In our natural state we actually have MORE water inside our cells than outside our cells (subcutaneous water). It is when you screw with things that you start getting problems. People seem to have this notion that if they cut water, they will lose all their subcutaneous water. There are a few problems with this: 1) You won't just lose water from the subcutaneous area, you will also lose it out of the muscle tissue, and you will most likely lose MORE from the muscle than from the subcutaneous layer as the body will attempt to maintain the water balance between the inside & outside of the cell. 2) You will flatten yourself out big time. The only reason a carb load works is because the increased glycogen causes your cells to store more water. All you have really done is flatten yourself out, you haven't changed the ratio of intracellular/extracellular water at all.
What you have to remember is that even if you are holding water under the skin, cutting water is not the best way to get rid of it. If you are holding water under the skin & you cut it then you are just going to increase aldosterone even more and reabsorb more water from the nephrons into the interstitial space. When you cut water or take a diuretic you will not be able to control where you take it from? it is going to come out of muscle and out of the subcutaneous tissue; the problem is it's going to come out in the same ratio contained by the two areas.
There is a ratio of intracellular to extra cellular water. When you cut water will you lose some extracellular water? sure, but it is going to maintain that same gradient. IT HAS TO. You see, if you could drastically change the volume that one held without affecting the other, then you would cause massive movement of solutes also as one area losing water would drastically increase the concentration of solutes in that area. This could affect all kinds of things like electrochemical gradients and things CRUCIAL to proper cell function. Therefore, to maintain this gradient in the proper ratio water will leave the intracellular space into the extracellular space to equilibrate the concentration gradients.
Since most people who cut water also cut sodium at the same time, that means your levels of ADH/aldosterone will be VERY VERY high (can increase several fold in a matter of 48 hours of depleted sodium) that means that you will be reabsorbing sodium/water. Only now since your sodium is low, you do not have the pressure in the vascular system to maintain the reabsorbed water IN the vascular system and it will leak into the interstitial space.
What is more, the glucose transporter, SLGT-1, in the small intestine is a sodium dependant transport and low sodium intake has been shown repeatedly to DECREASE THE RATE OF GLUCOSE UPTAKE. this is important because all these guys are typically carb loading big time at the same time they deplete water & sodium in the misguided effort to 'fill out'. So now you are getting less glucose into the enterocyte and less into circulation. So you aren't getting the muscle the glucose it needs. What is more, now you have all that extra glucose sitting in the small intestine acting as a solute & drawing water into the small intestine. Not good to have a bunch of fluid in the gut.
Εδώ έρχεται η αρχή Le Chatieler - Van't Hoff , το νερό στα νεφρά, κάτω από το δέρμα κ στους μύες βρίσκονται σε χημική ισορροπία, είτε παίρνεις διουριτικά είτε σταματάς να πίνεις νερό αναγκάζεις την ισορροπία να μετακινηθεί προς εκείνη την κατεύθυνση στην οποία η έλλειψη νερού θα αντισταθμιστεί δλδ ή θα χάσεις νερό και από τους μύες ή/κ (ανάλογα την περίπτωση) θα έχεις περισσότερη κατακράτηση. οοοοppsss!
(έχω βάλει κ κάποια παραπάνω λογάκια απτο αγγλικό κείμονο, έτσι for the fun of it, λέει ωραία πραγματάκια)
Να το πούμε χωρίς να χαιδεύουμε ο ένας τα αφτιά του άλλου, αν νομίζεις ότι κρατάς νερά, απλά είτε χρειάζεσαι δίαιτα είτε χρειάζεσαι δίαιτα.
Αυτό που λένε να δώσεις χρόνο από την διακοπή της κρεατίνης, έχω τις αμφιβολίες μου αν αυξάνεται τόσο το νερό κάτω από το δέρμα λόγω της ισορροπίας κ δε φταίει η carbloading διατροφή, μια κ όσοι κάνουν γράμμωση πάλι χρησιμοποιούν κρεατίνη, μια κ γιαυτό χρησιμοποιείται η κρεατίνη για περίσια ενέργειας, ουσιαστικά αυτό είναι.
