High-fructose corn syrup -- the most ubiquitous sweetener in the American diet -- has shared a lot of the blame for the obesity epidemic. Some nutritionists have called for a return to table sugar to sweeten sugar sodas, ketchup, and baked goods after a few studies suggested that the processed corn syrup fostered weight gain more readily than other sweeteners.

As it turns out, we probably don’t need to worry about specifically avoiding foods with high fructose corn syrup in order to lose weight: We simply need to watch our calorie intake. A new review of more than 40 studies published yesterday in the Annals of Internal Medicine found that fructose didn’t lead to any extra weight gain when it replaced sugar in the diet, though it did cause study volunteers to gain weight when it was added on top of calories.

Bottom line: If you’re trying to lose weight or avoid gaining excess pounds, stick wtih smaller portion sizes and don’t be fooled into thinking that foods sweetened with “evaporated cane juice” or plain-old sugar are any less damaging to your waistline than those sweetened with high fructose corn syrup.

Weekly challenge: cut calories, not high-fructose sweeteners to lose weight

A popular misconception is that overweight or obese people have a slower metabolism.

BAD news for people trying to lose weight. A new assessment of how the body responds to dieting shows that it is about twice as difficult as previously thought to shed fat.

The calculations also puncture the myth that cutting calories will lead to continued weight loss. In fact, the effect of reducing the intake of calories levels off after about three years, scientists said.

Obesity experts had previously suggested that cutting 100 kilocalories a day from the diet for six months would lead to the loss of about 5lb in weight. But it turns out that this amount of weight loss is more likely to take a year and that any further weight loss will reach a plateau after three years, rather the continuing forever at the same rate.

"People have used this rule of thumb for how to lose weight for decades and it turns out to be completely wrong," said Kevin Hall, a mathematical modeler at the US National Institute of Diabetes and Kidney Diseases in Maryland.

"The reason it's wrong is that it doesn't account for the metabolic changes that take place when people change their diet. If you cut the calories in someone's diet, the metabolism slows down and it slows down the more weight that is lost until it reaches a plateau."

A popular misconception is that overweight or obese people have a slower metabolism, which would mean that they do not burn off the calories as fast as leaner people. In fact, the fatter someone is, the higher their metabolism is likely to be be, Dr Hall told the American Association for the Advancement of Science.

"Unlike the popular notion out there that heavier people have slower metabolism, the heavier you are the more calories you are burning," he said. "And the more of that mass is lean tissue compared to fat tissue, the more calories still you are burning - and obese people tend to have both an elevated fat mass and an elevated lean-tissue mass."

American scientists have used the new assessment to build a mathematical model of how the human body responds to variations in the intake of food energy.

The model allows people to use a website to calculate for their own age, sex and body weight how many calories they need to cut out from their diet in order to achieve a target weight loss.

"Using the old system, someone who cut 100 calories a day could expect to lose 5lb in six months," Dr Hall said. "Under the new system, it would take a year to lose this 5lb - making it twice as difficult. The rule of thumb is cutting 10 kilocalories per day from your diet for every pound you want to lose."

Dr Hall said that giving people unrealistic expectations of how easy weight loss is can itself be dispiriting if the advice turns out to be wrong.

Researchers at the University of Liverpool have found that overweight dogs that lose weight have an improved quality of life compared to those that don't.

It is estimated that approximately a third of the UK dog population is obese. Obesity is a serious disease and can lead to many other health disorders including diabetes, heart disease and arthritis.

A study of 50 overweight dogs, comprising a mix of breeds and genders was undertaken by scientists at the University in collaboration with the University of Glasgow, Royal Canin and the WALTHAM Centre for Pet Nutrition.

Owners completed a questionnaire to determine the health-related quality of life of their dog prior to weight loss. A follow-up questionnaire was completed by the owners of 30 dogs that successfully completed the weight loss programme, enabling changes in quality of life to be assessed. A range of life quality factors were scored, including vitality, emotional disturbance and pain. The quality of life of dogs which succeeded with their weight loss programme was also compared with those dogs that failed to lose weight successfully.

