That is no joke. My metabolism is fairly high due to strenuous regular workouts. All week long when at work, I eat almost every 2-3 hours. Heck, I eat breakfast as soon as I wake up, and eat a snack right before bed. If I have a weird day on the weekend where I am not eating enough food, and out hiking or something most of the day, I can wake up 3-4 lbs lighter the next day. I would be in big trouble in a SHTF situation if I could not find food.
