When reducing unhealthy food in your diet, having less-bad alternatives to the unhealthy thing you're craving can be a big help as your metabolism adjusts to the new diet.

For a personal example I've been greatly reducing sugar in my diet and sometimes I just crave something sweet. I've found ice cream to be the least sugary option, and I consume less sugar by having a bowl of ice cream than I would by having a few chocolates. My wife has a significant soda drinking habit and when she really craves a soda she's been turning to the Poppi and Olipop sodas as less-bad alternatives
