When it comes to achieving dietary or weight loss objectives, the term “calorie” is commonly used. Are you familiar with the meaning of a calorie? Essentially, a calorie represents a unit of energy.
When it comes to nutrition, calories denote the energy that inpiduals obtain by consuming food and beverages, as well as the energy expended during physical activities.
If you carefully examine the nutrition label of a food item, you’ll notice that the calorie content is listed. Additionally, numerous weight loss programs focus on decreasing calorie intake.
In this informative article, we’ll delve into the topic of calories in relation to food and beverages, as well as how the body utilizes this energy. We’ll explore the recommended daily calorie intake and ways to obtain these calories to sustain optimal overall health. Stick with us for more insights.
What is a calorie?
While the majority of inpiduals connect calories with food and beverages, it’s important to note that anything that contains energy has calories. As an example, one kilogram of coal contains approximately 7,000,000 calories.
There exist two types of calories:
- A small calorie (cal) represents the energy required to increase the temperature of 1 gram of water by 1 degree Celsius.
- A large calorie (kilocalorie) signifies the energy necessary to elevate the temperature of 1 kilogram of water by 1 degree Celsius. One kilocalorie equates to 1000 calories.
It’s common for the terms “big calorie” and “small calorie” to be used interchangeably. However, on nutrition labels, calories refer to kilocalories. Therefore, a 250 calorie chocolate bar actually contains 250,000 calories.
How to calculate the daily need for calories
According to the American government, the average daily calorie requirement for men is 2,700 kcal, and for women, it’s 2,200 kcal.
It’s essential to note that not everyone necessitates the same quantity of calories daily. Each inpidual has a unique metabolism that burns energy at various rates, and physical activity levels can also differ.
Numerous factors influence the recommended daily calorie intake, including:
- Overall health status
- Level of physical activity
- Gender
- Weight
- Height
- Body composition.
Empty Calories
Empty calories are foods that supply energy but contain very little nutritional value. These food items provide “calories without nutrition” as they do not have any dietary fiber, amino acids, antioxidants, dietary minerals, or vitamins.
According to the official dietary guidelines of SelectMyPlate.gov, empty calories are derived mostly from solid fats and added sugars.
Solid fats refer to the type of fats that are naturally present in many foods, but are also commonly added during industrial food processing or preparation of certain foods. An example of solid fat is butter.
Added sugars, on the other hand, are sweeteners that are added to foods and beverages during industrial processing. These are calorie-dense and common types of added sugars in the US include sucrose and high fructose corn syrup.
While solid fats and added sugars may enhance the taste of our food, it’s important to remember that these types of food are high in calories and are among the main culprits of obesity.
Alcohol is another significant source of empty calories. Just a normal serving of beer can add 153 kcal to a person’s daily intake.
Sources of empty calories
Here are the foods and drinks that are known to provide the most empty calories:
| Solid fats and added sugars | Solid fats | Added sugars |
|---|---|---|
|
Ice cream Doughnut Sweets Biscuit Cake |
Rib meat Bacon Sausage Cheese Pizza |
Fruit drinks Sports drinks Energy drinks Soda (soda) |
Sugary beverages represent a significant contributor of empty calories in the American diet. Over fifty percent of Americans consume at least one sugary drink daily.
There are various methods to reduce the amount of solid fat or added sugars in products. For instance, one can opt for low-fat alternatives to high-fat foods like hot dogs or cheese. However, it’s worth noting that even lower-fat options cannot replace the calories obtained from nutritious sources.
According to Rachel Johnson, spokesperson for the American Heart Association (AHA), sweetened drinks represent a primary source of calories in the American diet, and contribute to fifty percent of the total added sugars consumed by people.
The majority of Americans have a diet that lacks essential nutrients. Recent research has shown that consuming over one sugary beverage daily heightens the probability of developing high blood pressure.
It’s advisable to steer clear of sugary drinks altogether and opt for healthier alternatives such as water, fat-free or 1% fat milk, natural fruit juice, and low-sodium vegetable juice.
Incorporating fresh and nutritious food and beverages into your diet is an effective way to reduce your consumption of empty calories or even eliminate them entirely.
