A Calorie Tracker is a tool or application designed to help individuals monitor their daily calorie intake and expenditure. Users can log the foods they eat, along with their portion sizes, to calculate the total calories consumed. Many trackers also allow users to input physical activities to estimate calories burned, providing a clearer picture of their overall energy balance. These trackers often come with additional features, such as meal planning, nutritional information, and progress tracking. By using a Calorie Tracker, individuals can set dietary goals, manage their weight, and make healthier food choices based on their personal needs and preferences.
