My understanding of this is:
1) Body can't burn fat when blood sugar is high/insulin spiked
2) Gh converts fat cells into glucose so they are available for use as fuel
3) Converting fat to more glucose when bg is already high creates further insulin pike, and prevents converted fat cells from being stored.
I would LOVE to be wrong about this and be able to run some gh rn, so if somebody knows better and can correct me, PLEASE do.
Some one other than me should address this because I dont know whats right now lol
