I don't think that's feasible if a nominal portion is ~80g.
1.6kg produce in a day...
I'm working on handfuls. I weighed my breakfast after draining the excess water and it was 1.2kg. That was brown rice, red lentils, mushrooms, spring greens, carrot, quinoa, raisins, and herbs/spices. While it was cooking I had some fruit, apple, orange, banana, and some nuts.
I'd have that twice a day, sometimes three, changing the ingredients, and fit in a bowl of oat porridge with berries and raisins/currants.
Plus more fruit in between and maybe some whole meal toast with jam/marmalade/marmite.
