This has been a godsend. Whatever I eat during the day, I sanp a picture of it. If nutritional information is available, snap that too. At the end of the day you will know exactly what you ate and when and it is a simple matter to record it in your nutrition log. (Pictured below, new girlfriend's tasty Mango Chutney Chicken and nutritional information- sort of a cheat meal but what the hell).
