Question

Why do you think that the calorie intake of people is so low

Answer 1

because the time has changed, the people don't work physically but work mentally

Answer 2

Many of the world’s poor consume very few calories. Because calories are not just consumption, but also an input into production, this low consumption has the potential to dampen labor productivity and impede decision-making. Low caloric intake may therefore play a key role in the productive capacity of the world’s poorest and the firms which hire them. Economic theory in this area is extensive. However, given the inherent challenges posed by the endogeneity of caloric intake and the measurement of productivity, empirical work is less well-developed. The main goal of our research is therefore to generate rigorous causal evidence regarding the impact of low caloric intake on productivity, cognition, and decision-making.
