Yes — many people have. Blood pressure normalisation is one of the most frequently reported outcomes in fasting communities, and it is one of the benefits that researchers have also documented in clinical studies. But the process is not something to approach on your own, and it requires working closely with your doctor.
Intermittent fasting reduces blood pressure through multiple overlapping mechanisms — lower insulin, weight loss, reduced inflammation, and improved vascular function. Many people who fast consistently over several months see blood pressure drop enough that their doctors voluntarily reduce or discontinue medication. This is not rare. But stopping or reducing medication must always be done under medical supervision.
Blood pressure is not just about salt intake. It is closely tied to insulin levels, inflammation, body weight, and vascular health — all of which fasting directly influences.
Insulin and blood pressure are connected. High insulin causes the kidneys to retain sodium, which raises blood pressure. When fasting lowers insulin, the kidneys begin excreting more sodium and fluid — often producing a noticeable drop in blood pressure within the first few weeks.
Weight loss reduces strain on the cardiovascular system. Even modest weight loss of 5–10% of body weight is associated with meaningful reductions in blood pressure. Fasting, when done consistently with clean eating, typically produces steady fat loss over months — and blood pressure often tracks it downward.
Inflammation drops. Chronic low-grade inflammation damages blood vessel walls, reducing their flexibility and driving up pressure. Fasting reliably reduces markers of inflammation, including CRP and interleukin-6, which may be one reason vascular health improves with sustained fasting practice.
The author of Intermittent Fasting in Practice received thousands of transformation reports from students. Blood pressure normalisation — including reductions significant enough to prompt medication reviews — was among the most consistently reported outcomes, alongside weight loss, fatty liver reversal, and improved blood sugar.
Clinical studies on intermittent fasting and blood pressure have generally shown moderate but consistent reductions. Early time-restricted eating studies have documented drops of 3–8 mmHg in systolic blood pressure over periods of 10–20 weeks. This might seem modest, but at a population level, a 5 mmHg reduction in systolic pressure is associated with a significant decrease in cardiovascular risk.
Studies on alternate day fasting and 5:2 protocols have shown similar or slightly larger effects, particularly in people who were hypertensive at baseline. The combination of weight loss, lower insulin, and reduced inflammation appears to have an additive effect on blood pressure.
Results are not immediate. Most people who see meaningful blood pressure reductions report them after two to four months of consistent fasting. The first few weeks often show a small initial drop from water loss and lower insulin — but the more significant reductions come from sustained fat loss and vascular improvements over months.
Common patterns reported in fasting communities:
This point cannot be stressed enough. Blood pressure medications have real interactions with fasting physiology. Some medications work in part by retaining or excreting fluids — fasting changes this balance. Others can push blood pressure too low if fasting is simultaneously lowering it through different mechanisms.
Never stop or reduce blood pressure medication on your own. The correct approach:
Many doctors — when shown a three-month log of consistently lower readings — will initiate the conversation about reducing medication themselves.
