If a food isn’t in your tracking app’s database, you can add it manually. Most apps allow you to create custom entries by inputting the food’s name, calories, serving size, and macronutrient breakdown. For packaged foods, use the nutrition label. And for fresh or homemade items, you can estimate based on similar foods or use online nutritional databases for guidance. Some apps also let you scan barcodes or import recipes. While it may take extra effort initially, creating custom entries ensures accurate tracking and expands your app’s database for future use.
