In Australia, Energy is not a nutrient but it is something which is released from food to fuel our body. The energy we get from food to fuel our body, is measured in kilojoules. Fat, carbohydrate and protein all provide energy and are found in foods which also supply vitamins and minerals. Alcohol also provides energy but this is not essential to the body and generally does not provide any vitamins or minerals. Energy requirements vary with age, gender, body size and activity levels. The Energy Requirements Calculator estimates your daily energy requirements for good health based on what your body needs for breathing, circulating blood, digesting food and physical activity. This may change from day to day. Any energy intake above the estimated requirement is likely to result in weight gain. If you are aiming to maintain your current weight, use your current (actual) body weight in the calculator below. If you are aiming to lose weight, use your ideal body weight in the calculator below. This will give you a lower estimated energy requirement and may help you to start losing weight.
