New Fat Tax on Sodas

Leaders in New York are proposing a new fat tax on the soft drink industry, claiming that sodas are to blame for obesity in the United States. Public officials in New York and other states see the tax as an opportunity to have an affect on the diets of the general population and cut health costs due to obesity.

It is estimated that almost 20 percent of children in the United States between 6 and 19 years old are obese, which increases the risks of diabetes, heart disease, stroke, and premature death. Health experts say that insufficient exercise, fast food, and sugary sodas are to blame.

Beverage companies says that they have reduced calories in schools by removing full-calorie soft drinks and offering lower-calorie, more nutritious, and smaller-portion options. Leading beverage companies, including Coca-Cola and PepsiCo say that 88 percent less calories are now sold in their drinks when compared to 2004.

New Plate Weighing Scale to Help Fight Obesity

A new device has been created by the scientists at Sweden’s Karolinska Institute to help fight childhood obesity. It is called a Mandometer and the device has an electronic scale that would sit under the plate and weigh the remaining food as the meal is eaten. Next to the device would be a small screen that would show a graph indicating the rate that the food is being eaten. The line on the graph would be matched against an ideal graph of consumption. If there is too much deviation from the ideal graph, the computer will make a spoken request for the eater to slow down. The concept of the device is to train overweight people to eat less and more slowly to help them feel full without overeating.

Researchers at the Bristol Royal Hospital for children and the University of Bristol in Western England did a test on 106 obese patients aged between nine and seventeen years old. The patients used the Mandometer, exercised 60 minutes a day, and followed a healthy diet for a year and had successful results. The Mandometer helped the patient’s portion sizes to be smaller by the end of the study and caused a reduction in the speed of eating by 11 percent. The Mandometer gives the best results when used in conjunction with exercise and a healthy diet.

Treat Urinary Incontinence with Weight Loss

Urinary incontinence is the unintentional release of urine and it affects more than 13 million women in the United States. Obesity is a common risk factor for urinary incontinence. A research study done by the University of Alabama-Birmingham found that overweight women who lost just 3 pounds cut the amount of leaks due to urinary incontinence by 28 percent. Women who lost 17 pounds cut the amount of leakage by 47 percent.

Scientists Developing Foods To Help You Lose Weight

At the Institute of Food Research in Norwich, England, foods are being developed that would help a person lose weight by slowing down the digestive system and triggering a signal to the brain to suppress appetite. It would control appetite by tricking the brain into thinking that you have eaten too much when you actually haven’t. The products could possibly be sold on the market in a few years.

Scientists at the University of Newcastle are testing a seaweed extract called alginate that would reduce fat absorption by cutting the level of glucose that is digested by the body before it is broken down in the large intestine. In taste testings done with several dozen people, it is found that most people felt that the foods enhanced by alginate tasted as good or even better.

Scientists in North America and Europe are developing products to control appetite, such as chemical injections and implantable devices that would interfere with the digestive system. It is not certain if appetite controlling foods could cure all cases of obesity.

Weight Gain Genes

It is found that overeating is related to the same gene involved in alcoholism and drug addiction. People who carried a certain variant of the gene and who used food to motivate themselves were the highest at risk for eating too many snacks when compared to people who had only one or neither of these traits. People with this gene variant could have a lack in reward-signaling in the brain and have to participate in more of the behavior to get as much pleasure as people with normal signaling. Exercising is something more positive that can release the same reward chemicals in the brain.

Negative Effects of Not Getting Enough Sleep

There are negative effects of not getting enough sleep each night. Not getting enough sleep each night can lead to obesity, heart disease, and illnesses.

Research has proven that people who get less than seven hours of sleep each night are 30 percent more likely to be obese. Not getting enough sleep affects the flow of hormones that regulate hunger and satiety, which can cause a person to eat more. Sleepy people are also more likely to eat high-fat and high-calorie foods to give them energy.

Women that get less than five hours of sleep each night are more likely to develop hypertension, which is a leading cause of heart disease. When a person doesn’t get enough sleep, their body produces more stress hormones and other substances that would increase inflammation, which increases the risks of heart disease and stroke.

