Gravitational Resistance and Diet (GRAD) System is developed by Dr. Biswaroop Roy Chowdhury for reversing Chronic Kidney Disease (CKD.) Thousands of CKD patients are benefiting by this treatment protocol and several hospitals have already adopted the GRAD System. Shridhar University in collaboration with Dayanand Ayurvedic College conducted an observational study to find the effectiveness of GRAD System. The study concluded that among the patients who adopted the GRAD system completely 75% could free themselves of dialysis and 89% could free themselves of full or partial dependence on drugs.

Hence, GRAD System is the only known scientifically validated method to reverse Chronic Kidney Disease.
