What is a fad, I would argue a 60% based carb die is a fad of modern times my grandparents would never have eaten that and heir generation were far less heavy and far less obese.
In addition to BigJims major point.
There is the secondary point of failing to discriminate between processed carbs and natural carbs.
The potato is a recent visitor to our shores, and white flour is a newer ingredient than wholegrains.
Complex carbohydrates, surrounded by roughage, fibre, minerals and vitamins were eaten in large quantities by our leaner ancestors and in proportions which suited their energy outputs.
Conjecture about past diets and their effects is good, just so long as nothing violates the law of conservation of energy.
