Carbohydrates are an essential part of a healthy diet because your body converts them to glucose and your body runs on glucose. Proteins, fats, and alcohol (as in beer, wine, and spirits) also provide energy in the form of calories.
There are three main types of carbohydrates, which are sugars, starches and fibre. Carbohydrates contain about 4 calories per gram. The main function of carbohydrates is to provide your body with fuel and energy that is required to carry out daily activities and exercise. When carbohydrates are in our body, they are being broken down and used as energy. When the body doesn't need to use the carbohydrates for energy, it stores them into the liver and muscles and is called glycogen. When the liver and muscles cells cannot store anymore glycogen, it is turned into fat.
