The Keto Diet and Blood Pressure: What Does the Research Say?
It’s National High Blood Pressure Awareness Day!
The ketogenic diet can bring a myriad of health benefits as people replace heavy starches and sugars with healthy fats, proteins, and nutrient-dense lower carb foods. There are a lot of misconceptions about the effects of the ketogenic diet on heart health, so let’s discuss what the research says about the keto diet and blood pressure. You might be surprised to find out that studies show going keto might reduce blood pressure and minimize hypertension. [1]
What is Hypertension?
Hypertension is a common condition where the long-term force of blood against the artery walls is too high. This can lead to problems like heart disease [2]
Blood pressure is measured by the amount of blood the heart pumps and the amount of resistance to blood flow in the arteries. Blood pressure gets higher as the arteries narrow and the heart pumps more blood. Some people have hypertension without any symptoms.
The risk of hypertension can be reduced with a ketogenic diet. Promising studies continue to unveil how a reduction in carbohydrates and an increase in healthy fats can benefit the cardiovascular system.
What is Hypotension?
Hypotension refers to low blood pressure. For some people, low blood pressure doesn’t cause any issues, but for others, abnormally low blood pressure or hypotension can lead to dizziness and fainting [3].
Low blood pressure can be the result of certain medical conditions and dehydration. Symptoms of low blood pressure include nausea, fatigue, and blurred vision.
What About the Keto Diet and Blood Pressure?
Studies show the ketogenic diet can have a positive impact on blood pressure. Many people find their blood pressure regulates and improves with the keto diet.
Research reveals carbohydrate restriction decreases systolic and diastolic blood pressure in people who are overweight [4] [5] In other studies, higher doses of omega-3 fatty acids effectively lowered blood pressure [6].
Blood pressure has also been shown to elevate sugar consumption [7]. The ketogenic diet reduces sugar consumption, instead of focusing on healthy nutrients, protein, and fat.
Keto-Friendly Foods that Help with Blood Pressure
Some keto-friendly foods are also helpful for blood pressure, such as chia seeds and salmon. Studies point to improvements in blood pressure and a delay in the development of high blood pressure with the consumption of salmon and omega-3 fatty acids [8].

Been keto for about a year now, this morning my blood pressure without any food or coffee was 91/53.
I have only been on a keto diet for about 3 months now, and have lost a solid 20 lbs of fat in that time. From 190 to 170, male, 5’6″, age 69. But my blood pressure has increased from ~ 132/80 is to 143/90 in my ophmalmologist’s office this morning. She said she thinks I lost the weight too suddenly, and referred me to my primary care doctor … not a surprise, I had been noting the same changes in my monitor weekly at home. I’m a bit afraid when I see him he will tell me to stop.
My blood pressure before keto was healthy and hovered around 120/80; however, I was very surprised today (9 months into my strict keto and essentially paleo venture) to find that it was 102/68 at the doctor’s office. Female, 57, 5’7 1/2″, now 135 pounds.
Hello, I’ve been strict keto for 6 weeks and my blood pressure is 85/60 should I worry.
Would like to loose another 15 pounds. I am 53 years old.
I am very active.
I do my 10k steps every day
I started the keto diet about a week ago. This morning my blood pressure was 168/87. It was like that a week ago. It hasn’t gone down one bit although I lost about 4 pounds which I really didn’t want to since I only weighed 118 before starting the diet. I basically wanted the health benefits. I’m so confused now. Does it take a while before it has a positive effect on blood pressure?
I started Keto 3 weeks ago. I lost 7 lbs in the first week. My blood pressure went down so much my doctor told me to stop taking my blood pressure medicine. I gained all the weight back though. Even though I have followed the diet strictly using carb manager app. The reason for doing it was to loose weight. According to test strips I am in full ketosis. I am concerned about everything I’m reading about possible heart issues. Any advice on loosing weight?
I typically have blood pressure 140/111. I am on day 11 of healthy keto(eating salads wheat grass electrolytes) checking blood pressure past night (1 day after stopping carvididol) my blood pressure dropped to 85/75. I assumed it was a mistake so i tried multiple times and similar result. This morning it was a little higher but still really low. Not sure if i should be worried or not. Worth noting is my pulse rate seems to be higher as well
Hi Jeff! This is certainly a question for your doctor–feel free to give us an update regarding what he/she says.
My bp stayed low a little bit after stopping meds too then began to rise. Wonder if it maybe takes a bit to get the meds out of your system and thats why its lower at first
Keto helps substantially with my hypertension within a few days of starting (before significant weight loss has occurred). Gone from requiring lisinopril 20 mg twice a day, hctz/triamterene 75/50 twice a day & clonidine 0.1 mg in the morning (still high after waking up) to lisinopril 20 mg twice daily as a solo agent. And it has done that within a week.
Simply amazing the difference cutting carbs from my diet makes on my bp control. Still require medication, but much much less and control better on the simplified regimen with less drug.
I have been on the keto diet and asting lifestyle for 4 years. I have reversed my Stage 3 Chroni Kidney Disease, healed my back issues and decrease bot my blood pressure medicine and thyroid medicine. It works if you work it.
