The first step is knowing exactly what you're eating. This sounds simple, but restaurant meals and home-cooked dishes can be tricky to break down.
A "cup" of rice at home vs a restaurant can vary by 2-3x calories. Accurate portion estimation is where most people struggle.
Search through databases, compare entries, and hope you find the right match. This step alone can take minutes per food item.
Finally, enter each item into your tracker. For a meal with 5 components, this can take 5-10 minutes of tedious work.
