Most nuts like almonds, peanut butter, and cashews are loaded with nutrients, healthy fats, and are an excellent source of protein. It is very common for many of us feel tired and beat halfway through the workday. This can be attributed to a lack of nutrients and energy in our diet. Because we know that not all calories are created equal, it’s important to choose foods that give you energy.

Foods for Energy
The energy in our body is a direct correlation of the energy in the food we eat.

If our body is an engine, food is the fuel our body needs to perform properly. It is important that we fuel our bodies with nutrient dense foods, and never let our tanks go on empty.

What is Energy Density?

Understanding energy density can be useful if you’re trying to minimize or maximize your calorie intake. Energy density is the amount of energy or calories per gram of food.

Studies have shown that people tend to consume about the same amount of food each day in terms of weight, but not necessarily the same amount of energy (calories). Foods with a lower energy density provide fewer calories per gram than foods with a higher energy density.

For the same amount of calories, a person can consume a larger portion of food lower in energy density than a food higher in energy density. This is because the composition of foods influences energy density values. Water, for instance, lowers the energy density of foods because it has an energy density of 0 kcal/g and contributes weight but not energy to foods.

On the other end of the spectrum, we have fat. Fat is the most energy-dense component of food, providing more than twice as many calories per gram compared to carbohydrates and protein.

What are Energy-Dense Foods?

Foods are divided into three categories of energy density. There are low-density foods, which include foods with lots of water and fiber, but are low in fat. Foods with low energy density are typically very filling. These foods include fruits and vegetables, low-fat soups, yogurt, and legumes.

Many studies have confirmed that consuming a lower energy-dense diet can be an effective way to control hunger and reduce your calorie intake. To maintain a healthy weight, a diet consisting of low energy-dense foods is recommended.

Energy-Dense Foods

The medium energy density category has a wide range of foods. It is important to incorporate some of these food items into a well-balanced diet plan. Foods in this category include salmon, low-fat cheese, and lean red meats. Pizza, fried chips, and pastries are also considered medium energy-dense foods that should only be consumed every so often.

Foods in the high energy density category tend to be high in fat and have low water content. High energy-dense foods include bread, butter, cheese, oil, and condiments such as mayonnaise. When consuming a low energy density diet, you can still eat foods from this category, but in small portions and not too often.

Energy Density Has Nothing to Do with Nutritional Value

“Energy density” and “nutrient density” are phrases that are mistakenly seen as interchangeable but in actuality describe completely different aspects of food. Energy density has nothing to do with the actual nutritional value of any one food item.

Nutrient density refers to how much nutrition a food provides per calorie. It is most useful as a way to compare two food items. If a food item provides more nutrition for the same amount of calories or fewer calories, then it is more nutrient dense than the other food item.

Keep in mind that energy density doesn’t take the nutritional value into account at all. Because nutrient density takes both nutrition and energy (or calories) into account, it’s probably a better guide for overall nutrition.

The great thing about foods with low energy density is that they often are also nutrient dense providing a lot of nutrients per serving size. Many types of fruits, berries, and vegetables are low in calories, high in fiber, and contain lots of vitamins and minerals.

How Does Food Give You Energy and Stamina?

The energy in our body is a direct correlation of the energy in the food we eat. The food we eat provides units of energy in the form of calories that give our bodies fuel to perform all necessary functions from breathing to walking to any challenging form of physical activity. These macronutrients are broken down and digested to provide our body with fuel to get through the day.

The acids and enzymes in our stomach break down our food for digestion. Carbohydrates are broken down into glucose and absorbed into the bloodstream. Fat is a major source of stored energy and is held in our body until we need it, and fat is actually the preferred source of energy for the heart. Protein is a long-lasting form of energy that is broken down slowly. It is primarily used as energy when the body has a low number of carbohydrates to obtain energy from, and total calorie intake is too low.

Energy and Stamina
Complex carbohydrates, such as whole grains, provide a more steady release of energy throughout the day.

Energy and Physical Activity

During physical activity, the body uses calories from all three sources of macronutrients. High-intensity activities require energy derived from primarily from carbohydrates. During moderate, more extended physical activity, the body burns mostly fat with a slight use of carbohydrate and protein energy.

Every piece of food we eat supplies calories for energy, but not all calories are created equal. Certain foods provide more vitamins and minerals for the amount of energy they supply, which is why choosing nutrient-dense foods to fuel the body with the daily energy it needs is so important.

Every piece of food we eat supplies calories for energy, but not all calories are created equal.

Foods high in sugar and low in nutrients are broken down quickly and don’t supply sufficient energy. Complex carbohydrates, such as whole grains, provide a more steady release of energy throughout the day. Lean proteins are also a good source of energy for our body. Chicken breast, beans, and healthy fats are all examples of lean protein.

13 Foods That Give You Energy

Generally speaking, all of the food we consume is suppose to give us some form of energy. But, some foods are better at providing the sustained energy we want to help us remain productive for the entire day.

Try munching on some of these energy boosting foods to keep you alert throughout your busy day:

1. Eggs

Eggs
Eggs

Eggs are high on our list of foods that give you energy. They tend to score high on the satiety index and provide plenty of power to fuel your day. A single egg has just 70 calories and is packed with 6 grams of protein.  They contain heart-healthy monounsaturated and polyunsaturated fatty acids to help you stay energized and prevent overeating.

Most of the nutrients are found in the yolk of the egg, which is filled with antioxidants and all 9 essential amino acids.  The protein in eggs gives you a steady and sustained source of energy because it doesn’t spike blood sugar or insulin levels in the body when digested.

Leucine, one of the most abundant amino acid in eggs, can help cells take in more blood sugar, stimulate the production of energy in the cells and increase the breakdown of fat to produce energy.  The vitamin B in eggs also helps enzymes in the body perform their role in the processes of breaking down food for energy.

2. Apples
