Has anyone used this or know of it or if it works I picked it up at the store today for about $20 it says add 1 scoop with water and drink it in the morning and if you want another in the afternoon and yes it with a low calorie diet of 1350 calories a day and with exercise and that studies show overweight women can loose about 25 pounds in 13 weeks I wasn't sure how well this works and wondered if anyone uses it or uses anything else that works better
