Greens are a source of protein, most whole foods are. But if you ate only greens I highly doubt you’d be able to eat enough calories, and you might run into other issues like mineral toxicity. Calorie bombs get a bad rep but the human diet revolves around them, the problem is many get them in the form of refined sugars and fats.
I don’t think such a diet would actually be considered very healthy to be honest, wouldn’t one at least need a protein source?
