You're reading too much into what I said. None of your claims actually contradict mine. This part actually supports what I said: Fat and protein are not an optimal source of energy and its use as such will force the body to open up certain pathways that are metabolically inefficient and potentially ruinous in the long term. Yes, that's exactly why low-carb diets work. They force your body to use a less efficient fuel, which is an effective way to counteract the problem of having too much fuel. And while ketogenic dieting may be "potentially" ruinous in the long term, obesity is definitely ruinous in the long term. I'm not really a pro-keto person, I think strict keto diets are too extreme for the long term. On the other hand, it's evident that a high carbohydrate diet provides energy that is excessive and unsuited for modern, sedentary lifestyles. Most of us would be a lot less overweight if we simply ate fewer carbs (like <40% of total calories)
