If you have hit a wall in your weight loss plan, one of the reasons could be because you are eating too many high-calorie density foods. Let’s find out what calorie density is and how you can apply this in your daily diet to improve your health and lose weight.
What is Calorie Density?
Calorie density, also known as energy density, is the number of calories in food as compared to its weight or volume. Foods, like green vegetables, melons, and berries, that are high in fiber and water are usually low-calorie-density foods. For weight loss and management, it is important to know about calorie density. A study published in the American Journal of Clinical Nutrition found that eating bigger portions of low-calorie density foods can help to increase satiety as well as manage and lose weight.
According to research by the Centers for Disease Control and Prevention (CDC) in the US, water and fiber lower the calorie density of foods. This is because water has an energy density of 0 kcal/g and fiber has a range of energy density that lies between 1.5-2.5 kcal/g. On the other hand, and proteins have 4 kcal/g. Fat is the most calorie-dense food component with 9 kcal/g.
High-Calorie Density Foods
Let’s take a look at most commonly consumed foods with a high-calorie density.
- Fast food: A study published in the Obesity Reviews showed that the calorie density of fast foods is more than twice that of traditional, recommended healthy diets.
- Oils: Cooking oils are naturally energy-dense. However, oils like coconut oil and olive oil have several health properties that are needed by the body. Oils should not be avoided; instead, they should be had in moderation.
- Nuts: Peanuts are energy-dense with 100 grams packing 567 calories, according to the USDA National Nutrient Database. While nuts are loaded with healthy fats, they should be incorporated in limited portions in the diet. According to a report by the Harvard T.H. Chan School of Public Health, a handful of walnuts could cause a weight gain of 10 pounds or more a year, if the overall diet is not healthy and there is lack of physical exercise.
- Starchy vegetables: corn and sweet potato are more energy-dense as compared to broccoli and green pepper. For instance, half a cup of boiled corn has 72 calories and 15.6 grams of carbohydrates while half a cup of boiled contains only 27 calories and 5.6 grams of carbohydrates. like
- Cheese: Certain kinds of cheese like gruyere, parmesan, and manchego have a calorie count of more than 100 calories per ounce.
Low-Calorie Density Foods
Here is the list of foods with a low-calorie density that is recommended as staples in the pantry for a healthy diet.
- Green vegetables: Spinach and kale have a low-calorie count as compared to their volume. Vegetables like peppers, cucumbers, zucchini, and lettuce are also low in energy density due to their high water content.
- Fruits with high water content: Melons like watermelon, muskmelon, and cantaloupe are good options for fruits with low energy density. You can also have a bigger amount of berries and oranges as they have fewer calories.
- Unsweetened or lightly sweetened tea or coffee: According to Elsevier’s Physiology & Behaviour journal, lightly sweetened tea and coffee, as well as diet soda, are low-calorie density beverages. On the other hand, sweetened tea, coffee, like full-fat milk and smoothies, as well as nut milk like coconut milk are high-calorie density.
- White meat: Chicken and fish are of moderate calorie density and when baked, broiled, or grilled with minimal fat, they make a nutritious lean protein choice. They are healthier choices when compared to fatty meats like lamb, sausages, certain cuts of pork, and processed meats like salami.
Weight Loss Using Calorie Density
