I like low carb diet, but I think when people jump to primal arguments, they also forget that primal times you didn't have a constant, easy, cheap food source at your disposal 24/7. At some point, things like fasting and reduced calorie intake combined with something low carb is probably closest to "primal" diets. Making pancakes with almond flour isn't. If more people went without food somewhat regularly, they would probably be better off than they are eating 2000+ calories a day like people do now. Macronutrients do matter, but volume matters as well. In my experience, higher fat diets keep you from eating as much, so you naturally get fewer calories and thus you lose weight. If you could eat a high fat diet with 8000 calories a day, you'd still get fat, but my guess is that when people consciously eat a high fat diet, they are going to end up eating say 300-500 calories a day less over time, and that gives a significant advantage over a period of months or years.
