I will add to this that WORST case if you just eliminated fast food and Soda / fruit drinks you’d almost automatically be eating healthy.
I don’t eat like a rabbit, but just not indulging in the bottom tier garbage keeps me heathy while still enjoying my food.
I will agree with OP that there is a threshold where you try to eliminate every single bad thing where it just becomes exhausting and hinders enjoyment of life. But that’s way down the line.
Start without McDonald’s and Coke and see where life takes you.
