If you love to eat & are trying to lose weight this shake is not only delicious but, also very filling. I substitute it for snacks & also sometimes meals when I don't have time to sit down & eat. Attain shakes have a patent-pending Craveblocker that curbs your appetite. Attain shakes come in chocolate, strawberry, & vanilla flavors. I haven't tried the others yet but, when I do I'll update this review & let you all know. There are ten servings per package. All you have to do is mix one scoop with 8 ounces of water or milk. (I choose milk because it tastes better to me.) It tastes just like a yummy chocolate smoothy & doesn't leave you hungry. Melaleuca sells cups that have the premeasured line & just pour your desired liquid to then add the powder & shake. It says to drink immediately but I like to let mine sit & calm down for a few minutes so it is not so frothy at the top. If you like froth though drink it right away. Check with you physician first if this is right for you. If it is, your in for a treat!
