Autophagy, a process in cells, may protect against diseases like cancer, Alzheimer's, and heart disease. Water fasting promotes autophagy, extending life span, but more research is needed.
May help lower blood pressure
Long, medically supervised water fasts may help people with high blood pressure lower their blood pressure, improve cholesterol levels, and reduce inflammation, though more research is needed.
May improve insulin and leptin sensitivity
Water fasting can increase sensitivity to insulin and leptin hormones, enhancing their effectiveness in metabolism, reducing blood sugar levels, and reducing obesity risk.
May lower the risk of several chronic diseases
Water fasting may reduce chronic disease risk and promote autophagy, but more research is needed from animal or short-term studies before recommending it.
