My aunt was (she died a few years ago after a long battle with cancer) 8 years old than me. She was wonderful person that everyone liked. Growing up, she still had to follow house rules. Back then, her life depended on it. I would sit down with your sister and let her know the house rules. If she lives there she must follow them. Preface it with, "I'm here to keep you safe and as happy as I can, but in this house we follow certain rules". The rules should revolve around keeping herself healthy (good sleep and eating properly) and happy (being sleep-deprived, she's like a jerk). Perhaps, you can agree on a happy medium. Say a later bedtime, but she doesn't have to eat breakfast and she has to eat a healthy lunch/dinner? She needs a parent, not a friend.
But what she has is a sister. A sister is not a parent. A sister is not a friend. And an older sister probably can't suddenly step into the role of parent of a younger sister, when the younger sister is 14, in the way that she might have been able to when the younger sister was younger.
