All of the sugar/processed foods that she consumes is aging her. Big Fella and Dense are good examples of "you are what you eat". It's also contributes to her feeling sluggish, oversleeping, headaches, moods etc..(excluding her bitchy, I am queen attitude. Thats all her) The human body is like a machine. Feed it nutritional food and it will do amazing things. (I've been doing a lot of research on nutrition and just how bad sugar/processed foods really are.)
I might be inclined to watch their channel if they focused more on "how to eat healthy/lose weight while enjoying a theme park. But that would actually take effort, commitment, and planning. I'm sure that's "just not their thing".
