Calories are anything that contains energy!

Calories

Calories are associated with drink and food by most people, but anything that contains energy has calories. According to scientists, calories mean a unit of energy or heat that could come from various sources. In a nutritional sense, fats, proteins, carbs, sugar are all important sources of calories needed for body functions. Brains, muscles and every cell in the body need the energy to function in its optimal state. If a person doesn’t get enough nutrients, there are negative consequences like not having the power, concentrating, or losing lean mass.

According to the government in the U.S., the average woman needs 2200 calories per day, and the average man needs 2700 calories per day. Each day not everybody needs the same number of calories. Energy is burnt at different rates because people have different metabolism, and some have more active lifestyles than others. The recommended intake of calories per day depends on overall general health, physical activity demands, sex, weight, height, body shape. For adults, 45 to 65 percent of calories should come from carbs, 20 to 25 percent should come from fat, and 10 to 35 percent should come from protein. Children need more calories. Only 25% of calories should come from added sugar.

The human body needs calories to survive. Without energy, cells in the body would die, the heart and lungs would stop, and the organ would not function. From food and drink, people get this energy. According to health experts, if people consume only the amount of calories required per day, they will live a healthy life. Health problems can be caused by low or high consumption of calories. The energy in the food can be found out by the number of calories it contains. Not only are calories necessary, but the source from which the calories are taken is also important. 1g of carbs contains four significant calories, 1g of protein includes four large calories, and 1g of fats contains nine significant calories.

According to a report published in CDC in 2013, 11.3% of calories consumed comes from fast food in the U.S. Healthcare professional says this to high. Older people get fewer calories from fast food. The time at which people eats influences how effectively the body uses calories.

Weight loss and calories –

It is essential to consume sufficient calories, but reducing calories can help to reduced weight. Through physical activities, calories are expanded. Calories and body weight have a relation between them. The CDC refers to the balance of calories burned and calories consumed as caloric balance. If a person is balanced, then the calories consumed are balanced by the calories burnt. This means bodyweight will be maintained. 

If a person maintains body weight, they are into caloric balance which they are eating almost the same amount of calories that they are burning. If a person has excess calories, more calories are consumed than burnt, which will cause weight gain. When people try to lose weight, they tend to have a caloric deficit. Sufficient calories need to be consumed by a person with a caloric deficit to function and stay healthy. During the weight loss process, adequate calories help to maintain muscle mass and make weight loss sustainable. Consuming sufficient calories during the weight-loss process is also essential to maintaining a healthy metabolic rate.
