How many calories does the average person eat per day worldwide?

How to get close to this number

Start from the number everyone knows — the two-thousand-calorie guideline on food labels — and then adjust for the fact that this figure measures supply rather than consumption. Supply must exceed consumption because food is wasted at every stage, so the answer has to sit meaningfully above the dietary reference. That adjustment is the whole question.

The distinction in the explanation is the one to internalise: this is food available per person, not food eaten. It counts what enters the food system and divides by population, so household waste, retail spoilage and food fed to pets all sit inside it. Quoting it as "what people eat" is the most common misuse of this statistic, and it inflates apparent intake considerably.

The trend is more informative than the level. As the explanation says, the figure has risen by a third or more since the 1960s, which reflects genuine improvement in food security across much of the world alongside rising waste and rising obesity. A global average also conceals enormous variation between countries, so this number describes an aggregate that nobody actually lives.
