Scientists at Pantox Laboratories believe that fasting might do more than just help people lose weight—it could actually help lower high blood pressure naturally.
Their new idea suggests that taking breaks from eating can stop the body from falling into harmful metabolic patterns that keep blood pressure high.
Many people know that eating too much salt can raise blood pressure. However, cutting back on salt alone often doesn’t make a big difference.
This has led scientists to think that salt might work together with other parts of the modern diet, such as processed foods and high sugar intake, to create a kind of self-sustaining loop. This loop keeps blood pressure high even when someone starts eating less salt.
Fasting, which means going without food for a period of time, has been shown to lower blood pressure in a natural way. One reason for this effect is that fasting lowers the body’s insulin levels.
Insulin is a hormone that helps control blood sugar but also plays a role in blood pressure. When insulin levels drop, the body’s overall metabolism seems to reset, helping to break the cycle that keeps blood pressure high.
In recent years, several studies have looked closely at this idea. They found that when people follow a plan that begins with water-only fasting and then move to a diet based on whole, plant foods that are low in salt and fat, their blood pressure drops significantly—sometimes to normal levels—without needing medication.
Even more importantly, the improvement often lasts. People who stick to the healthy, low-salt vegan diet after fasting usually maintain their lower blood pressure for months or even years.
This discovery has made scientists wonder whether fasting could be a kind of natural reset button for the body. Instead of treating high blood pressure only with drugs, fasting might help fix the root of the problem by restoring the body’s balance.
For people who can’t do a complete fast, a modified version may also help. In what’s called a protein-sparing modified fast, people eat a small amount of protein to protect their muscles while still getting the metabolic benefits of fasting.
If this easier version works, it could make fasting safer and more practical for more people. Doctors could even use it in outpatient settings, where patients don’t have to stay in hospitals. That would make fasting a more accessible and affordable option for people struggling with high blood pressure.
But the benefits of fasting might not stop there. Researchers also believe it could help with other conditions linked to metabolism, such as type 2 diabetes and autoimmune diseases. Fasting might help break harmful cycles in the body that keep these diseases active.
When followed by a long-term, healthy eating plan, fasting could help prevent or even reverse some of the damage these conditions cause.
This research shows that fasting isn’t just a trend—it may be one of the simplest and most natural tools we have to restore health. Although more studies are needed to confirm how safe and effective these methods are for different people, the early findings are exciting.
Combining short periods of fasting with a nutritious, plant-based diet could offer a lasting, drug-free way to control high blood pressure and improve overall metabolic health.
