High blood pressure affects millions of people around the world and is one of the leading causes of heart attacks, strokes, and kidney disease.
Doctors have long warned that eating too much salt can raise blood pressure, and many patients are advised to cut back on salty foods.
However, for many people, lowering salt alone only leads to small improvements. This has left researchers wondering why high blood pressure often remains stubbornly high, even when people follow standard dietary advice.
Scientists from Pantox Laboratories now suggest that the problem may go deeper than salt alone. According to their research, salt may work together with other parts of the modern diet to create harmful metabolic cycles inside the body.
Once these cycles begin, they can keep blood pressure high even if salt intake is reduced. This could explain why many people struggle to control their blood pressure through diet changes alone.
One promising way to interrupt these cycles is therapeutic fasting. Fasting means voluntarily avoiding food for a period of time, under medical guidance.
In recent years, fasting has gained attention for its effects on metabolism, weight, and blood sugar control. Researchers have now found that fasting can also lead to significant drops in high blood pressure.
A key reason fasting may work lies in how it affects insulin. Insulin is a hormone released when we eat, especially foods high in sugar or refined carbohydrates. While insulin is essential for controlling blood sugar, high insulin levels are closely linked to high blood pressure.
Constant eating and frequent snacking can keep insulin levels elevated throughout the day, which may contribute to long-term blood pressure problems.
During fasting, insulin levels fall sharply because no food is entering the body. This gives the body a chance to reset its metabolic balance. By lowering insulin and giving the body a break from constant digestion, fasting may disrupt the harmful cycles that keep blood pressure high.
Recent studies have shown impressive results using a structured approach. In these programs, patients follow a period of water-only fasting under supervision.
This is then followed by a carefully designed maintenance diet that is low in fat, low in salt, and based on whole, plant-based foods. Many patients experience large drops in blood pressure, often reaching healthy levels without the use of medication.
Even more encouraging is that these improvements are not short-lived. Patients who stick to the follow-up diet tend to maintain their lower blood pressure over time.
This suggests that fasting, when paired with a healthy and sustainable eating pattern, could offer a long-term solution rather than a temporary fix. Some researchers even describe this approach as a potential natural cure for high blood pressure.
Not everyone can safely complete a full fast, and researchers recognize this limitation. For people who cannot avoid food entirely, an alternative approach may be a protein-sparing modified fast. In this method, people consume small amounts of protein while avoiding most calories.
This helps protect muscle mass while still lowering insulin levels and triggering many of the same metabolic benefits as complete fasting. If proven effective, this approach could be easier to use in outpatient settings and accessible to a wider group of patients.
The potential benefits of fasting may reach far beyond blood pressure control. Researchers believe that breaking harmful metabolic cycles could also help manage other chronic conditions. These include type 2 diabetes, where insulin resistance plays a central role, and autoimmune diseases, which may be influenced by metabolic stress and inflammation.
The researchers suggest a powerful idea: if a disease can be prevented by a certain diet but not reversed once it develops, fasting followed by that same diet may help reverse the condition. In this way, fasting acts as a reset button, allowing the body to respond more effectively to healthy eating afterward.
While more large-scale studies are needed to confirm safety and long-term results, this research highlights the growing potential of fasting as a natural, drug-free approach to chronic disease management.
Combined with a nutritious and sustainable diet, fasting could offer new hope to people seeking lasting control over high blood pressure and other metabolic disorders.
