Doctor urges an end to fitness myth

BOCA RATON, Fla. (UPI) -- Constantly linking exercise with weight loss may cause more people to fail at reaching their goals, a bariatric physician suggests.

Dr. Sasson Moulavi says exercise is ideal for maintaining weight once goals are met but is usually counterproductive in trying to lose weight.

"I've seen far better results from patients that strictly follow a lifestyle program than those that work to incorporate exercise into their weight loss regime," Sass says in a statement. "When you exercise, your body certainly burns calories, but it also creates hunger and compensates with food, which is counterproductive."

When people exercise, they burn calories and feel justified in eating a little more here and there, which can sabotage their efforts because many eat more calories than they burned, Moulavi says.

For example, a study published last year in the International Journal of Obesity, found during the 18-month study of 538 students "when the kids start to exercise, they end up eating more -- an average of 100 calories more than they had just burned," Moulavi says.

Moulavi recommends eating healthy, nutritious foods, getting the weight off and then focusing on an exercise routine to keep it off.

Study: Cellphone use fights Alzheimer's

TAMPA, Fla. (UPI) -- U.S. researchers say they're surprised to discover radiation from cellphones may protect against and even reverse Alzheimer's disease.

The researchers at the Florida Alzheimer's Disease Research Center, led by University of South Florida neuroscientist Gary Arendash, said exposing old Alzheimer's mice to electromagnetic waves from cellphones erased brain buildups of a harmful protein known as beta amyloid and eliminated memory problems typical of Alzheimer's.

The radiation also prevented beta amyloid buildup in younger Alzheimer's mice, the researchers said in a study funded in part by the National Institute on Aging and published in the Journal of Alzheimer's Disease.

In fact, exposing normal mice to cellphone radiation for two hours a day over seven to nine months actually improved their cognitive abilities compared with so-called control mice tested in a parallel experiment for comparison, Arendash and colleagues said.

The highly controlled study let researchers isolate the effects of cellphone exposure on memory from other lifestyle factors such as diet and exercise, the researchers said.

It involved 96 mice, most of which were genetically altered to develop beta amyloid plaques and memory problems mimicking Alzheimer's disease as they aged.

"It surprised us to find that cellphone exposure, begun in early adulthood, protects the memory of mice otherwise destined to develop Alzheimer's symptoms," Arendash said. "It was even more astonishing that the electromagnetic waves generated by cellphones actually reversed memory impairment in old Alzheimer's mice."

Kitchen spoon size determines drug amount

ITHACA, N.Y. (UPI) -- Parents who use kitchen spoons to measure liquid medicine for a child may over or under medicate, New York researchers found.

Study leader Dr. Brian Wansink -- director of the Cornell Food and Brand Lab and author of "Mindless Eating: Why We Eat More Than We Think" -- previously found smaller plates can unknowingly decrease how much people eat.

For the liquid medicine study, former cold and flu sufferers were asked to pour one teaspoon of nighttime flu medicine into kitchen spoons of differing sizes. Depending upon the size of the spoon, the 195 former patients poured an average of 8 percent too little or 12 percent too much medicine.

"When pouring into a medium-size tablespoon, participants under dosed. But when using a larger spoon, they poured too much medicine," Wansink says in a statement. "Twelve percent more may not sound like a lot, but this goes on every four to eight hours, for up to four days -- so it really adds up -- to the point of ineffectiveness or even danger."

Study co-author Dr. Koert van Ittersum of the Georgia Institute of Technology says people cannot always trust their ability to estimate amounts. Wansink and van Ittersum recommend using a measuring cap, a dropper, or dosing spoon, or syringe to to measure liquid medicine.

The findings are published in the Annals of Internal Medicine.

Expert: Pain management failing millions

CORVALLIS, Ore. (UPI) -- Millions with chronic pain are under treated due to inadequate physician training, personal biases or fear of drug abuse, a U.S. pharmaceutical expert says.

Kathryn Hahn of the College of Pharmacy at Oregon State University says adequate pain treatment is not a major part of most physicians' medical training. Even though they will often see a stream of patients with pain problems throughout their careers, doctors may only get a few hours of education on the use of opioids in medical school.

"We have more sophisticated pain management techniques available now than ever before, but many doctors are not fully informed about all the options available, and also often turn patients away because they're very concerned about the problems with prescription drug abuse," Hahn says in a statement.

Hahn suggests:

-- Doctors and nurses should accept that patients are the final arbiter of what is painful, believe them and work with them on their concerns.

-- Individuals should work and communicate patiently with their healthcare providers, not switch doctors arbitrarily, educate themselves if necessary, but be persistent in having their pain concerns taken seriously.

-- Consumers must acknowledge the seriousness of the prescription drug abuse issue and lock up their medications securely, literally in a home safe in some circumstances. The unlocked medicine cabinet is the foundation of a cottage industry of drug abuse in America today.