The results showed that the quality of life improved in the dogs that had successfully lost weight, in particular vitality scores increased and the score for emotional disturbance and pain decreased. Moreover, the more body fat that the dog lost, the greater the improvement in vitality.

The research also found that dogs that failed to complete their weight loss programme had worse quality of life at the outset than those successfully losing weight, most notably worse vitality and greater emotional disturbance.

Dr Alex German, Director of the Royal Canin Weight Management Clinic at the University, said: "Obesity is a risk for many dogs, affecting not only their health but also their quality of life. This research indicates that weight loss can play an important role in keeping your dog both healthy and happy."

Dr Penelope Morris, from the WALTHAM Centre for Pet Nutrition, added: "Strategies for combating obesity and keeping dogs fit and healthy include portion control, increased exercise and diets specifically formulated for overweight pets."

Established in 2004, the Royal Canin Weight Management Clinic at the University's Small Animal Hospital UK's is the world's first animal weight management referral clinic and was set up to help tackle and prevent weight problems in animals such as dogs and cats.

Veterinary surgeons from any general practice in the UK can refer overweight animals to the clinic. The patients receive a thorough medical examination, and are then given a specific dietary plan and exercise regime to follow over several weeks.

Excerpt from:
Quality of life of obese dogs improves when they lose weight

By Karen Rowan
MyHealthNewsDaily

If you want to know whether you’ll lose weight or not, don’t ask a doctor.

In a new study, physicians predicted about 55 percent of patients would be "likely" or "very likely" to follow their recommendations for losing weight, eating healthier or getting more exercise. But three months later, only 28 percent of patients had lost at least two pounds, 34 percent were eating less fat and more fiber, and 6 percent were getting in one more hour of brisk walking each week.  

It was surprising, researchers said, that in slightly more than half of cases, doctors said they believed their patients would follow their recommendations, because other work has not shown that physicians have that level of optimism about their patients' behaviors.

Why the optimism? While physicians generally think patients are unlikely to follow recommendations, after talking with any given patient, doctors become optimistic that the patient will change, the study researchers say.

The findings were published Feb. 7 in the journal Family Practice.

Recordings of doctor's appointments

More than 60 percent of Americans are overweight or obese, according to the Centers for Disease Control and Prevention.

In the study, the researchers made audio recordings of conversations between 40 doctors and 461 of their overweight or obese patients. The doctors and patients knew their conversations were being recorded, but were told only that the study they were participating in would look at how doctors "addressed disease prevention" with their patients — not that weight loss goals would be looked at, specifically.

After each visit, physicians were asked questions such as: How likely will the patient follow your weight loss recommendations?

When considering the patients who the doctors said would likely improve, most of the time, the docs got it wrong. Only 16 percent of those predicted to lose weight actually lost weight over the next three months. Of those that the doctors predicted would follow their healthy eating recommendations, only 19 percent actually improved their eating habits. Four percent of those predicted to get more exercise actually started doing so.

The physicians were more often accurate in their guesses about who not improve.

While previous studies had surveyed physicians about their expectations for their patients in general, none had asked doctors what they thought about specific patients immediately after an office visit, according to the study.

Is optimism good?

Doctors' expectations about their patients ability to change is important, because a doctor with low expectations "can lead to patients being less likely to improve their behaviors," the researchers said. When patients don’t improve behaviors, doctors' expectations only sink even lower, and a vicious cycle ensues.

But physician optimism might have some bene?ts. "Patients might feel more con?dent that they can lose weight when they feel their physician believes they will change," the researchers wrote. However, this optimism might mean that the doctors are overestimating the effect their recommendations will actually have on patients, and could make doctors less receptive to learning effecting techniques for counseling patients, according to the study.
