Q: Dear Dr. Sears,
I'm an Italian doctor and a happy "Zoner". What do you think about the use in the diet of the conjugated linoleic acid? What do you think about its lipogenic use? Thank you for your answer and for your Zone method!

Dear Sara,
A: Commercial sources of CLA contain two isomers of CLA, one of which appears to cause an increase in insulin resistance. I would not use any CLA supplements until one can be produced that contains only the single isomer that doesn’t have the adverse metabolic effects.
