You are the expert of your body. Like @evelyntribole says, you can eat pumpkin pie for breakfast if you want to. If that’s what your body is hungry for, then go for it! It doesn’t have to be the weekend, or a holiday, to eat those foods you crave, like or want. In fact, if you eat them regularly, your body becomes habituated to them and they lose their stance on the pedestal. All foods are morally equivalent, no one food is better than another. Obviously, the nutrition breakdown varies by food choice, but thats a story for another post. Long story short, eat the apple and oatmeal if you want that. Or, eat the donut or cinnamon bun if you want that. Your body is smart, there’s probably a reason it wants one food over another!
