Caffeine tolerance and fat burning

  1. Caffeine tolerance and fat burning


    The longer we take caffeine, the more we need to take - to get a stim effect. How much does the fat burning effect diminish as the stim feeling gets less and less noticeable with the same amount of caffeine? Is it the less we (mentally) feel it, the less it's working?


  2. The fat burning effect generally does not diminish, but since most of caffeine's effects are from appetite suppression, that does diminish

    Couldn't it be from increased metabolism?

    AMPk is something I've been looking more into recently, so pardon an ignorant question..

    How strong does caffeine activate AMPk? How dose dependent is it?

  8. Caffeine elevates/releases blood sugar. In some, it will be enough to force the release of insulin, then the sugar rollar coaster ride ensures. End result, appetite increase. Also "one" of the reasons people crash a few hours after some short-acting stims; not just b/c the stim runs out but because of the sugar crash (acute hypoglycemia).

    Coffee can increase insulin sensitivity but that doesnt mean it cannot do the aforementioned "acutely" as well.

    No, too mild

    Caffeine isn't a very strong inducer of AMPK, clinically. But its effect is systemic and generally positive, which is nice

    Caffeine has consistently demonstrated to barely affect blood glucose and to have virtually no effect on insulin. The exception being megadoses (400mg - 800mg).
