the problem is they actually don't give you energy.. now let me explain before 20 guys flame me for saying that
things that are hard to digest actually reduce energy because the body needs to work more to digest them. our bodies expels 50% of our energy a day trying to digest food.
beans, nuts, seeds are all very hard to digest unfortunately. i would swap into papaya and watermelon instead. if you don't have access to tropical fruits look into peaches and apples for energy
