More likely, as measured how? How do you know this? Spending more time thinking about my condition is a great way to improve blood glucose control, at least in my experience.
I know this because I know diabetics who have lapsed out of control, or retreated into a rather small life, because they felt the excessive personal rules they’d either self-imposed or been taught by others were burdensome. When possible, teaching them a lighter set of principles to follow has had a positive effect.
