When it comes to weight loss and weight management, we all want things to happen quickly and easily. However, the truth is that this is impossible and we should look for a moderate approach. In this regard, it is very useful to track the intake of calories that enter the body from various foods and drinks.

Why are calories so important?

As a general scientific term, a calorie is defined as the amount of heat needed to raise the temperature of a unit of water from zero degrees Celsius to 1 degree. In dietetics, the calorie is a unit of energy that comes from the foods we eat. 

Calories matter in your diet because they determine whether you gain, lose weight, or maintain your weight. In addition, both the total number of calories you take in and the source of those calories can affect your health. 

The caloric balance of your diet is one of the factors in determining overall health. You are in caloric balance when, over time, the number of calories you take in corresponds to the number of calories you burn through metabolism and physical activity. With excess calories, you consume more calories than you use, and this can lead to weight gain. In contrast, a calorie deficit means that you burn more calories than you consume, leading to a loss of body mass. 

During growth, a calorie surplus is needed, but involuntary intake of more than the required amount of calories leads to unwanted weight gain. Purposefully putting yourself into a calorie deficit can help you lose unwanted weight, which can help with conditions such as obesity, type 2 diabetes, inflammatory diseases, depression and anxiety, even cancer.

The proportion of calories you take in through the various macronutrients proteins, carbohydrates and fats is just as important as the absolute number of calories you take. A healthy, well-balanced diet that supports all of your body's physiological processes implies 10 to 35 percent calories from protein, 45 to 65 percent from carbohydrates, and the remaining 20 to 35 percent from fat. 

Consuming just the number of calories you need to maintain your body's functions also helps you stay healthy. Taking more than necessary can eventually lead to obesity, with an increased risk of cancer and metabolic disorders.  2

And now, let's move on to today's important question, namely:

What are some foods with zero (0) calories?

Contrary to what the name suggests, these foods don't have zero calories. So how can foods be zero-calorie if they have some nutritional energy in them? According to health experts, these foods, also known as near-zero-calorie foods, are vegetables and fruits that supposedly take up more energy to digest than they provide for your body. Thus, their effect in the body leads to the expenditure of more calories than provided, which to some extent makes them foods with 0 calories.

There are a number of benefits to eating near zero-calorie foods. First, they can help you feel full longer. This means you'll be less likely to overeat and snack between meals. Most of these foods contain fiber, healthy fats, and protein that help you feel full from food. Some have a high water content, which can also help with satiety.
