Its pretty well understood that a diet that is high in carbs and low in nutrients is generally unhealthy. Our bodies are totally capable of generating all of the glucose/ATP they need from a diet that is high in protein and fats and these diets tend to be more nutrient rich as fats and proteins (in general) are found in more complex foods. Our bodies cannot, however, produce all of the nutrients we need from a diet that is high in carbs but deficient in other things like proteins. And yes there is always a change that future work will require us to rework our current understanding, thats how science works after all.
