You are probably downvoted because there isn't enough convincing evidence for insulin hypothesis. I like Jason Fung and I love the idea of fasting for health and weight-loss. I think though that advocates of both fasting and low-carb make a mistake getting too attached to insulin. They may die on this hill while being right all along but for different reasons.

My understanding is that we don't know if it's insulin or something else that makes many people wanting to eat less once they are accustomed to regular fasting or low-carb diet. It would be better to focus on a proven fact that it does work for many people and trying to understand the mechanism instead of picking just one possible one (insulin) and staking everything on that being full explanation.
