Why forbidden junk retaliate deprivation revolt craving?

All I can think about as I commit to a salad is pizza. This is an archetypal revolt against the perceived deprivation, as we see in meditation. The junk food being forbidden makes it all the more desirable. The image of healthy eating in my mind is that of punishment, and the craving is its mechanism of retaliation against what it feels is its liberty and enjoyment.
