My husband has a very stressful and dangerous job so there are times when he craves junk food to reward himself in sorts. In those cases I tell him go ahead and buy it but I don’t want anything or maybe a drink. I understand him craving it at times but I don’t partake. Another option is if he lets say wants to buy pizza, most pizza places have decent salads. Jett’s for example. When my husband craves Jett’s I tell him to get me a salad. I eat half and take half to lunch next day. You kind of eat from the same take out place just not the same foods.
