But your first point already admits an energy surplus while this thread is talking about a negative effect supposedly modulated by a glucose/insulin spike in isolation.
You're just dolling up a trivial claim that excess energy causes obesity, or you're suggesting that excess energy consumption without a glucose spike (like gulping down butter) somehow wouldn't lead to obesity.
GP asked for causal rather than correlational links for non-diabetics, which I provided.
But you are right that a lot of the health problems are caused through obesity; I will not deny that.
The thing with gulping down butter is that almost nobody does that, because it quickly leads to satiety and does not trigger the desire to eat (or drink) more.
