7. High Fat Diet = Ketogenic Diet?

Updated: Jun 9, 2023

@ 3:22 Dr. Diamond’s mentioned about his previous research involving stress and nutrition, and further investigation of the impacts of a “high fat” versus “ketogenic” diet. He published a paper in 2005 titled "Combination of high fat diet and chronic stress retracts hippocampal dendrites". In the paper, he showed that high saturated fat (lard + coconut oil) diet plus stress produces atrophy in mice's brain. Later he found he was ignoring the fact that 25% of the calorie actually came from sugar. Because the demon on the plate was the fat, it made people easily to ignore the fact that the diet was actually a sugar fat diet but not a low sugar high fat diet. After realizing this, he ran a study with 50 randomly picked papers with "high fat diet" in the title. All 50 papers showed negative effect and all 50 papers used a method of combination of fat and sugar. He also searched 50 other papers with "ketogenic diet" in the title. All 50 papers showed either neutral effect or benefit. What is important is that ketogenic had no sugar. Very interesting. I will be very careful with the "high fat" research and double check on the sugar part from now on. On the other hand, it does show that combining high fat and high sugar is dangerous, it is worse than having either high fat or high sugar by itself.
