The scientific community is drinking their own cool aid for so many years, it will be very hard for them to come out right and say, "we were wrong"... If such studies continue and the grass root movement towards lo-carb diets continue, I can see the scientific community taking a position that "lo-carb diets are bad for you, but probably better then being obese"..
This is still a far cry from admitting that this WOE is healthier then the low fat regiments we were sold over the past 30 years... It may take another 30 year to flip the food pyramid on its head...
