It's my anecdotal experience that the trend of people 'feeling tired all the time' in modern American society is a result of the extremely large caloric intake that's become common for most meals.
I'm actually surprised tech companies that provide free food don't actively try to limit carby/sugary offerings. Even things like cereal+milk are just glorified candy bars (nutritionally speaking).
I think it comes down to a combination of money and perishability. Healthy food is expensive and perishable. Carby snacks are cheap and have a long shelf life.
