Water Fasting at already Low Weight

Hello, I would like to trying healing torn joint tissue (knee cartilage, ligaments) and eczema on my nose with water fasting, potentially followed by a Liver Flush and raw food diet. I have had both problems for about a year and they have worsened over time.

However I am a bit concerned about the effects of fasting at a low body weight (5'6", 100 pounds; not anorexic - I haven't exercised in a year due to my injury, eat a box of cookies every week, and do not restrict food; this is just me). At the same time I think a complete inner detox of the sorts mentioned is necessary since my internal organs have taken a beating over the years from so many courses of Antibiotics and medications. My body is having trouble healing itself.

Does anyone have thoughts on how to handle Water Fasting or flushes and a raw food diet at a low BMI? Maybe if I cycled Water Fasts and raw food for short, 1 week periods, over the course of several months I can get the benefits of detoxing without losing a lot of weight? Tweet
