yeah, my takeaway comes from the suffering animals, not from a medical viewpoint.
But to see it from a medical viewpoint: I practiced the “paleo” diet for quite some time and had really good results with it. but honestly it was such a big constraint in my daily living because you’re not allowed to eat like 70% of the things that you ate before, you can’t eat out because there is always smth in the meal that isn’t allowed and so on.
low-carb high-fat or low-carb-high-fat-high-fiber is much easier but one also has to consider the science here, since lowcarb is marketed as the nonplusultra for everyone: if you’re fat or been on a very unhealthy diet for a long time you’re probably having already a less sensitive insulin feedback, low carb can re-establish this and will help you loose weight. If you’re not fat or insulin resistant, you can go for carbs too.
so from an evolutionary standpoint, I would refine, our bodies are designed to eat everything, but should do that in a balanced diet and not in extremes
