The average person's activities won't usually cause him to feel starved and drained after a few hours without food, but such an outcome is much more likely where insufficient consumption concerns exceedingly sporty folks. The FuelME is a serious-business lunchbox that's been designed especially for athletes.
You'll notice that Han Huynh's backpack cooler is quite large, and thus capable of storing a full buffet of edibles from all necessary food groups. One can store multiple meals and numerous snacks within the hi-tech-looking canister so that a full day of intense training is possible. No lengthy breaks to search for supper would be required, just adequate advanced preparation. The FuelME encourages the user to make deliberate decisions about his diet so that intake and output are balanced for optimal health.
