Cutting 17lbs in 2 weeks is easy money...If you prepped your body for the 17lb cut several weeks prior to starting your weight loss. If you've been eating Doritos and skipping workouts for the last few months I definitely would not recommend trying to lose 17lbs in 2 weeks.
If you haven't prepped for the cut then most of the weight you lose is going to be water, as when you restrict your calorie intake, your body is going to kick into survival mode and try to hang onto as much weight as it can at first.
You need to lose 17lbs, a gallon weights roughly 8.5 lbs. Do you think you can drop 2 gallons of fluid from your body in 2 weeks and still healthy enough to compete?
