The vast majority of the studies mentioned in those videos are old, where most researchers could get away with hacking the P values [0]. A lot of studies done in the last decade contradict the older ones (the article I linked earlier is full of sources). Also correlation is not causation. In how many of those studies controlled the amount of carbs? Because the combination is very important [1] [0] https://www.youtube.com/watch?v=42QuXLucH3Q https://www.youtube.com/watch?v=42QuXLucH3Q [1] https://news.ycombinator.com/item?id=14831224 https://news.ycombinator.com/item?id=14831224 Edit: Looking at the last link of your first video, it acknowledges low carb diets are beneficial short and medium term, but there's very little literature for long term. It concludes low carbs are bad long term... but you must see the table on page 13 to see how they reached that conclusion. The "low carb score" group still had a crazily high 37-42% of carbs (compared to LCHF diets which are usually 5% carbs), it had more smokers and all of them had trans fats (very dangerous but can be easily avoided altogether).
