Why These Values?

These are the numbers people most often look up: common per-serve figures from food labels (such as 400, 600 and 800 kJ), typical meal sizes (1,500-3,000 kJ), daily targets (6,000-10,000 kJ) and the 8,700 kJ reference used on Australian and New Zealand labels. On the Calorie side they match the round targets used by diet plans and fitness apps.
