Your body is doing lots of work besides... shedding pounds!!
During my long fast last summer I went for a week straight without losing a thing during a kidney crisis. Obviously my body was working hard on detoxing my kidneys. When the crisis had ended, I started to lose again.
The Master-Cleanse should not be considered a "weight loss program", but rather an internal cleanse. And everyone should definitely be aware that any and all weight you lose while fasting will come back with a vengeance if you return to unhealthy habits! Start now to plan your post-fast diet and exercise routine!
Have faith... your body is getting a much needed rest from the constant burden of digestion and is busily cleansing, detoxing and healing.
