I'll often go 3-5 days where I only eat small quantities of fruits, vegetables, and nuts, operating in very much a calorie deficit. This has been a thing for years, and when I'm in this mode I don't really have much craving for food, it's kind of surprising to me. Energy levels are fine, I'm generally pretty physically active, it just seems normal and I enjoy the lightness. It's not a lack of appetite though, if I decide to pursue a large meal in this condition, my enthusiasm is high and I'll eat enough food to feed a family of four if I let it happen. But I've noticed if I instead eat more processed foods, especially refined carbohydrates, while trying to exist in this calorie deficit state similarly to my fruits/veggies/nuts mode, I'm miserable, irritable, and constantly craving more food. And it's not some mild craving, it's like craving an addictive drug. I hadn't considered if timing played any significant part in these experiences, what seems very obviously significant was the types of food.
