Since the topic has switch over to diet (somewhat), I would like to share my experiences with dieting, having lost 50 lbs and plan to lose another 35 lbs. For me, the craving to binge comes after a free meal or after several 3-5 days of no free meals. On RFL, I consume around 900-1000 cals daily, and I find the cravings come for junk food, like burgers, shakes, sweets, etc, and not an actual hunger for any food.
When these cravings come, I like to detach and observe them. They can be very telling. They seek pleasure and contentment for an overabundance of food and usually don't stop unless I stop them.
