complex theme here.
For not having water retention you have to consider many factors:
aas and consequently estrogen;
carbohydrates. every 1gr of carb retains 3-3.5 grams of water;
but above all the intake of water, sodium, potassium and aldosterone must be balanced.
When salt intake is reduced, a series of dry-looking enemies emerge.
The salt contains sodium and to a lesser extent potassium in the form of potassium iodide. When salt/sodium is reduced or eliminated from the diet, the result is a greater release of Aldosterone.
This causes the body to excrete more potassium and retain more sodium/water. The subsequent water retention gives the athlete a swollen appearance due to the imbalance between the electrolytes. The lower salt intake negatively affects the very important sodium-potassium pump.
This is the mechanism used by the body to transport many nutrients into cells such as those of all muscle fibers.
Subcutaneous water control depends on the control of the hormone Aldosterone. Obviously estrogen control is part of this hormonal cascade of action/reaction factors.
The thing that most interests us is salt and water control, so the key element is Aldosterone.
For diuretics:
10 days or so out start an Aldosterone blocker like Spirinolactone. Start at 25 mgs and titrateup 25 mgs a day to 100.
Introduce a Thiazide at 25 mgs and titrate up. Hit 100 mgs of each on Thursday, 2 days out. Hold 100/100 on Friday.
Do not touch any loop diuretics like lasix until Friday night before the show. Crush up a 20 mg lasix tab, wet your finger and take in a little bit of lasix.
Be very conservative with the lasix, adjust according to how you look.
Do not do more than 20 mgs between night and pre judging.
Don't cut water until Friday 6 PM.
