Its not that I think an ancestral perspective is a bad one. Its just that: - existing hunter-gatherers have a bewildering array of different diets, many of them high in carbs and vegetation. - wild meat is very different from farmed meat (yes, even grass-fed beef) - it has way less saturated fat, to begin with. - When do you stop the clock on evolution? My ancestors were almost certainly peasants. Probably so were yours. So while they weren't eating modern ultra-processed food, they were probably eating closer to a whole-foods based vegan/vegetarian diet on a daily basis, with meat on special occasions - for thousands of years. My pet theory is that, to the extent that Paleo, Low Carb, but also Whole Foods Vegan diets work, its because they all cut out ultra-processed foods. However, to the extent that sellers of ultra-processed foods can catch up and start selling you processed keto foods etc., these diets will stop working.
