I don't know about caffeine acting as either an appetite suppressant or activator in different people. I would say that caffeine is certainly not something to be afraid of while you're dieting. Most diet supplements have some form of caffeine (guarana and ma huang are other natural caffeine sources), and the reason for this is not just to 'amp you up,' but that from the research I've done, it appears that caffeine does assist in releasing fat into your blood stream, so it can be effective as an addition to weight loss. As far as cortisol is concerned, sure - caffeine can impact cortisol levels. However, again, from the research I've done that cortisol impact actually levels out and is much less of a factor for folks that take in caffeine regularly - but it's still a factor. here's a very boring article for you (just read the abstract and you're probably good): At the end of the day, I think it's really easy to overthink caffeine as some sort of magic answer, as if to either add it or remove it from your diet will suddenly make your body fat evaporate. Personally I'd recommend exploring caffeine as a supplement to anyone who is exercising regularly (and I mean 'really exercising,' not a walk around the neighborhood), but I'm not a doctor and my opinions should not be taken as medical advice. I think the answer is that just like almost everything else, it's just a thing with good points and not-so-good points, just like most everything else. :-) Regards, Phil (enjoying a great cup of freshly ground Peet's, by the way, LOL) --- On Sun, 1/31/10, Julie Armstrong <mxsjwl@gmail.com> wrote:
