@Alecmcq Yes, I am bit surprised as well! I’ve done some extensive searches on Metoprolol, Lisinopril and Amlodipine in terms of Keto, weight, insulin. I haven’t found much. One or two studies here and there about something else that implies beta blockers and ace inhibitors mildly interfere with weight/glucose control and a few comments pro and con on Reddit from unauthoritative sources.
I do have a feeling they might be the problem. I tried a self experiment of cutting doses in half for about two weeks to see if there would be a weight change and/or blood glucose/keytone level change. I think there was a small rise in ketones in that period (went from a stead 0.4 to a steady 0.5) but little else. And my blood pressure did start rising again into bad territory. So I stopped the experiment. BP back to normal.
It’s a bit of a conundrum. MY BP has gotten better because I have stopped insulin from racing through my blood constantly at high levels. But I haven’t lost enough weight to have normal BP without meds quite yet. But if the BP meds are interfering with weight loss it is a catch-22 !
Oh, and yeah, I can’t get help from my GP or cardiologist. They are both very anti-keto and wont get very involved in any conversation like this before they turn to the ‘keto is very bad for your heart’ muck.
