Rather than cut 8lbs of fat, why not cut 8lbs of water? What's the weight class you're going for, and are the weigh ins 2hrs or 24hrs? Keep your calories where they are, maybe clean up the diet to get nice and close, if you get to within seven pounds one week out, you're golden. Here's why:
One week out, cut out all carbs until weigh ins. Drink two gallons of water a day. Salt all your food in the beginning of the week, for at least the first couple days. Drop salt 2 days out from weigh ins, drop ALL water 18hrs from weigh ins. You're allowed ONE SIP each time you piss. Wake up early when you go to weigh in and if you're still over weight, hit the sauna for 10min on, 2min off until you make weight.
After you make weight, drink 2 gallons of half Gatorade, half water throughout the day, eat all the carbs and salt you can fit in your piehole every 2hrs, and do a light band workout after a couple meals. Your goal after weigh ins is to be heavier than you were at the beginning of the cut week. 10lbs over your weight class would be ideal. Then get a good night's sleep and crush some PRs.
