When I eat healthy=

my skin has more colour
I am less depressed
I have more energy
I shit regularly
I sleep better
my farts don't smell

So yes, very much I notice the difference when I don't eat well, compared to when I do.

I eat loads of green vegetable mostly spinach, home cooked indian cuisine, tofu, boiled potatoes and I drink plenty of green tea.

In the morning ideally I like to have a hemp seed bar with a few mugs of black tea, or milky chai, depending on my mood.
