Out of morbid curiosity it is 453,592.5 calories for the 40 pound bag of dehydrated cereal marshmallows. The people that reviewed this seem to have gone past the death fat status into a morbidly obese zombie status. "I had done it, i finished the entire 40 pound case of marshmallows in just 16 hours. I must say that I don't have many regrets after the fact, the doctors at my local hospital has been running tests on me ever since I showed up 3 weeks ago after finishing the case. I haven't eaten anything since that sacred day, the doctors think that I consumed enough sugar to keep my heart pumping at a cool 175 beats per minute. They tell me that if I move even a little that my heart rate could spike somewhere into the mid two hundreds. All and all I must say that eating the entire 40 pound case of dehydrated marshmallows has been the biggest life accomplishment that I will ever make." I think I'm going to be sick.
