7 Reasons to Eat More Saturated Fat

Tim Ferris is best known for his book The Four Hour Workweek, which introduced the world to what he calls “lifestyle design”. The idea is that people grow up hearing all kinds of advice about how they should live their lives, but no one ever experiments to see which advice is actually useful. So that’s exactly what he does.


He has experimented with different negotiating tactics when buying advertising. Outsourced the search for a girlfriend. (It worked.) Messed with his sleep cycle to see how much he really needs. He’s even tried intentionally mistreating friends to see how they react. (Not recommended for everyone, by the way.)

His willingness to question conventional wisdom has lead him to some of the same conclusions about diet that I have. Namely, that our thinking on fat is generally a mess, driven more by agribusiness advertising than by science.

Ferris’ latest post is a preview from an upcoming book, The 6-Week Cure for the Middle-Aged Middle: The Simple Plan to Flatten Your Belly Fast!, by Dr. Michael Eades.

Go read the whole preview, it’s quick and interesting. I just want to highlight one part.

You will likely be astounded to learn that your brain is mainly made of fat and cholesterol. Though many people are now familiar with the importance of the highly unsaturated essential fatty acids found in cold-water fish (EPA and DHA) for normal brain and nerve function, the lion’s share of the fatty acids in the brain are actually saturated. A diet that skimps on healthy saturated fats robs your brain of the raw materials it needs to function optimally.

The story about fat consumption isn’t just about weight loss and heart disease. Cutting out saturated fat from our diets means we can’t even think properly any more.
