(note the alt text), a busy life, and some internet-research on homemade energy-bars, these bars are intended to keep you going until you finally get to sit down to eat. Simple and easy for the “people who get hungry and don’t care about food, but also don’t want to die”*
*Sadly, like all energy bars, not actually suitable to keep you alive as a sole nutritional source. Maybe add an apple.
