I have been having what doctors call palpitations every day

Mental health should always be taken seriously and if you feel like there are things you are struggling with or that exercise or preventative measures on your own are enough, seeking medical help is always advised.

In regards to the keto diet and heart health, studies seem to indicate that benefits of the keto diet are short-lived. Generally, after the 12-month mark, benefits stall and adverse effects on the heart can present themselves:

Here is a snippet of the conclusion:
"Based on our review, within the first 6-12 months of initiating KD, transient decreases in blood pressure, triglycerides, and glycosylated hemoglobin, as well as increases in HDL and weight loss may be observed. However, the aforementioned effects are generally not seen after 12 months of therapy, as the changes reported in the studies we reviewed are not statistically significant. Further research is warranted to evaluate the long-term implications of KD. Despite the diet's favorable effect on HDL-C, the concomitant increases in LDL-C and very-low-density lipoproteins (VLDL) may lead to increased cardiovascular risks."

As you can see by a cursory read of the above citations, we're a long way from emerging from the woods on this topic. It is far to early to get off the fence and plant one's feet firmly one either side of it. More study is needed. So far, the people I have heeded, including Dr. Nadir Ali and Dr. Stephen Phinney, not to mention the 'Low Carb Down Under' series on YouTube, have convinced me that for some people, with some modicum of self-discipline and willingness to experiment, a low-carb/keto diet might just save their lives.

Start reading ACTIAL studies…..double blind studies, peer reviewed and published..

If you are eating the standard American diet of carbs you will have metabolic disorders including cancer, dementia and diabetes.

Please read the studies for actual tested information

Of course, the SAD is bad. All junk food is bad. But there are healthy carbs such as whole grains, fruits and veggies. I had a couple visiting one time, and I took them to the farmer's market that has incredible products. I showed her a beautiful pineapple and other items, and she exclaimed "Oh no!!! That is POISON to my body!!! I guarantee they had eaten a lot of garbage food in the past, but not fresh fruits and veggies.

I have PVC's, If your doctor wasn't worried you should be good. I've had them for about 15 years. At first I thought I was having a heart attack, Went to er and they said no, I then had a complete heart work up, echo, stress etc and the cardiologist told me I had GERD. My GERD happens to mimic Palps. She also told me I had PVC's but they were benign and that I was just one of the lucky ones that feel them. Not so lucky. They appear when I'm at rest. That's typical of them. She also told me many many people have them and they just don't feel them. Hasn't stopped me from heading to the er when I get all freaked out about them! My new cardiologist is wonderful. He's been very calming and really listens to me. I am seeing him again this Monday the 3rd. Just to talk about how this is impacting my mental health. Someone else on this group told me that an anti depressant helped them so I may go that route. Find a cardiologist that you feel is a good fit for you. Ask to have the stress test and all the other tests for your peace of mind. I had one doctor at an er tell me PVC's keep her in business, that's how common it is. Keep in touch and let me know how you do. Oh and freaking out only can make them worse. Ask your doctor for a script for Xanax. I take them as needed when I feel anxious and know I'm going to have trouble falling asleep.

I have the same problem. Just published my experience. My doctor referred me for an ablation, but I have PSVT and on medication. Still have the palpitations. Worse when I stress over something, I think partly due to anxiety, so I tried taking alprazolam and still get the palpitations, only I do not get so upset and scared. I am sorry you’re having palpitations, it can trally hinder on your quality of life

I have PSVT that gets triggered by PACs. A few years ago, I started a supplement that has definitely helped lessen the extra beats/palpitations. It’s l-theanine (NOT to be confused with threanine). Both are amino acids but they are different. I take 100-300 mg daily. L theanine is out there as a natural supplement to ease anxiety. Also used in dogs and cats for anxiety.
