Is It Possible To Lose 50 Pounds In 3 Months On The Hcg Diet?

I am going to the maid of honor in a wedding for my best friend in 3 months and I would love to lose 50 pounds for the wedding. I have been exercising and eating healthy for the past 2 months and I have only lost 10 pounds. Do you think 50 pounds in 3 pounds is reasonable on the HCG diet?
