I love the idea of healthy fasts, and will be incorporating the idea of fasting into a healthy diet plan I am working on. Since I am also serving as the guinea pig for this diet and the fasting, I have to say that I can hardly imagine a diet that stretches out to 30 days or more. Based on my own experience, I would call 8 days Herculean! Of course my fast was a two day one that had grapes and grapeseeds the first day and watermelon the second. That is a combination fast and cleanse, let me tell you! But it dropped 7 pounds, left me feeling invigorated and also with a bit smaller stomach capacity. I am thinking that one day a week of fasting on the grapes or watermelon or juices/juiced vegetables and smaller healthy meals interspersed with healthy snacks and healthy supplements is a good plan for reaching and maintainiing a healthy weight and a healthy body too.
