[muzza]

hi guys ,just wondering ive read on these forums a few times how most of the first week or so of weight loss would be water,but im confused eg; yesterday i was so thirsty all day i drank about 5 litres of water [4th day of induction dry mouth ]i usually drink at least 3 litres,so how could any weight u lose initally be water when if like me u drink 5 kgs of water ? lol cheers for any ideas

from an article entitled "Why the Scales Lie":

"So... what gives? Initially, the body jettisons the water attached to the glycogen stores that we diligently deplete to get into ketosis...this accounts for about 3-5 pounds of water. In addition, muscle stores of glycogen are not being replaced when used...which will account for the rest. All in all...MAYBE 1/2 pound of fat was metabolized during the first week... and MAYBE 1/2 pound of fat was metabolized the 2nd week. Of that 10 initial pounds, only 1 pound was fat and 9 pounds water...

The body senses this lack and sirens start shrieking: Warning! Warning! Losing water... new thing...got to get back to the status quo! Brain tells body to produce and release that vasopressin anti-diuretic hormone....more water is retained, and no weight loss noticed. Fat loss is still occurring, MAYBE even 2 pounds per week, because ketosis is firmly established and appetite suppression is in effect...but water retention is hiding that continuing fat loss. The body is preventing dehydration with this mechanism, and that's a good thing."

Hope that helps.
