From the second article:

"The relationship between low-carb diets and diabetes risk isn’t as straightforward as it might seem at first glance. The researchers also note that this is an observational study and cannot prove that low-carb diets directly cause an increased diabetes risk."

"Interestingly, the group with the highest LCD scores (meaning they ate the fewest carbs) consumed about 37.5% of their calories from carbohydrates. In contrast, the group with the lowest LCD scores got about 55.4% of their calories from carbs." (wasn't even low carb to begin with - just "low-er carb = probably not enough to lower insulin levels significantly)

"The study also found some differences in lifestyle factors across the low-carbohydrate diet score groups. For example, the group with the highest scores had a higher proportion of current smokers, individuals with obesity, and lower physical activity levels compared to other groups" (lots of confounding variables in a epidemiological type study = very poor quality evidence).

I personally have reversed my type II diabetes of approximately 35 years duration eating low carb. Got off 4 shots of insulin, diabetic medicines and blood pressure medicines. Don't need any of them on a very low carb diet (generally 20 grams of carbs or less a day). Seems like the exact opposite of what the article suggests. So I have a hard time believing the study has much relevance to reality. But headlines get clicks.
