One of our IRSPT students asked me to comment on the impact of saturated fats on insulin resistance.  There are people who claim it’s not sugar that causes insulin resistance , its fat, especially saturated fat.

I think the answer is a bit more complex than people make it out to be.  Oxidized fats, poor quality fates, and too much omega 6 and saturated fats certainly have an impact.

I plan to write  more in-depth article about this, and to comment on the articles below .

I’d love your opinion about these
