Tag: Daily energy requirements

The average adult needs about 8,700 kilojoules (kJ) per day to maintain a healthy weight, but this is a broad average and individual requirements vary significantly. Your specific daily kilojoule target is not a one-size-fits-all number but a dynamic figure influenced by multiple personal factors.

According to the Dietary Guidelines for Americans, a sedentary 18-year-old female typically needs 1,800 calories per day, while an active male of the same age can require up to 3,200 calories. These figures highlight that there is no one-size-fits-all answer to daily energy needs at this age.

According to the NHS, an average woman needs around 2,000kcal a day, but this is a rough guideline and not a fixed rule for everyone. What is the daily energy intake for a woman depends heavily on individual factors, meaning a one-size-fits-all approach is not effective for personalized health and fitness goals.
