Anywhere from 30-60 pounds. Depends on how hard you work, and if you can lose 1 pound a week or 2. Don't try to go over that, tho, because you're body will have a hard time keeping up if you lose more than 2 or 3 pounds a week (usually, tho, people end up losing 5-10 pounds their first week due to water weight, so that's ok, just don't make it a habit!). Good luck.
