Below is a copy and paste from DX...very knowledgeable man.  It might help.  He had said after WLS it is like decending stairs...
 

Still staying on-track calorie-wise? And the scale shows you stopping? Or Even Gaining?!?!?--Re-Post Unsolicited advice/info… -------------------------------------- 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. Fear not, many people who are now enjoying life at a normal BMI Once had a few weeks or so of thinking- "...my weight loss has been awfully slow, has it stopped..."? Hope this helps some. You are doing Great! Keep it Up! Best Wishes- Dx

But does fat taste different post op??

Sorry, can't help you.  You may want to try the Exercise and Fitness Forum here at OH...

Guilty!!  Sorry I haven't been around...I do look and try to respond as needed.  I have a crazy schedule now, so I have to prioritize my time.  I work a few nights and have an hour+ commute at other sites (and I'm getting older).  If it's an important post I am on it...lighter stuff I just pass it bye.

A couple things are different from when I had my surgery 6+ years ago.  When I had mine it was very new and strange thing.  Yeah, you had stomach stapling over the years, but gastric bypass was a new concept.  I remember when my dad had heart bypass at Stanford Hospital in the late 70's.  He was about the 10th person in the nation to have it..."You're going to take a vein from your leg and put it on your heart"!!  Oh and you'll stop the heart for an hour or two and then restart it...!!!  Are you nuts!!  Wacko!!  Now we think nothing of it.  I think the same could be said about gastric bypass.  Walk into a large meeting of people (over 100) and I'm sure 3 or 4 have had it done.  When I first had it done major issues were popping up that the surgeons didn't expect or know...It was a trial and error and your life depended on it.  I would go to support groups or be online here at OH and see new issues come up daily and I mean daily.  My surgeon walked into the local support group and said 2 RNY patients had come down with Beri Beri!!  We were freaking out (vitamin B-1 deficency...That is why you take your B complex).  Now you can go to friends, family, neighbors, and coworkers to get information about these surgeries.  Just trying to share how it has changed.  We are still here.  And every few weeks or months I'll post my siren song on the Main, VSG, and RNY boards...An invite to come on over with the link.  We make this board what it is...
 

Hey Bill thanks for the post...This is why this forum is so cool, we can relate and throw out ideas.  I'm in the same boat...RNY, heart bypass, 1 stent, aspirin, and Plavix.  So here are my thoughts and what I went through.  After my second heart attack I was put on Plavix (post RNY).  When I started taking it I was doubled over in pain.  I pressed through and keep taking it.  When I bleed from a cut, if it takes over 2 minutes to stop bleeding, I will do a 1/2 of Plavix the next dose or drop the 81mg of aspirin for that day.  This is what I think...Just me.  It could be the Plavix and it could be in your remnant stomach. The problem is they want to control it, if they can, with medication...since it would take doing exploritory surgery to try and find the problem. I take both with no problems...Just me.  I will also take an Advil (one), every time I pull or strain a muscle (NSAID).  When I do I can feel the irritation in my old stomach. Taking the Advil is the only time I can sense my old stomach.  Just saying, Plavix can too cause bleading...Brian

Don't want to get into the politics of this evening...The elections.  But I'd like to throw out my situation and see what you think would be the best thing for me and my wife to do.  I am 57 and my wife is 55.  Both of us have preexisting conditions.  I have my own policy which costs about $1,750. a month.  My group is old farmers between 55-64 years of age.  My wife's policy is for her and my daughter.  It's about $625. every month.  I can't get on her policy and she can't (who would) get on mine.  I also have one of those limited coverage plans at work that has a limit of $50,000. per year.  You go into the hospital for a week and you have used it up!!

So some of my questions are; since the Republicans control the House will they fund Obamacare?  Is it going forward...Or will it be stopped flat in its tracks??  These 2 policies are eating us alive.  I'm trying to protect our assets and retirement.  Instead of having a clearer picture of how to plan for my health protection it becomes muddier.  Your thoughts??

Two words come to mind...body frame.  I was a high school football player (lineman).  Of course I thought I was a large frame.  My nutritionist said I was a medium frame...I laughed at him.  Sure enough, he was right.  You could be a small frame (muscle and bone structure).  If I were you I would work toward 156 and see how you look a that time.  If you are gaining muscle mass from exercise or lifting, readjust as needed.  At 156 you should see how much excess skin you have (the younger the man and the lighter the weight to start off with, the lesser the amount of skin).  As long as you do not drop below 2% body fat (excluding skin) you should be OK.
