Yes, easily. First thing you got to do is boost that metabolic rate up to burn fat quickly, here's what you should do:
Drink nothing but water for the three weeks.
Cut out all junk, grease, fried and fatty foods.
Increase vegetable and fruit intake (aim for around 7 of both daily) get a lot of greens in there like beans, spinach, broccoli, and kale.
Eat whole grains, especially brans and oats. They are much better than white bread.
If you're a meat eater, eat white grilled/baked meats like fish, and chicken (salmon and chicken breast is best)
Exercise, you got to sweat out that excess weight. Run, jog, bike, swim............just build up a nice sweat, and give it your all during a workout.
Strength training, incoroporate strength exercise into your workout regiment. Weights, pushups, weighted squats are great...........they are a total body workout.
Adequate rest is important as well for your body to function at its best.
5-6 smaller meals a day is better as oppposed to 3 larger ones, this will speed up digestion and your metabolic rate. Eat right, drink water, and exercise..........if you can do that you can easily lose 5lbs a week.
Stay focused and disciplined, and you will surely reach your goal.
All the best
