Arbonne redone the shake formula a while back,I think they taste much better now in both ready mix and powder, I like to blend mine with a frozen banana at home and use the ready Mix when traveling. I have lost a 105 pounds so far with them since march. I also cut some other bad habits such as soft drinks and fast food. I would like to lose a few more pounds and plan to start exercising soon..I have been on other programs, Herbalife, phentermine, etc ..but I think Arbonne has been the easiest and healthiest for me......
