Okay good, then you will agree that someone could easily eat solely fast food their entire life and have a better health profile than some organic moron seeking out GMO free foods. 
I don't know if they would have better health or if you are being sarcastic, but I can tell you this much: From my own experience I have maintained 5.5% bodyfat on 90% processed foods at times.
I also like to go through juicing phases (yeah, pun intended) Kale, Carrots, Apple, Ginger root and a Citrus fruit twice a day.
Shitload of water
Greek yogurt with Barley
That diet for me works wonders on mental health, energy and over-all well-being.
I never believed that food could make you feel a certain way. I read many of Jack Lalannes books... actually, I've read and studied everything you can imagine and even tried them out myself.
Jack was big into fresh fruits, veggies and wholesome foods. I scoffed at that for years as I taught my clients about proper nutrition.
I couldn't let their obese asses know that I was eating Ice Cream, candy, doughnuts.. etc, etc...
But here's the thing: I NEVER over-eat. So, there is some credence to just counting calories and remaining in a deficit.
As you age, things change. Lots of things.
Go for the better foods even if you can stay in shape on shit food. Trust me.
One day you will wake up with anxiety attacks and high blood pressure and find that after youve taken every calming drug under the sun, that food has so much more to do with your mental and physical health.
Our DNA replicated daily.... it replicates from the food you put in your pie-hole.
Think about it.
You wanna replicate shit or ....
I'm sure you get my over-exaggerated point.
Now, let's see if any of my other questions were answered.....
"all about them macros" is such a common saying these days... do they really know WTF they are talking about? Hmmmmmmm
