That's such great news. I am really new to this and am doing mostly paleo type eating but fairly relaxed with dairy and a bit of fruit now and again

I have been borderline high BP 150/100 ish for a while with a doctor talking vaguely about meds but I was clear I did not want to go there.
Have been eating this way for about 3 weeks and dropped 12lbs already so am hoping to see a BP change as well. How long before there was a drop in numbers would you say?
