An adult heavy worker typically requires an additional 6,000 to 8,000 kilojoules (about 1,400 to 1,900 calories) of energy per day compared to a sedentary adult. This increased energy intake is necessary to support the higher physical demands of their job, which may include strenuous activities and prolonged periods of exertion. The exact requirement can vary based on factors such as age, sex, body composition, and the specific nature of the work.

It's important to tailor caloric intake to individual needs for optimal health and performance.


Why adult woman needs less energy each day than an adult man?

Adult women generally require less energy than adult men due to differences in body composition and metabolic rates. Men typically have a higher percentage of muscle mass, which burns more calories at rest compared to fat mass, which is more prevalent in women. Additionally, hormonal differences, such as higher testosterone levels in men, contribute to greater muscle development and energy expenditure. Therefore, these physiological factors lead to lower daily caloric needs for women.
