Who could use a little more energy?

One of the biggest complaints of the women that I work with is that they just don’t have enough energy. They struggle to get out of bed and moving in the morning and by the time they are done work and getting home to make themselves dinner they are wiped out. This leads a lot of them to reach for easy to prepare processed meals or going out for fast food. There must be an answer! Why are all these women SO tired?
