You should not drink Coke because it has WAY too much sugar and WAY too little of anything beneficial. If you tried to consume the amount of sugar in Coke by eating apples, you would be too full long before you get to Coke-level sugar intake. That's because of all the other stuff in an apple; it's not concentrated sugar.
Your body is a wonderful thing. Respect it and listen to it, it will keep you healthy. That's literally its job, and it only knows how to repair and heal you. It will keep the things it needs, and discard the rest. You can't "over-consume" if you eat real foods. Your body won't let you; you'll get full and stop. You can only over-eat engineered foods, which over-saturate sugar|fat|carbs|salt|etc, which then necessitates a "diet".
The word "diet" is not always about restriction. Surely you've heard people use the term "standard American diet" which doesn't have anything to do with restriction.
I assume you are talking about a raw diet (not necessarily calorie restricted diet) because of your comment about minimizing steps between soil and mouth.
There's an episode of Mad Men where they are coming up with pitches for weight loss products and losing weight is referred to as "reducing", a term from before the word "diet" was used as you've described.
Have you tested this?
Taking plants from the soil, or fruits from the tree/vine, and trimming, washing, cutting, and cooking are typically considered steps that are unavoidable for some plants.
The difference between a baked potato, potato chips, and Pringles is what we're talking about. The oil used for potato chips (and Pringles) originated from plants, but it has undergone several steps from plant to container of oil.
I don't know about Pringles / Lays &c, but I've never seen two potatoes of the same size and shape in a bag, so there must be some way they manage to get all their chips to look the same.
Lays and nearly every other brand are just thinner versions of potato chips you could make yourself at home (cut thin, fry in oil, dress in salt). Nothing "blown to smithereens" there.
