I think that's because diet is only expected to reduce a bg by a small percentage (nhs data, I guess. Not lchf data). As of metformin so their thinking is both might actually get their very very high bgs into a less dangerous level.I think the other thing we need to ponder is how many newly diagnosed T2s are given the option to try diet only initially. Until recently, I would say the majority of those diagnosed went directly to Metformin.
I don't have any studies to back that up; it's more my sense of what I see "walk through the door".
Do prediabetics get offered metformin? I'd like to think just offered diet control. I guess the higher the hba1c the more likelihood of meds too?
They have to act if hba1c extremely high rather than wait for weeks for even low carb to kick in, maybe?
Lets not forget hba1c doesn't give the full picture, just the average. Bgs will be on occasion higher and lower than hba1c level. Quite scarey really on reading some people's first hba1c result.
