For my understanding this is mostly attributed to insuline resistance vs sensitivity. As you get older and overexposed to sugar, your resistance raises and in order to reverse a lot of the internal inflammations your body has produced from over-intake of sugar you need to force ketosis and burn calories with a low-carb diet. This in turn helps reduce internal fat and repair organ functions, fundamentally restoring hormone production and refreshing your brain as well.

It does not mean that carbs in general are toxic, nor that this diet is recommended for everybody! Diets are very personal, it just becomes more and more common because sugar is added everywhere, people are getting older and older and obesity is a global problem. As such, most people are very insulin resistant and work better with low-carb/high-fat diets.

This headline is one of the reasons there is so much misinformation in food and diets
