Astronauts in space require a higher calorie intake (2,500–3,800 daily) compared to those on Earth (2,000–2,500). Microgravity increases energy expenditure due to physiological adaptations, increased exercise to combat muscle and bone loss, and a higher basal metabolic rate. The body works harder to maintain basic functions, thermoregulate, and manage fluid shifts, all contributing to the elevated caloric needs.from LifeStyle - Latest Lifestyle News, Hot Trends, Celebrity Styles & Events https://ift.tt/qiFUb42
