Q: Can someone tell me why men and women eat differently?

A: Though we are the same species, our differences in gender play a huge role in how our bodies use energy. Males tend to be larger and do more physical labor, so they tend to need more energy. Females tend to be smaller, and since they carry children their diets need to be more nutritious. Because of these biological roles, our eating habits tend to vary greatly.

However, the term “tend” is an important one because not ever male is large, not every male does labor, not every female is small, and not every female gives birth. So, really, there are as many reasons why our diets are different as there are people on the planet. But understanding the biological role of consumption is a good place to start.
