Lesson 68: Advanced English Speaking / Idioms - Phrasal verbs

My closest cousin EATS LIKE A PIG but is still as SKINNY AS A BEANPOLE. I’m happy for her. I really am. But what really frustrates me the most is that I look like a pig when I EAT LIKE BIRD. My situation is getting worse and I feel like things are GOING DOWNHILL for me since I keep PUTTING ON a few pounds every month. It is unfair. If you ask me about the one thing I would die to know it would be how some people get to enjoy any meal, whether healthy or not, and still be FIT AS A FIDDLE. I want to be like those people. One day I want to feel that I can have both: a great body that looks good in anything and enjoys food all day long and EAT UP everything and anything I want. If this wish comes true I guess I would be the happiest person on earth. I will spend my time ORDERING IN, and getting TAKE OUT on the weekdays and shopping for all kinds of clothes on the weekends.
