high blood pressure by breaking harmful cycles in the body’s metabolism.
It’s well known that eating too much salt can raise blood pressure. But cutting back on salt doesn’t always bring blood pressure down very much. This means salt might be working with other parts of a modern diet to keep blood pressure high, even when salt is reduced.
Fasting, which means not eating for a certain period of time, has been shown to reduce high blood pressure. One reason is that fasting lowers insulin levels in the body. Insulin is a hormone that helps control blood sugar, but it also affects blood pressure. When insulin goes down, it may help the body reset and lower blood pressure.
Studies have found that doing a water-only fast—where people only drink water—and then switching to a low-fat, low-salt, whole-food vegan diet can greatly reduce blood pressure. Even more exciting, people who stick with the diet after fasting often keep their blood pressure at healthy levels without needing medication.
This suggests that fasting, along with a healthy diet, could offer a long-term, natural way to control or even reverse high blood pressure.
For people who can’t do a full fast, there may be another option. A protein-sparing modified fast allows for small amounts of protein to prevent muscle loss. This type of fasting might offer many of the same benefits and could be easier to manage outside of a hospital.
The possible benefits of fasting don’t stop with blood pressure. Researchers believe fasting may also help treat other conditions like type 2 diabetes and autoimmune diseases. These are also tied to problems in the body’s metabolism, and fasting might help break the cycles that cause them.
For example, if a special diet can prevent a disease but not reverse it, fasting first and then starting the diet might be more effective. This combined approach could offer better results than diet alone.
The findings show that therapeutic fasting could be a powerful, drug-free way to manage chronic health problems. Although more research is needed to make sure it’s safe and works for more people, fasting combined with a healthy, long-term diet may bring real hope for people with high blood pressure and other health issues.
