We have a pretty decent cuff at home, so I have been keeping an eye on my blood pressure. I forgot to take a reading before starting, but I was around 120/76 in Feb.
While doing restrictive keto in July, my blood pressure came in at around 110/72.
Unfortunately I've got a stomach irritation, and I've been tending towards plain foods like rice and potatoes again, because they're easier to digest. Blood pressure has risen to 125/76 after 3 weeks.
I can't rule out that being ill has pushed my blood pressure up a bit, but I've gone from good to optimal to slightly elevated, and the major change is carbs...
