Human: I'm trying to figure out how many calories I need to eat per day to lose weight. Assistant: 
The amount of calories you need to eat each day depends on your current weight and the rate at which you want to lose weight. You can calculate it by multiplying your current body mass index (BMI) with the number of pounds you want to lose in a week, then dividing that number by 7. For example, if your BMI is 25 and you want to lose 10 pounds, multiply.25 x 10 = 2.5 pounds/week /7= 0.35 pounds/day.
