There was some guy on telly did a test.
Half the group had to eat oranges.
The other half had to drink orange juice.
Then swapped them over the next day.
I can't remember the exact setup but i think it was like 'eat/drink as much as you want, stop when you feel full'.

Everyone was able to consume far, far more calories in juice form and probably far more sugar than they needed.

I think like even eating enough oranges for 1x300ml glass was hard for many people to do in fruit form.
Basically, the rest of the orange filled them up and that's what we're better evolved for: slower digestion of a more varied mush and lots of fibre and stuff like that.

The juice is far too easy for us to eat way more than needed.
