We all get our calories from our foods, so it is important to understand why diet is so important. Food not only provides nutrition, but also calories. And calories provide energy. If you live a sedentary lifestyle, all those calories you take in will not disappear into the blue, but will be turned into fat. That’s how your body works – It doesn’t like to waste.
Understanding this can help you to plan your calorie intake everyday. This in turn helps you to plan your weight if you have weight problems. The calories needed per day differs from individual to individual. A male needs more calories than a female. An overweight person needs less calories than a lighter weighing person. An elderly person requires less calories than a youngster.
All these things are taken into account when you want to plan your daily calorie intake so as to be optimal. There is no exact figure, but if you want to know, 2000 calories per day for males and 1800 calories for women seems to be a very rough figure bandied about now and then.
