You are 100% right it's scientifically proven ....please click on the link incase any one have any doubts

For years, studies of obesity have found that soon after fat people lost weight, their metabolism slowed and they experienced hormonal changes that increased their appetites. Scientists hypothesized that these biological changes could explain why most obese dieters quickly gained back much of what they had so painfully lost.

But now a group of Australian researchers have taken those investigations a step further to see if the changes persist over a longer time frame. They recruited healthy people who were either overweight or obese and put them on a highly restricted diet that led them to lose at least 10 percent of their body weight. They then kept them on a diet to maintain that weight loss. A year later, the researchers found that the participants’ metabolism and hormone levels had not returned to the levels before the study started.

The study, being published Thursday in The New England Journal of Medicine, is small and far from perfect, but confirms their convictions about why it is so hard to lose weight and keep it off, say obesity researchers who were not involved the study.

They cautioned that the study had only 50 subjects, and 16 of them quit or did not lose the required 10 percent of body weight. And while the hormones studied have a logical connection with weight gain, the researchers did not show that the hormones were causing the subjects to gain back their weight.

Nonetheless, said Dr. Rudolph Leibel, an obesity researcher at Columbia, while it is no surprise that hormone levels changed shortly after the participants lost weight, “what is impressive is that these changes don’t go away.”

Dr. Stephen Bloom, an obesity researcher at Hammersmith Hospital in London, said the study needed to be repeated under more rigorous conditions, but added, “It is showing something I believe in deeply — it is very hard to lose weight.” And the reason, he said, is that “your hormones work against you.”

In the study, Joseph Proietto and his colleagues at the University of Melbourne recruited people who weighed an average of 209 pounds. At the start of the study, his team measured the participants’ hormone levels and assessed their hunger and appetites after they ate a boiled egg, toast, margarine, orange juice and crackers for Breakfast. The dieters then spent 10 weeks on a very low calorie regimen of 500 to 550 calories a day intended to makes them lose 10 percent of their body weight. In fact, their weight loss averaged 14 percent, or 29 pounds. As expected, their hormone levels changed in a way that increased their appetites, and indeed they were hungrier than when they started the study.

They were then given diets intended to maintain their weight loss. A year after the subjects had lost the weight, the researchers repeated their measurements. The subjects were gaining the weight back despite the maintenance diet — on average, gaining back half of what they had lost — and the hormone levels offered a possible explanation.

One hormone, leptin, which tells the brain how much body fat is present, fell by two-thirds immediately after the subjects lost weight. When leptin falls, appetite increases and metabolism slows. A year after the weight loss diet, leptin levels were still one-third lower than they were at the start of the study, and leptin levels increased as subjects regained their weight.

Other hormones that stimulate hunger, in particular ghrelin, whose levels increased, and peptide YY, whose levels decreased, were also changed a year later in a way that made the subjects’ appetites stronger than at the start of the study.

The results show, once again, Dr. Leibel said, that losing weight “is not a neutral event,” and that it is no accident that more than 90 percent of people who lose a lot of weight gain it back. “You are putting your body into a circumstance it will resist,” he said. “You are, in a sense, more metabolically normal when you are at a higher body weight.”

A solution might be to restore hormones to normal levels by giving drugs after dieters lose weight. But it is also possible, said Dr. Jules Hirsch of Rockefeller University, that researchers just do not know enough about obesity to prescribe solutions.

One thing is clear, he said: “A vast effort to persuade the public to change its habits just hasn’t prevented or cured obesity.”

“We need more knowledge,” Dr. Hirsch said. “Condemning the public for their uncontrollable hedonism and the food industry for its inequities just doesn’t seem to be turning the tide.”

Guys being obese is a disease its a constant struggle my insurance paid 100 % for the surgery cause they know its a proven tool I think its more of a perception of people to think that we can lose weight on our own I wish it was that simple. I used to cry when I was a kid my cousins who r super skinny used to eat so much and I used to be chubby while eating much less and much healthier food. So this disease is as serious as heart disease after only 9 days of surgery my doctor told me to immediately stop using insulin, high BP medicine and metmorphine First time in 6 years I don't have to inject in my stomach anymore twice a day to me it's the best thing any obese person can do.

I don't think comparing a WLS patient to a cardiac patient is really a good comparison. Being overweight is something that can be reversed' date=' whereas heart blockages & other damage to the heart is most often irreversible. One surgery is a medical necessity, whereas the thre is elective.

