This smells to me like a bit of anti-keto propaganda subtly inserted into the world by the multi-trillion dollar carb and carb consequence industry.
Here’s the second paragraph:
“Right now, low-carb diets, like paleo and keto, are one of the hottest trends. But two recent studies looked at the relationship between low-carb diets and lifespans. Even though low-carb diets have been shown to shave off pounds, it also now appears that adhering to these diets for long periods of time may be correlated to a higher-than-average risk of dying earlier from complications like heart disease. In 15 years, we might look back at the 2010s as that time we all freaked out about carbs for no reason.”
