How many calories do you need to eat to maintain 800 pounds?
That depends on how many calories the person in question's body requires to stay alive, or their BMR (basal metabolic rate) which depends on age, sex and weight. If they need 3000 calories, they will need to eat 3000 calories to maintain their weight. If they need 4000 calories, they need 4000 calories to maintain their weight. In addition, if they eat more than their BMR, they will gain weight, if they eat less, they will lose weight. In theory, you can have 2 totally different people who weight 800 pounds, BUT they each require different amounts of calories to maintain their 800 pounds.
