NO, you can not lose 25 pounds in 2 wks. You can harm your health and possibly your life. To attempt it would impact your heart, liver, kidneys, etc.
Try a weight loss jump start plan. They usually have eating plans, cardio work and strength training/sculpting. They involve nutritionists, certified trainers and doctors; safe and effective in the least amount of time. You may not need to lose weight so much as tighten, tone and sculpt. These programs are online at the following: About, Prevention and Women's Health.
