Lara Briden's Forum

After reading Lara's Blog # 6 on insulin resistance, I came across an article that mentioned the fact that higher levels of progesterone in the Luteal Phase decrease insulin sensitivity.

I'd really like to know if this is in fact correct.

Thank you

There's been some debate about that and conflicting results. I suspect the direct effect of progesterone is that it does slightly decrease insulin sensitivity, but at the same time, progesterone can have an important testosterone-lowering effect (see my cyclic progesterone blog post). Progesterone also increases metabolic rate, so those two latter effects mean it indirectly improves insulin sensitivity.
