Found what I copy and pasted on FACEBOOK... here is that info:
Copy and Pasted - info from Baka in a thread on BTV - excellent discription of the process of those WTF moments our bodies do.
***Pull back from your ‘daily’ charting, and look at a weekly or even monthly. There are up and down spikes each day, But if you ‘graph’ the highest to the lowest, I’d bet there is still A downward slope over the course of the month.
There’s an 8 to 10lb. volume of "wiggle room" due to water alone. And it comes into play a lot. This has to do with our bodies using glycogen for short term energy storage. Glycogen is not very soluble, But it is stored in our muscles for quick energy – One pound of glycogen requires 4 lbs of water to keep it soluble, And the average glycogen storage capacity is about 2 lbs.
So, when you are not getting in enough food, (Like when you drop down to your calorie intake) Your body turns first to stored glycogen, Which is easy to break down for energy. And when you use up 2 lbs of glycogen, You also lose 8 lbs of water that was used to store it Voila -- the "easy" 10 lbs that most people lose in the first week of any diet.
As you stay in caloric deficit, however, Your body starts to ‘realize’ that this is not a short term problem.
You start mobilizing fat from your adipose tissue And burning fat for energy. But your body also ‘realizes’---- (by way of your liver releasing hormones signaling low Cal intake) ---That fat can't be used for short bursts of energy – Like, to outrun a saber-tooth tiger. So, it starts converting some of the fat into glycogen, And rebuilding the glycogen stores.
And as it puts back the 2 lbs of glycogen into the muscle, 8 lbs of water has to be stored with it to keep it soluble. So, even though you might still be LOSING energy content to your body, (Thus showing negative Calorie load overall) Your weight will not go down or you might even GAIN for a while As you retain water to dissolve the glycogen that is being reformed and stored. Yes? The whole ‘weight-loss’ process is not a straight "Slide" down the scale. More like "Stair-Steps," (Down then forward, then down, then forward, etc... As your body cycles fat out of "deep storage" and through the Liver Into the muscles as Glycogen.
The muscles and Liver can hold about a 3 weeks supply. This is why many people find that their "Stall" or "Plateau" Breaks when adding a bit of exercise And upping their water intake, or in the case of an "extreme exerciser," The total Calorie or Protein Intake, To signal the liver to let go of more Glycogen.
Hope this helps some. You are doing Great! Keep it Up***