People that get less than five hours of sleep each night also have two and a half times the risk of getting diabetes when compared to people that sleep for seven or eight hours each night. Not getting enough of deep sleep decreases the ability to regulate blood-sugar levels.

People that are sleep deprived often feel cranky because that would make the amygdala, the part of the brain that process emotional events, to go into overdrive and the prefrontal cortex, the part of the brain that regulates reasoning, to become deactivated and this would make a person feel less stable than usual. Sleep deprivation makes the brain unable to put emotional experiences into context and produce rational responses.

Sleep deprivation affects how well the body fights infections and determines how well the body produces antibodies after a vaccination. While a person is sleeping, the body produces cytokines, chemicals that help the immune system fight off infection and disease.

Weight Reduction to Treat Diabetes

It is found that weight reduction surgery works better than standard medical therapy to treat type 2 Diabetes in people who are obese. The surgery is also recommended for people who are not morbidly obese but still overweight.

In a recent study, researchers monitored two groups of obese people with type 2 diabetes. Half of the people had gastric binding done, where surgeons put a silicone strap around the stomach so that less food goes into it. The other half of the people was put on a standard diet and exercise plan. After two years passed, the people on the diet lost an average of 3 pounds while the people who had surgery done lost an average of 46 pounds. 22 of the people that had surgery also had their diabetes go into remission while only 3 of the dieters had that happen.

Video Game Tax to Fight Obesity

A New Mexico legislator has proposed a new tax on video games and televisions to try to fund a fight against childhood obesity. The bill, called “Leave No Child Inside,” would levy a 1 percent tax on some home-recreation devices and use the money to fund outdoor programs for children. It is estimated that twenty five percent of New Mexico’s children are overweight or obese.

Amount of Sleep Connected to Childhood Obesity

A Harvard study has found that babies and toddlers that sleep less than 12 hours each day are more at risk for being overweight in preschool. The link between sleep and obesity affects young children too, as well as teenagers and adults. Children that slept the least and watched the most amount of television had the greatest chance of obesity.

Previous studies have found that people that don’t get enough sleep produce more ghrelin, which is a hormone that promotes hunger. They also produce less leptin, which is a hormone that signals to the body that they are full and have had enough to eat. Watching television promotes obesity because it can take time away from doing activities that burn calories. The more active a child is the better they will sleep at night.

It is good advice to create a regular schedule for sleep for children and babies. Infants can be taught to sleep on their own by putting them to bed when they are drowsy but not completely asleep.

Study Shows that Alcohol Increases Risk of Cancer

A recent study has show that alcohol can increase the chances of getting breast cancer in women. Studies have shown a link between drinking alcohol and breast cancer but they have yet to determine if certain types of alcohol is more dangerous than others.

The study analyzed the drinking habits of 70,033 women and asked them various questions during health exams between the years 1978 and 1985. By the year 2004, 2,829 of those women had been diagnosed with breast cancer. The study found that women who had one or two drinks a day increased their risk by 10 percent and women who had more than three drinks a day increased their risk by 30 percent.

Experts think that alcohol raises hormone levels in the blood to levels that could cause cancer. Doctors say that other factors, such as genetics, obesity, and age are more important factors that can raise the risk of breast cancer.

Obesity Virus

It is reported that when human stem cells are exposed to a common virus they turn into fat cells. The cells didn't just change, but they stored fat too. It proves that some cases of obesity could be caused more than just a big appetite and not enough physical activity.

For several years, researchers looked for a link between obesity and the adenovirus-36. They found that a higher percentage of fat people were infected with the virus than non fat people. When they exposed animals to the virus, the animals fattened up. The found a gene in the virus that caused animal to get obese. The also took fat tissue from people who had liposuction and removed adult stem cells from the tissue and exposed the cells to the virus in the lab. More than half of the stem cells turned into fat cells.

If there is a vial cause to obesity, a vaccine could be created within the next 5 to 10 years to prevent the virus from making some people fat.
