It would make more sense for the pubs etc to open at 11am and NOT close any sales outlets at 2p.m to 5p.m. As for 4a.m. closure, IMO, it would not be my cup of tea, especially if loud music was still being played.
My whole food plant based diet means that oils and processed packaged foods are likewise excluded. But vitamin B12 is required.
I cook a spicy veggie soup, followed by a veggie salad and completed with fruit and various nuts in a six hour window, and apart from green tea that's it for the day.
No dairy, no meat eaten, and it's no business of mine what people think of me.
