I tried the above hydration / dehydration cycle with my father in June 2014. At that time he was 80 year old. He suffered from Sepsis, Multiple organ failure, Chronic Kidney Disease Stage 5, High Blood Pressure, Severe Constipation, Prostate issues, Epilepsy and Gangrene. The doctors had opined that it is impossible that he can survive even if taken to the best of hospitals in the world.
This seems hard to do, but really it’s not if you know one secret: Replace snacking with something far more satisfying — fat. That’s right, the government is wrong to recommend a low fat diet. Fat is what makes you feel full until your next meal. Take away the fat, take away the full. Don’t go to an extreme, but do lean strongly toward a high-fat low-carb diet.
