Sugar is deadly (causes obesity, type 2 diabetes, metabolic syndromes, cancer, etc) many would say and they are right. Our body can only safely metabolize 6 teaspoon of sugar a day, and the average Malaysian and Thai consumption of sugar per day is 26 teaspoons!
A juice cleanse means going on a juice fast for a duration of time. The theory behind it is basically giving your body a break from solids, and letting your body focus on healing itself - essentially means getting rid of toxins from your body and giving it a reboot! Hence, for those who are going on a water fast, or master cleanse, the detox works just the same. It’s the act of “fasting” or abstaining from solids that’s doing the work of cleansing, not so much the juices!
However, juice cleanse comes highly recommended because it becomes double-duty - the act of fasting with the addition of nourishment from raw, pressed juices. So with juice cleansing, you get the benefits of fasting and at the same time feeding your body with vital nutrients and vitamins - your cells are being repaired and fed at the same time!
