Totally same, if habitually snacking I can feel from "hungry" to lightheaded and shaky after a few hours of unplanned break, but when adjusted to 1-2 bigger healthier (less carbs) meals per day after a while my body is fine with 15 hour breaks and even more. At extreme I can feel physically weaker but not hungry. So "longer fast = more hunger" is definitely false for me and I guess depends on judges habitual schedule, physical activity and diet.
