, but it can interfere with your sleep cycle and lead to dehydration. These effects can leave you feeling tired. It's essential to balance alcohol consumption with water intake to maintain hydration and energy levels.

Fast Food

Fast food, while convenient, is often high in unhealthy fats and sodium. These ingredients can lead to a quick energy crash, leaving you feeling lethargic. Opting for balanced meals with whole foods can support sustained energy levels.

Processed Foods

These foods often contain unhealthy fats, added sugars, and high amounts of sodium. The quick energy spike provided by these foods is often followed by a significant drop, leading to feelings of tiredness and sluggishness.

What Foods Can Support Energy? 

Feeling energized isn't just about avoiding energy-draining foods but filling your plate with foods that boost your vitality.

Here are some superstars that can help elevate your energy levels:

  • Bananas: Bananas are delicious and packed with potassium, an essential nutrient that plays a significant role in energy production and muscle function.
  • Brown Rice: Brown rice is a whole grain that's high in complex carbs and fiber. This combination provides a slow release of energy, helping to keep you energized throughout the day.
  • Sweet Potatoes: These vibrant vegetables are rich in fiber and loaded with energy-boosting nutrients like magnesium and vitamin A, making them an excellent choice for sustained energy.
  • Eggs: Eggs are an excellent source of high-quality protein, which can provide you with sustained energy by stabilizing your blood sugar and preventing energy crashes.
  • Apples: Apples are rich in fiber and natural sugars, making them a healthy choice for a quick, energy-boosting snack.
  • Chia Seeds: These tiny seeds are packed with omega-3 fatty acids, fiber, and protein, all of which can contribute to sustained energy levels.
  • Quinoa: Quinoa is a powerhouse grain that contains all nine essential amino acids, making it a complete protein. This can provide a steady and sustained release of energy.
  • Oranges: Oranges are a great source of quick energy due to their natural sugars, and they're also loaded with vitamin C, an antioxidant that aids in energy production.
  • Spinach: Spinach is packed with iron, a nutrient essential for energy production and oxygen transportation in the body.
  • Yogurt: Yogurt is a great source of protein and healthy fats. This combination can help maintain steady energy levels by slowing down digestion and stabilizing blood sugar levels.
  • Almonds: Almonds are nutrient-dense snacks that deliver a mix of healthy fats, fiber, and protein, all of which are essential for sustained energy.
  • Oats: Oats are a whole grain that provides slow-release energy due to their high fiber content and complex carbohydrates.
  • Beans: Beans are a great source of fiber and protein. This combination can help to stabilize blood sugar levels and provide sustained energy.
  • Green Tea: While it doesn't contain caffeine, green tea is known for its energy-boosting properties due to its rich antioxidant content.
  • Dark Chocolate: Dark chocolate is rich in antioxidants that support cellular health and energy production. It also contains a small amount of caffeine, providing a natural energy boost.

How Else Can You Support Energy Levels? 

Aside from incorporating more energy-boosting foods into your diet, there are other lifestyle changes you can make to support your energy levels, such as: 

Get Regular Exercise

Regular physical activity is key to maintaining high energy levels. Exercise increases blood flow, ensuring cells receive the oxygen and nutrients needed to produce energy. Whether it's a brisk walk, a yoga session, or a vigorous workout, find a routine that suits you and make it a part of your daily life.

Eat a Balanced Diet

Eating a balanced diet is crucial for sustained energy. Whole foods, such as fruits, vegetables, lean proteins, and whole grains, provide a wide range of nutrients that your body needs to produce energy. 

Moreover, they release energy slowly, helping to maintain stable blood sugar levels and prevent energy crashes. Remember, it's not just about eating the right foods but achieving a balance of nutrients to support overall health and energy levels.

Stay Hydrated

Hydration is often overlooked when it comes to energy levels. Water plays a critical role in numerous bodily functions, including the production of energy at a cellular level. 

Dehydration can lead to feelings of fatigue and decreased cognitive abilities. So, remember, staying adequately hydrated isn't just about quenching your thirst; it's about fueling your body's energy production process.

Get Enough Sleep

Quality sleep isn't a luxury; it's a necessity for good health and energy. During sleep, your body works to repair cells, restore energy, and release hormones that regulate growth and appetite. 

Skimping on sleep can leave you feeling drained, impair concentration, and lower energy levels. Prioritizing sleep is an investment in your overall well-being and energy levels.

Practice Stress Management

Chronic stress can be a significant energy zapper. When you're constantly in “fight or flight” mode, it can leave you feeling exhausted and drained. 

Incorporating effective stress management techniques, such as meditation, deep breathing, yoga, or even a relaxing hobby, can help reduce stress levels and boost your energy. Remember, your mental health is just as crucial as your physical health in maintaining energy levels.

Take Regular Breaks

In our fast-paced world, taking a break can sometimes feel like a luxury. However, regular breaks are essential to prevent burnout and maintain high energy levels

Whether it's a five-minute break to stretch, a short walk, or a moment to enjoy a peaceful view, these brief pauses can recharge your energy and improve productivity.

Maintain a Healthy Weight

Your weight can significantly impact your energy levels. Carrying excess weight can put a strain on your body, leading to fatigue. 

Conversely, too much weight loss can leave you underweight, which often results in feeling weak and low on energy. Finding and maintaining a healthy weight through a balanced diet and regular exercise can support optimal body function, including energy production.
