Identical to on Earth, the place a discount in calorie consumption impacts physique weight, the identical occurs in house. Specialists say the impact is compounded with microgravity or little or no gravity.
“Microgravity can have an effect on bone and muscle turnover. There may be fast caloric loss and protein deficiency coupled with dietary deficiency, which may result in a shift in fluid and electrolyte steadiness in extended keep in house,” mentioned Dr Rajiv Kovil, head of diabetology, Zandra Healthcare and co-founder of Rang De Neela Initiative.
He added that being in house causes astronauts to burn energy rapidly and lose some essential vitamins with extended keep. “On Earth, we don’t often take into consideration gravity serving to our muscle tissue and bones keep wholesome, but it surely’s all the time there, gently pulling us down and giving our our bodies a pure exercise. With out this fixed pull, the physique has to work more durable in house, which makes use of extra power and vitamins,” elaborated Dr Kovil.
With out robust gravity, Dr Kovil defined that astronauts’ bones and muscle tissue don’t get as a lot train as they do on Earth, in order that they begin to weaken. “To maintain them robust, astronauts must train quite a bit—round 2 to three hours on daily basis,” mentioned Dr Kovil.

Dr Kovil shared that astronauts want round 4,000 energy to fulfill their every day wants. “It’s often double what you require on Earth,” mentioned Dr Kovil.
Usually, a male astronaut requires round 2,700-3,700 energy every day, whereas feminine astronauts might have about 2,000-2,700 energy, mentioned Dr Birali Swetha, chief dietician, Gleneagles Conscious Hospital, LB Nagar, Hyderabad. “These wants range based mostly on physique dimension, mission actions, and particular person metabolism, however they often surpass Earth-based calorie necessities as a result of microgravity atmosphere, which will increase power calls for on the physique,” mentioned Dr Birali.
