    Theres something I dont get.

    Yesterday I almost didnt ate. And as it got late I couldnt eat because my roomie's dad slept over on our couch so I didnt want to wake him by making food. Yet I was STARVING to the point I was dreaming of food :P

    So I slept 8 hours and woke up - and I was so looking forward to eat! Yet now my hunger was completely gone and Im not hungry at all.

    The body signals to your brain that you need food, yet sleep removes this hunger craving alltogether. Ofcourse I had to eat abit but got stuffed fast, and I feel I didnt get to eat half of what the body actually needed regarding how hungry I was last night. Logic would imply that the longer time not eating, the more you will need to compensate - or/and that the hunger level will only increase.

    Yet after sleep, my hunger level kinda of reset completely.
    (Im 75kg, 184cm tall - not obese at all but rather abit skinny - if that counts in any way)

    Is the hunger removal/reset after sleep an evolutionary "mechanic" not to harm organisms from suffering the ill effects of lack of nourishment (By being physically bothered by lack of food) in order to hunt food effectively or something?

    You have to remember that for most people in most of history there were always times when food was less plentiful. It's a basic mechanism to be hungry when you need to eat, but if the food doesn't arrive and doesn't look like arriving, the signals just fade a bit.

    What I find at times like that is that if someone else prepares some food and puts it in front of me, I might not feel like eating, but start with a few mouthfuls to 'be polite' and appetite returns and I enjoy the rest of it.

    Hi Raziell,

    It would make intuitive sense for the cessation of hunger signals to provide an evolutionary advantages - it is difficult to concentrate on gathering berries or hunting prey when hungry (i would imagine - never actually tried! ).

    I can empathise with you; i normally eat the same meal at the exact same time (11am) every day (prefer my digestive system to know what to expect ). Today i had to skip eating at this time and felt a bit spaced out come lunch time. However, the hunger shortly subsided.

    Here is a link to a review on appetite regulation - Interacting appetite-regulating pathways in the hypothalamic regulation of body weight. - Abstract - UK PubMed Central

    Best wishes,

    Tridimity
