I would echo (below*) what Dr. Attia had to say in his review about different diets like the consumer reports article and the chart (with those mysterious carbohydrate allowances) in which he himself is hard pressed to admit the correlations and causation because I think he fears being censored by peers? And who wants the Corn Growers Association and Sugar Cane & Beet Sugar INDUSTRIES up in their face (clandestine) 24/7?
Carbohydrate intake DOES NOT MATTER!
*It is the reduction of highly refined carbohydrates and refined sugars like sucrose and fructose (HFCS)? (i.e. a classification of a type of substance or compound)
If we were not intended to eat carbohydrates then why is the first thing secreted by the salivary glands amylase? (probably for digesting raw starches and natural sugars)
I have a lot more to say about this but will save for a later time!
