End of summary

The energy we absorb daily through food and drinks serves as fuel for us, both in everyday life and for our metabolism. For those aiming to change their weight and struggling to feel satiated through eating, it is crucial to pay attention to the calorie density or energy density of the consumed foods.

What is meant by energy density?

Energy density or calorie density refers to the number of calories in relation to the volume of a food item or the calories per unit weight of the food. For example, an apple has a lower calorie density with 50 kilocalories per 100 grams compared to a banana with approximately 90 calories per 100 grams. Generally, foods with high water content and large volume have lower energy density.

Anyone planning a change in diet or weight should already be familiar with energy density. For instance, someone looking to lose weight by avoiding junk food should be aware of the significant differences between various foods.

Since it's not the calories that satisfy us but the quantity of consumed food, it makes sense, during weight reduction, to incorporate foods with low calorie density into the diet plan. This allows for eating more, which is satisfying, without feeling guilty.

On the other hand, for those aiming to gain weight, a diet plan with particularly high calorie density is the easiest. However, it is essential to cook fresh and healthy meals to counteract potential deficiencies instead of relying solely on fast food.

Energy density of food

It is repeatedly surprising to discover that supposedly healthy or weight-loss-friendly foods can have a relatively high calorie density. However, this does not necessarily mean that foods with high calorie density are unhealthy or should be avoided.

Depending on the life situation and goals, some foods can be genuine aids, both in weight gain and, in moderation, in weight loss. For example, avocados, due to their high fat content, contain many calories with low weight. Oats are also healthy despite having a high carbohydrate and energy density.

However, it is not necessary, and it would be a significant sacrifice, to completely avoid these foods during weight reduction, as they contain many healthy ingredients.

To still get an overview of energy density, the following tables provide guidance.

Foods with low energy density

A low energy density is considered when it is below 1.5, approximately 150 kcal per 100 grams. While this may sound like a lot initially, it becomes clear that these numbers are likely rare in a regular refrigerator, especially in processed products.

Fruits

Vegetables

legumes

meat products

Dairy products

Average Energy Density

Products with an average energy density range from approximately 151 to 240 kcal/100 grams, corresponding to an energy density of 1.5-2.4. However, these values are seldom found in ready-made products. For those aiming to lose weight, it is advisable to be cautious about consuming an excessive amount of food from this category.

Food with Increased Energy Density

Starting from 241 kcal/100 grams, or a value exceeding 2.4, food is classified as having an elevated energy density. These prove particularly beneficial when aiming for weight gain and should be available in a healthy form in the pantry. Nevertheless, there are also food items suitable for those looking to lose weight due to their healthy nutrients – such as seeds.

When should you eat which foods?

Many individuals pay particular attention to calories when adjusting their own body weight. A sensible and promising measure to lose or gain a few kilos involves eating in a calorie deficit or surplus.

To make the process of losing or gaining weight even more straightforward and to avoid binge eating, it is advisable to consider the energy density of calories.

Foods for Weight Loss

To successfully lose weight, as mentioned earlier, a calorie deficit should be maintained. However, during weight loss, one often feels as hungry as during dieting. In this case, the focus should primarily be on foods that not only have a high volume but also a significant water content.

The following foods have a low energy density for weight loss:

• Any fruit
• Any vegetables
• Beans
• Peas
• Lean poultry (turkey breast, chicken breast)
• Low-fat dairy products (skimmed quark, skimmed milk)

Foods for Weight Gain

To gain weight at a healthy pace and keep all metabolic processes running, foods with a higher energy density should be included in your meals. Healthy compositions and balanced meals are crucial here and are significantly healthier than burgers or pizza.

These foods have a particularly high energy density and, at the same time, contain many healthy fats, carbohydrates, proteins, and minerals:

• Sweet fruits (dates, raisins)
• Carbohydrate sources (whole grain pasta, potatoes, rice)
• Legumes
• Nuts
• Pork meat
• Full-fat dairy products

Calculate calorie density

The calculation of the energy density of food is not a difficult task. All you need to know is the kilocalories per 100 grams. Now, divide the number of calories by 100 to obtain the energy density. You can then compare it with the tables above to determine whether a food has a high, normal, or low caloric density.

Example calculation for red lentils:

335 kcal / 100g

335/100 = 3.35

Red lentils have a high caloric density of 3.35

Conclusion

Even though a caloric deficit or surplus ultimately leads to success in weight loss or gain, there are several ways to keep hunger in check. In addition to drinking plenty of water, foods with high volume and a significant water content are also beneficial for getting in shape. Vegetables, in particular, meet these criteria. However, a balanced diet should not neglect sufficient healthy fats, such as those from avocados and nuts, and complex carbohydrates. In general, the principle of low caloric density is highly effective for weight loss through consuming large quantities, but one should not restrict themselves too much and consume foods with medium or high caloric density in moderation.

Frequently asked questions about energy density

Why is energy density crucial for losing and gaining weight?

Above all, the quantity of consumed calories is crucial when it comes to losing or gaining weight. However, to endure in the long term and not restrict oneself, the amount of consumed food plays a decisive role. Foods with a low energy density (less than 1.5) can be consumed in larger quantities without exceeding the calorie deficit.

How is calorie density calculated?

Calories / 100 grams / 100 = Energy density

When do we consider high calorie density?

High calorie density is considered from 2.4. This means that foods with 240 kcal/100 grams or more have a high energy density and should be consumed in moderation by those aiming to lose weight.
