New Weight Loss Technique Allows 1000 Calories per Day Without Feeling Hungry
A new study reveals a novel weight loss technique that could replace traditional bariatric surgery, say these doctors who found their patients not only could get by on only 1000 calories per day without feeling hungry and lose approximately 50% of their body weight in 6 months, but also saved thousands of dollars in treatment costs.
According to a new study published in the medical journal Clinical Gastroenterology and Hepatology, and reported in the Chicago Tribune, surgeons performing a new type of weight loss surgical technique found that their trial study patients lost approximately 50% of their body weight in 6 months without going hungry using a procedure called “Endoscopic Sleeve Gastroplasty (ESG).”
Endoscopic sleeve gastroplasty is a minimally invasive surgical procedure where rather than making a typical bariatric-related incision from outside the body in (and leaving a visible scar), an endoscope is fed through the mouth, down the esophagus and into the stomach where sutures are applied making the stomach smaller and altering its normal configuration. The end result is a “mini-stomach” that controls how much food is digested and resulting calories absorbed.
"It delays the emptying of the stomach, and food sits in it for longer periods of time. Patients will be able to follow a low-calorie diet, fewer than 1,000 calories a day, without being hungry all the time," stated study author Dr. Barham Abu Dayyeh, a gastroenterologist at the Mayo Clinic in Rochester, Minnesota for the Chicago Tribune.
Aside from the absence of a visible scar, the surgery not only leads to significant weight loss, but also at a cost of about $10,000 to $15,000, which is roughly a third of the cost of other weight-control procedures. Furthermore, the new procedure also avoids some of the common complications of the more expensive traditional bariatric surgeries.
"We're not cutting or removing any part of the stomach or digestive tract…there's a low risk of having any nutrition deficiencies, because you're leaving the gastrointestinal tract and stomach alone," stated Dr. Abu Dayyeh.
According to the published study, twenty-five obese individuals with an average BMI of 36 underwent ESG surgery at the Mayo Clinic in Rochester, Minnesota in 2012 and were then followed at 3, 6 and 9 months (with only 8 patients followed the entire 20-month study period) noting changes in body weight and any adverse events related to the surgical procedure. Four of the study participants were selected for additional analysis of solid and liquid gastric emptying, satiation (meal tolerance), and fasting and post-prandial levels of insulin, glucose, and gut hormones before and after the surgery.
What the study showed was that:
• Of the participants who completed the 20-month study, the participants lost on average slightly greater than half of their excess body weight the first six months.
• Some regain of body weight occurred by 20 months post-surgery with 3 of the remaining 8 patients, but still with significant overall weight loss.
• The surgeries resulted in three adverse events: an infection, a mildly collapsed lung and a blood clot in a lung.
Of the 4 study participants with additional testing, the study revealed:
• A decrease in caloric consumption, but with feelings of fullness.
• A slowing of gastric emptying of solids.
• A trend toward increased insulin sensitivity.
The authors of the study concluded that the ESG technique with its resulting delays in gastric emptying, inducing of early satiation, and significant reduction of body weight, that it has potential as an alternative to bariatric surgery for selected patients with obesity. Further studies are needed on a larger scale to confirm the benefits of this type of surgery over traditional bariatric surgical procedures for patients with a particular BMI.
