Keep sodium high while dieting, that way when you cut sodium out, its a more dramatic cut.
drink 2 gallons to 3 gallons of water daily during diet.
2 days out, cut water to 1 liter, cut sodium in half.
day before show, zero water, cut sodium to ZERO, eat nothing but sweet potato's day before contest.
you take in several gallons of water daily for 9 or 10 weeks, when you cut water out, the body is tricked, it will think its taking in the same amount of water for 3 days even though you cut it. so the body will try to expel the same amount, along with sodium at zero, the body flushes all the water out of you.
Ta, da!
