When you don't eat things that your body needs to function your blood sugar levels get out of whack. If you were craving candy after a couple of days of not eating right, then your blood sugar levels were probably low and your body needed sugar to level. When you eat a diet of sugar, then you start craving salt to balance out the sugar, which is where the chip craving comes in. I ate a crap ton of chocolate over the holiday because my job had the brilliant idea of hosting a dessert potluck. I ate way too much chocolate and had to balance that with chips. Real food is your best bet if you can manage it when you get to that state. Specifically you want to go with proteins and healthy sugars, but since you hadn't eaten a solid meal in a while you want to make your meals light. The strawberries were fine, but in the future you might add like a piece of toast and a boiled egg to help stabilize and then slowly work your way up to more balanced meals. You can eat healthy without starving yourself, and you'll do less damage to your system if you do that.
