Good question... I dunno what is the answer to that question. I'll do some investigation and get back to you if I got an useful answer. You should email the people at Medifast as they probably know..
It just happens. I think our bodies just need to adjust once in a while, especially at the beginning. We kinda shock our body by all of sudden drastically changing what we're feeding it...
YUP, I think due to all the water loss in the 1st 2 weeks, we see great weight loss at fisrt, then we get to the business of losing "real" weight....and reality kicks in...but the program works, dig your heels in and you'll see great results.......
Thanks you guys, I guess I just needed reassurance. My brain is saying it should be simple math calories in/calories out you know - and I see that on the online tracker I use. So I'm like, come on - it's simple math!.
But I guess I know better! I just look at other people's progress they've posted and I see that it does vary from week to week. I guess we are putting our metabolisms through an awful lot, lol..
Wishing everyone success! I do love this diet though.
And I am still gonna hope for my mini-goal I have listed (169 by April 21). Although with this week 3 thrown in, not sure it will happen!..
I think maroops has stated it pretty succinctly. There are a lot of factors coming into play. Remember that 1 pound = 3500 calories; doing the math suggests that the first week's change in the scale is unlikely to be all fat loss. What is happening is that in that first week the body's glycogen stores are being used up. The body stores glycogen in muscle and uses it for energy. When we limit carbs we are not replenishing the glycogen, and so the body turns to fat (so long as there is enough protein to protect muscle) and begins burning it for fuel..
Glycogen bonds with water, it's either three or four molecules of water to one of glycogen, I forget (I am not a doctor nor do I play one on t.v.). Using up the glycogen also uses up or frees the water, and this contributes to the first week's big loss..
After that first week we have used up glycogen stores (are in ketosis) and now we are burning real fat (probably some real fat is also lost the first week). Going back to the math, weight loss will of course slow down because we have to get rid of 3500 calories to get rid of one pound. But it's not a straight linear relationship the way you'd think it should be. Many other factors are contributing to the number on the scale, including what time of day it is, what time of month it is (for women), how much you have eaten/drunk/eliminated before you get on the scale, whether you've had a good night's sleep (being short on sleep has a correlation to weight gain/lack of loss), stress (cortisol), etc. And as cllycan notes, the body is adjusting to a bit of a shock in the way it is receiving it's fuel..
Hang in there. This too shall pass..
Thank you for the information MelindaAnn. I too was a bit discouraged after losing only a pound the second week, first week was pretty successful. Your explaination helps put it all into perspective...
This is my first day on Medifast and all of this information has been very helpful. Thank you for letting me know what to expect from week 3!!!..
Yes, MelindaAnn, thank you for the technical explanation. I always need to know WHY, and I can keep that in mind as I move ahead. I did not know that about the glycogen being eliminated at the start..
Maybe even tomorrow's official weigh in will be different than this mornings! Ya never know, lol. Good luck to all! (although it has nothing to do with luck!)..
Plus you dont have much to lose and your losses will be kinda low to nothing each week..
