Human: How do I find out how many calories I need every day? Assistant: 
To find out how many calories you need each day, you can calculate your Basal Metabolic Rate (BMR). This is the number of calories your body needs to function at rest and it varies from person to person. You can use online calculators or apps to help you determine your BMR. Once you know your BMR, subtract the number of calories you burn through physical activity and any additional calories you may need for other activities such as eating, drinking and breathing. The result is the total daily calorie requirement.
