What is the recommended amount of daily calories?

It depends on your age, gender, size and activity level, among other things. For a small, elderly female living a mostly inactive lifestyle, just 1500 calories could be enough. An extremely active teenage boy could need 3000+ calories a day to maintain his weight. Nutrition labels tend to assume a 2000 calorie diet, but your exact needs could be more or less.

At a young age you shouldn't be too aware of how many calories you need to take in, just eat well and take regular sessions of exercise.

It also depends on whether you want to lose weight, gain weight, or maintain weight. For more information and examples regarding calories for adults, or information and examples regarding calories for teenagers, please see the page links, further down this page, listed under Related Questions.
