37% of your dietary intake from carbs is not low carb.
And really 100 g/day is a lot. Most people on "low carb" diets are going to be eating half or a quarter of that.
So, this is just more ridiculous nutrition research funded by the US government, produced by academia.
They made up their own definition of "low carb", then people who read the results get confused and try to apply the conclusions to actual "low carb" diets.
