It's likely that you have heard of calories before. They're a measurement of energy and the word is most often associated with food. But what exactly is a calorie? A calorie is defined as the amount of heat energy needed to raise one gram of water by one degree in temperature.
You may know that a calorie is a measure of energy and nutrition in food and drinks, but did you know how many calories your body uses every day? The average person needs 2,000 to 3,000 calories per day to maintain their weight. Some people require more or less depending on their age or lifestyle.
Eating too many calories can lead to obesity, decreased energy levels, and poor overall health. A diet lacking in fruit and vegetables can leave a person with nutritional deficiencies which can cause long-term health problems. One way to avoid this problem is by taking a daily multivitamin or by adding a variety of fruits and vegetables to your diet.
It is estimated that approximately 1.25 billion people around the world are overweight and obesity is the fifth leading cause of chronic disease and disability. With such a high percentage of people affected by too much weight, it is important to know how many calories you should be eating in order to maintain a healthy weight.