The reason for most of our surgeries is because most of us lack the willpower to make a lasting lifestyle change without it. And, yes, WLS is the "easy" way out. That doesn't mean that it isn't without it's challenges, but for us, it is obviously easier than diet & exercise. We've proven over & over that that route is not within our ability it stick to.

I really don't understand why "the easy way" is perceived as a bad thing. I mean really, dont we all seek the path of least resistance in almost everything we do?[/quote']

Nobody wants to say that OTR But you are so right.

You're right.

Nobody can say it isn't easier. But I've spent 30 years yoyo dieting, at times losing up to 70 kilos. I've tried every other way. So easy way out, maybe. Last way out, probably.

I don't mind people calling it the easy way out. I certainly don't take it personally, because they haven't walked in my shoes.

I would respectfully have to dissagree. I believe the study to be inherently flawed. The simple fact that a surgery that does nothing except limit ones ability to consume food in the quantities that we once did yet produces the weight loss that we seek proves that it truly is a simple calories in vs calories burned equation.

My gastroenterologist told me the sleeve surgery is very different as the majority of the stomach--where lots of those hormones are made-- is removed. He said my metabolism will basically be reset, so long as I follow the post surgical directions. As someone who was on weight watchers for three years, lost 40 lbs in the first year, then lost zero in second and third years, my metabolism needs a reset.

This surgery, according to my Gastro, will allow me to change my life.

I'm sorry to say this, but I believe your Dr. is overselling you on this surgery. Don't get me wrong, the surgery absolutely works, but it is not because it changes tge way your body works, it is because of the lifestyle changes that come along with the surgery.

1. The hormone he is referring to is ghrelin. The hormone is a major component in triggering the hunger sensation. No, the sleeve does not eliminate this hormone, it does dramatically reduce its production temporarily.

2. The sleeve does not "reset" your metabolism. In fact as you lose weight your Base Metabolic Rate (BMR) will actually slow.

Please understand. This is NOT a magic surgery that changes how your body processes food. It is a restrictive procedure that encourages and eases lifestyle change. Nothing more.

You are correct in that you have to follow the rules. However, I have followed rules and did not lose weight. My doc, who is very well respected and who saved my life some years ago, assures me that the tool of surgery alters more than stomach size, enabling rule followers like me to lose weight. It's not magic, but it creates real biological change allowing diets to work.

I've heard this too....many times. But I've yet to see any documentation of how it works. If there is some change taking place at the metabolic level due to hormonal changes after surgery, some one please put up a link to that information because I've never found it. I do think that the change in behavior makes for success. What the sleeve does is give you a fighting chance by reducing the hunger that most of us have always given in to, and by reducing the capacity to eat long enough to learn new eating behaviors. It's also a fact that the post sleeve diet of lower carbs and higher Protein helps tremendously in reducing appetite, and putting our bodies into a fat burning stage rather than a fat storing stage. Many of us ate way too many starches before surgery which only helped us store fat regardless of how many or how few calories we ate. There is very little room in the post surgical diet for those starches, which helps keep our blood sugar levels in check, which in turn promotes fat burning.

A quick google search found this study, which is essentially what my doc said : http://doctorsofweightloss.com/can-the-sleeve-be-a-metabolic-procedure-5645

I make no assertions as to its validity, but I like it! And I will continue to do some research.

      Day 1 of pre-op liquid diet (3 weeks) and I'm having a hard time already. I feel hungry and just want to eat. I got the protein and supplements recommend by my program and having a hard time getting 1 down. My doctor / nutritionist has me on the following:
      1 protein shake (bariatric advantage chocolate) with 8 oz of fat free milk 1 snack = 1 unjury protein shake (root beer) 1 protein shake (bariatric advantage orange cream) 1 snack = 1 unjury protein bar 1 protein shake (bariatric advantace orange cream or chocolate) 1 snack = 1 unjury protein soup (chicken) 3 servings of sugar free jello and popsicles throughout the day. 64 oz of water (I have flavor packets). Hot tea and coffee with splenda has been approved as well. Does anyone recommend anything for the next 3 weeks?

        All I can tell you is that for me, it got easier after the first week. The hunger pains got less intense and I kind of got used to it and gave up torturing myself by thinking about food. But if you can, get anything tempting out of the house and avoid being around people who are eating. I sent my kids to my parents' house for two weeks so I wouldn't have to prepare meals I couldn't eat. After surgery, the hunger was totally gone.
