Do you need to cut calories for weight loss? What’s the best way to lose weight? What are calories, why do we need them, and can a better understanding of calories help us maintain a healthier weight throughout our lives? Calories are units of energy that a food or drink provides. You can usually find calorie counts listed on food items, and wearables like the best fitness trackers allow you monitor how many calories you’re burning by doing different activities. Certain foods, such as fatty, fried, or processed foods, tend to have more calories.

We need calories to give us enough energy to move around, stay warm, grow, work, think, and play. Even our blood circulation and digestion need the energy gained from calories in order to function well. How many calories we need each day depends on our age, whether we’re trying to lose weight, how active we are, and several other factors. In this article, we’ll be taking a look at the latest research and speaking to expert nutritionists to gain a greater understanding of calories, and why they’re so important.

The term calorie has been in use since the early 19th century, when it was used to define the amount of heat required to raise the temperature of a kilogram of water from 0 degrees to 1 degree Celsius. In fact, a standard calorie is made up of 1,000 small calories, or gram calories. However, use of the term kilocalorie faded in the early 20th century, when calories became scientifically defined in terms of joules. This is why in some parts of the world, such as parts of Europe or Australia, people use the term kilojoules instead of calories. One calorie is equal to 4. Other macronutrients, such as fiber, may differ in calorie content depending on whether it is soluble or insoluble fiber.

1,600 to 2,000 calories a day, and men should take in around 2,000 to 3,000 calories a day. The less active you are, the fewer calories you’ll need. But, as the guidelines point out, the total number of calories a person needs every day can vary. It may depend on age, weight, sex, how much physical activity you do, and whether you’re pregnant or breastfeeding. These percentages are for the average person, and ratios may change for infants and young children, who need more fats in their diet.
