Search for the calorie count of different foods by using an online nutrition database such as CalorieKing.com or CalorieCount.com. Most store-bought foods list the calorie count per serving in the nutritional information panel on the packaging.
To use the calorie content database on Calorie Count, enter a food in the search bar at the top of the page. If the food exists in the database, the website directs the user to a page listing possible variations on the food. Click the option that most closely matches the desired food item. Each food is shown with comprehensive nutritional information including the calorie count and the overall nutritional grade.
