    Fish and Leptin Sensitivity

    Interesting. This research suggests that a diet rich in fish could improve leptin sensitivity.


    Just my take:

    Could it be that fish could have this effect on humans because if grok and his tribe were to live by a lake/river etc. there would be a much more stable supply of food than if we had to go out and hunt which wasn't always successful? A diet rich in fish could signal to the body that there is a reliable source of food and thus increase leptin sensitivity decreasing appetite and ultimately that less body fat needs to be stored.

    Any thoughts? Quite interesting this whole leptin thing!

    This is very interesting as I seem to drop fat faster when eating a lot of fish. Maybe I'll try a salmon a day week challenge.
    Sometimes you need to be told the truth in order to be able to see it.

    Right well leptin signals to the brain and DHA is pretty ballin' for the brain. And EPA greatly reduces inflammation which I suspect is at the root of many diseases (amongst other things but inflammation is probably the heaviest hitter) so I'm not surprised.

    There really isn't much animal-based omega 3 in anyone's diet unless they buy pastured meat, take fish oil or eat fish. This was reflected in the study and I think that it's the best explanation

    Point of clarification: as I read the abstract, the study showed a difference in leptin levels, not leptin sensitivity. Current thinking is that most obese folks secrete plenty of leptin -- but their brains are resistant to the signal.
