Calorie needs vary for each person, depending on things like age, gender, health status, and activity level. To estimate your individual needs, consider using a calorie calculator, such as MyFitnessPal, The Mayo Clinic's Calorie Calculator, MyPlate Calorie Counter, or USDA's Choose My Plate resources.
Keep in mind these are just estimates, and these calculators do not account for all factors that influence calorie needs (such as changes in metabolism). Therefore, check with your healthcare provider and/or Registered Dietitian for a customized estimate that can be revised to address any changes (e.g., weight gain, weight loss, increased activity).
