There is a great discussion thread for Croissant Diet/ROS Theory of Obesity/SCD1 Theory of Obesity over on reddit.
u/Magnum2684 posted a list of additional things that can affect SCD1 levels. It’s a bit confusing to me – when they say “positive” they mean “reduces SCD1 expression” and when they say “negative” they mean “increases SCD1 expression”. Interesting stuff, though!
Here is a great summary of all three scd1 parts. Amazed and grateful that someone went through all the effort:
