Forget stomach stapling and lap band surgery. The next big thing in weight loss surgery may be the stomach pacemaker A device that acts like a pacemaker for your stomach may be able to trick your body into thinking it’s full. In a clinical trial on 65 patients, manufacturer IntraPace said most lost about 20% of their weight and kept it off. The device works like a heart pacemaker. and sends out electrical pulses to the brain that kick in just after eating. These messages notify the body that it is full after consuming a small amount of food. One person in the study said it makes him feel full after eating just half of his meal. The device was approved by the British medical community last month. Soon the device will be available across Europe The long term effectiveness of the device is not yet known.
Canada has a significantly lower rate of obesity than does the US, a new US government study has shown. More than a third of Americans are obese, compared to about a quarter of Canadians, the Centers for Disease Control (CDC) has concluded. The study found that both countries’ obesity rates have grown significantly in the past two decades. About 24% of people in Canada are obese, compared with 34.4% of U.S. citizens People who are obese, roughly 30 or more pounds over a healthy weight, are at a higher risk of developing heart disease, type 2 diabetes, cancer and other diseases. In Canada, 24.3% of men and 23.9% of women are obese vs. 32.6% of men and 36.2% of women in the U.S. Over the past two decades, the prevalence of obesity increased significantly in both the U.S., and Canada, but it’s still about 10 percentage points higher here, says Cynthia Ogden, an epidemiologist with the National Center for Health Statistics, part of the Centers for Disease Control and Prevention.

The fact that gastric bypass surgery can help waistlines is well known, but now it has been demonstrated it can help hearts as well.
According to a new study conducted by the Medical College of Georgia, overly stressed hearts due to obesity can regain form as well as function after gastric bypass surgery. The study showed that following the weight-loss surgery, hearts required less work to function normally. Led by Dr. Sheldon Litwin, the study followed 400 obese people who chose to undergo a gastric bypass surgery, and compared to 300 obese people who did not undergo the procedure. “We know obese people get cardiovascular disease more often than non-obese people. One of the questions out there is: Is it reversible if they lose weight? The answer is yes”, lead researcher Sheldon Litwin said Echocardiograms taken two years after the surgery showed a change in the heart structure in most participants. Obesity can often lead to structural changes, including excess muscle and ventricle enlargement, both of which can result in heart failure or heart disease. The new study, however, shows that weight loss can reverse them. According to Litwin, obese people get cardiovascular disease more often than non-obese people, but the new study shows that it is reversible if they manage to lose weight. In addition, participants who underwent the gastric bypass surgery also lost an average of 100 pounds, as smaller waistlines, lower blood pressure and heart rate, as well as good cholesterol levels. Litwin noted that the best way to manage weight is through an adequate diet and a healthy lifestyle. The lead author added that it is possible to lose weight just by eating better and exercising more, but generally such lifestyle changes are ineffective with people who are severely obese. In 2007, about 205,000 obese people had gastric bypass surgery in the United States. Published Feb. 18 in the Journal of the American College of Cardiology
The US government on Monday released new dietary guidelines urging all Americans to cut their daily salt intake by one-third and those over 50 to make more drastic reductions. The guidelines also suggest that consumers cut back on fats, added sugars and refined grains while eating more whole grains, fruits, vegetables, low-fat dairy products, lean meats, poultry and seafood “The 2010 Dietary Guidelines are being released at a time when the majority of adults and one in three children is overweight or obese,” Agriculture Secretary Tom Vilsack said in a statement. “This is a crisis that we can no longer ignore,” he added. The guidelines, which are updated and published every five years, also urge Americans to eat less calories and exercise more. “The bottom line is that most Americans need to trim our waistlines to reduce the risk of developing diet-related chronic disease,” Vilsack said. The new guidelines recommend reducing daily salt intake to less than 2,300 milligrams, or one teaspoon, and urge further reductions to 1,500 milligrams for people 51 and over, African Americans and those with hypertension, all of whom now account for around half of the population. The Center for Disease Control (CDC) estimates that Americans currently eat 3,466 milligrams, or about teaspoon and a half of sodium, which has been linked to hypertension and other cardiovascular disease. Most of that sodium comes from processed foods, not the salt shaker, and the government has urged the food industry to cut back as well. The guidelines can be found online at www.dietaryguidelines.gov
Walking more and losing weight can improve mobility as much as 20 percent in older, obese adults with poor cardiovascular health, according to a new Wake Forest University study. The results from the five-year study of 288 participants appear online Jan. 24 in the Archives of Internal Medicine. The combination of weight loss and physical activity is what works best. These findings run counter to the commonly held belief that it is unhealthy for older adults to lose weight. “To improve mobility, physical activity has to be coupled with weight loss,” said Jack Rejeski, Thurman D. Kitchin Professor of Health and Exercise Science. “This is one of the first large studies to show that weight loss improves the functional health of older people with cardiovascular disease.”
The World Health Organization (WHO) has called on nations to fight the growing epidemic of childhood obesity by reducing the marketing of unhealthy foods and beverages. WHO said that children worldwide are exposed to marketing of foods high in fat, sugar or salt that’s why their call for national and international action to limit children’s exposure to marketingLatest figures revealed that about 42 million children in the world under the age of five are suffering from being overweight or obesity Reportedly, each year more than 35 million people die from non-communicable diseases mostly in low and middle-income countries Experts recognize poor diet as one of the four common factors leading to cancers, diabetes, cardiovascular diseases and chronic lung diseases Dr. Timothy Armstrong, head of WHO’s efforts on promotion of healthy diet and physical education, states that non-communicable diseases are the cause of 90% of premature deaths in low to middle income countries, where obesity is a continual growing problem. In total 42 million children in the world are obese or overweight and that is in children under five years old, the United States figures have shown 22 million children under five years old and 35 million are from poor countries. Acknowledgment that the advertising of junk food and beverages rich in salt, sugar, saturated and trans fats inspire children to consume these foods. Advertising can also be used promote healthy diets, led the WHO’s assembly last May to call on the United Nations agency to prepare the recommendations. The WHO’s member states told it to work with the private sector as well as governments and civil society. The recommendations aim to tackle both the frequency of advertising and its “power” — such as the use of cartoon characters that appeal to children. Officials from WHO consulted with leading companies in the sector. Those include Coca-Cola, General Mills, Kellogg, Kraft, McDonald’s, Nestle, PepsiCo, Unilever, Grupo Bimbo, and the World Federation of Advertisers. The companies agreed to draw up a code of conduct and committed not to market unhealthy products to children under 12 years of age
