The minimum amount of calories a person can survive on varies based on several factors, including age, sex, body composition, and overall health. Generally, most health experts suggest that an adult needs at least 1,200 to 1,500 calories per day to maintain basic bodily functions, especially when sedentary. However, this number can be lower for short periods under strict medical supervision.
Survival situations can be different, where individuals might sustain themselves on significantly fewer calories for brief periods. However, consistently consuming fewer calories can lead to serious health issues, including malnutrition and organ failure. It’s always best to aim for a balanced diet that meets your individual nutritional needs. If you or someone you know is considering calorie restriction or fasting, it’s essential to consult with a healthcare professional.
