Hi Gilda,

Of the 7-8 lbs. I lost in the 72 hours, I would say 3-4 may be water. Since you consume little or no sodium juicing, there is little water retention by the body by the third day or so. As far as the sauna is concerned, the effect on the heart is similar to a cardio workout. After 20-30 minutes, my heart is beating between 120-135 per minutes which is the range I maintain when doing cardio on the eliptical trainer. The added benefits of sweating helps in the detox process by elimation of toxins through the pores. I woke up this morning and weighed 206. That's 9 lbs. since Monday morning. Thanks for the encouragement. I wish you best if you are going to juice fast. It has been a great experience for me.
