That's good to hear -- I also wonder it myself, I find it hard to believe that hunger just disappears, I think people probably mean that something else compensates for it. Just like I feel "amazing" while hiking, it's mostly that the breahtaking views and hormones and brain chemicals overtake the soreness, swelling of legs, and very often the unbearable heat and mosquitoes.
But "luckily" I have a lot of fat and weight to lose, so I'll try it myself after the holidays and see if it's true or not in my case.
