  • Human body’s natural weighing scales can now help cure obesity.
  • The study of these scales can help us understand the reasons and cures for obesity.

Human body consists of an internal body weight sensing system that operates like bathroom scales, registering body weight and signalling the brain to reduce food intake, researchers have found.

The system, which regulates weight gain by calculating body weight and fat mass, could lead to a better understanding of the causes of obesity as well as new anti-obesity drugs.

The results also explain why several studies have coupled sitting habit with obesity and bad health. It is because the “internal body scales give an inaccurately low measure when you sit down. As a result you eat more and gain weight,” the researchers said.

“We have found support for the existence of internal bathroom scales. The weight of the body is registered in the lower extremities. If the body weight tends to increase, a signal is sent to the brain to decrease food intake and keep the body weight constant,” said John-Olov Jansson, Professor at Sahlgrenska Academy, University of Gothenburg in Sweden.

Further, the results demonstrate that the weight sensing system regulates fat mass independently of leptin — a weight loss hormone. It is possible that leptin combined with activation of the internal body scales can become an effective treatment for obesity, the researchers said.

For the study, published in the journal Proceedings of the National Academy of Sciences (PNAS), the team performed experiments on obese rodents that were made artificially heavier by loading with extra weights.

The animals lost almost as much weight as the artificial load. The extra weights caused body fat to decrease and blood glucose levels to improve. IANS

Obesity can result in heart disease risk, everyone is aware of it. However, these is new way to maintain the health of your heart. Weight loss surgery can decrease the risk of heart disease, a study says.

“This is the first large-scale analysis of predictors of change in cardiovascular disease risk factors among adolescents following bariatric surgery,” said Marc P Michalsky, Professor at the Ohio State University College in the US.

Findings

Three years after surgery, teens who underwent a gastric bypass had a 27 percent drop in their BMI, similar to the 26 percent drop in those who had the sleeve gastrectomy. Pixabay

  • Bariatric or weight-loss surgery performed during adolescence may provide unique benefits.
  • It minimizes the development and progression of impaired glucose metabolism, atherosclerosis heart failure and stroke.
  • Prior to the bariatric surgery, 33% of the participants had three or more defined cardiovascular disease risk factors.
  • Three years post-surgery, only 5% of the study participants had three or more risk factors; representing significant reduction in the overall likelihood of developing cardiovascular disease later in life.
  • Not only weight loss, the surgery also reduced dyslipidemia risk among teenager — a condition marked by an abnormally increased level of cholesterol in the blood, when compared to the older people.

Methodology

  • The study was conducted on 242 adolescents who were diagnosed with hearth risk factors at the baseline.
  • Among 242 participants of the study, 161 underwent Roux-en-Y gastric bypass procedure, 67 of them underwent a vertical sleeve gastrectomy and 14, adjustable gastric banding.
  • The authors collected data from five participating medical centers for their observational study, and decisions about procedures depended on each center’s clinical practices.
  • The participants had a BMI between 34 to 88 when the study began. A BMI over 25 is considered overweight; over 30 is obese.

Conclusion

  • The obesity classification with the highest risks of health problems is a BMI of 40 or higher. Three years after surgery, teens who underwent a gastric bypass had a 27 percent drop in their BMI, similar to the 26 percent drop in those who had the sleeve gastrectomy. Those with the gastric band had an 8 percent drop in BMI.

“The study demonstrated early improvement and reduction of cardio-metabolic risk factors, offering compelling support for bariatric surgery in adolescents,” Michalsky added.

The study was published in the online journal Pediatrics. (IANS)
