As someone who regularly does 24-36 hour fasts (alternate day fasting), it's not as difficult as you'd think. For me at least some of the weird/unexpected side-effects (insomnia being my major one) are harder to deal with than the hunger pains. I generally will have less energy at the gym on fast days but even that can vary and you have more than you'd expect.

One thing I've come to learn from doing this for years is our bodies really accept fasting well...which makes sense from an evolutionary perspective. We really are "built" to fast.
