As stated above. I can go months without eating an egg, for example, and suddenly crave eggs benedict for breakfast everyday.
Good thing is my dietitian is aware of this executive dysfunction/quirk/habit and works closely with me to help me out planning meals in a way that works me.
Right now I am on a soup kick: Soup, soup, soup everyday, all day.
ETA A word
Oh I hear you. My dietitian plans my meals for me and that can be both a blessing and a curse. I try to find middle ground between sticking to my meal plan and eating soup everyday lol.
