I definitely agree with you but at the same time she's not showing how much of these meals she's actually eating. As healthy and well proportioned they are, her vlogs still don't show the whole story
From her vlogs, I get a very sincere and honest vibe. I genuinely don't think that she would try to 'fool' us by saying 'omg look at how much i'm eating' (obviously not in that way), and then eat a quarter of it. I get the impression that she wants to stay true to herself as much as possible
I originally thought she would have a very stuck-up personality (it's the 'vibe' her face gave me, obviously a wrong impression), but from what I can see, I really like her personality and her honesty. It's very refreshing, and she seems to have a very positive and balanced life view in general.
Most of what she eats is quite wholesome and healthy, I reckon she just works out enough to counterbalance
