Note: The daily calories provided by food should not be less than 5,000-7,500 kilojoules, which is the least energy to maintain normal life activities. Generally speaking, adults need at least 1500 kcal of energy every day to maintain body function, because even if you lie still, your body still needs energy to maintain body temperature, cardiopulmonary function and brain operation. Basal metabolic consumption varies with individual height, weight, age and gender.
