One pound in weight equals 3,500 kcal. So, if you want to lose 1 pound a week in weight, you need to consume 500 kcal per day less than you normally do.
There are a number of things that can influence the amount of calories you burn:
your age – for example, growing children and teenagers may need more energy
your lifestyle – for example, how active you are
your size – your height and weight can affect how quickly you use energy
some hormones (chemicals produced by the body) – such as thyroid hormones
some medications – such as glucocorticoids, a type of steroid used to treat inflammation
To lose weight in a healthy way, you need to use more energy than you consume by eating a healthy, balanced diet with fewer calories while increasing your physical activity.
