That depends on your current weight, but realistically, that's not a safe amount of weight to lose. An average, safe weight loss per week is 1-2 pounds, depending on your size. If you have more than 100 pounds to lose, it might be possible, if unlikely, but if you have less than that, it's going to be dangerous to even try.
Skip fast weight loss. Aim for slow and steady, and take care of your body. It took time to put the weight on, it will take time to take it off.
