In detox I just eat whatever I have to/can to get through. The first month I try to stay away from sugar but if I'm having an intense craving I feed it what it needs (anything other than alcohol ). After that I know from experience, for me, the sugar and carbs long term increase my cravings by spiking and crashing my insulin (and I'm talking all carbs, even fruit and juice). So I really try to stick to a Paleo approach (I'm doing ketogenic right now just for laughs...I like to focus on things). But healthy fat and protein do better to alleviate cravings overall. That takes care of the physical side. If its psychological I try to pinpoint what is driving the craving....often times deep breathing, yoga or other exercise handle it nicely.
