the "daily liver flush" which consists in lemon juice, spring water and olive oil
If the theory is true that oil coats the insulin receptors which blocks ability to attach to Sugar molecules, then look what you are doing. You're mixing a lot of Sugar (the lemon juice) with lots of oil.
Btw, I've done two of those flushes and I think they are mostly bunk. All those green globules that came out of me were just a mixture of the oil consumed and bile. Nothing that was hardened came out.
