Why should the Estimated Energy Requirement $($EER$)$ be used with caution?

The EER represents average energy needs, so it meets or exceeds the needs of half of the individuals in a group.

The EER is set at the low end of a group's energy needs because there is a high rate of obesity in the United States.

The EER does not take into account physical activity levels, so it may underestimate the energy needs of active individuals.

The EER is set to meet the needs of $98\%$ of individuals in a group, so it overestimates most individual's energy needs
