frustrated

Hi

I have been on this juice fast for 3 days now. I feel bloated, constipated and have not lost any weight, and have had no bowel movements so far. Instead I have gained 3 lbs. I drink 2: 16 oz of juice daily. Juice 1: kale, cucumber, celery, green apple and ginger. Juice 2: Carrots, beets, ginger and red apple. I drink water and I walk every day. I need to lose 40 lbs. I have gained lots of weight after I had my last child 4 years ago. My tummy still looks like i'm pregnant and I suffered from food addiction. I am really trying to stick to this, but feel like giving up and eat again. What went wrong??
