This calculation show you approximately how many kilojoules you need each day to maintain your weight or get closer to your weight goal over a healthy period.
Everyone is different, and this is just a starting point. A good way to tell whether you are consuming the right amount of kilojoules is whether you are gaining or losing weight.
To achieve and maintain a healthy weight, it helps to check your weight regularly - try monthly, then adjust your food choices and physical activity levels depending on the results.
The good news is that small changes can make a big difference. You can find more information on healthy eating and physical activity on our website. For personalised advice, consult an accredited practising dietitian or health professional.
