Dieters have long sworn that grapefruit helps them lose weight. The Grapefruit Diet, also called the Hollywood Diet, dates back to the 1930s and has a host of celebrity fans including singer Kylie Minogue. It involves having grapefruit or grapefruit juice with every meal while cutting back on calories.
Now, scientists are beginning to believe them.
A study has found that drinking grapefruit juice when eating fatty food lowers the amount of weight put on by up to a fifth.
The research also suggested that grapefruit could be as good as prescription drugs at keeping blood sugar levels under control—a key part of managing diabetes.
The experiments were conducted on mice—but researchers say the results are true for humans. Professor Joseph Napoli, of the University of California, Berkeley, said, “We see all sorts of tricks about nutrition. But these results, based on controlled experiments, make it necessary to study the potential health-promoting properties of grapefruit juice further.”
The researchers found that when the mice were fed fatty food for three months, those given grapefruit juice to drink gained up to 18 percent less weight than those given water.
They also had lower blood sugar and insulin levels—despite eating the same number of calories and doing the same amount of exercise as the mice who drank water. In fact, grapefruit juice was as good at controlling insulin as the widely used diabetes drugs, the journal PLOS ONE reports.
However, the fruit juice only had an effect on weight when the animals ate fatty food. The researchers said they did not know how grapefruit stops the pounds from piling on.
Spokesman Mariette Abrahams, a dietician, said until then it is too early for people to try grapefruit diets. “Grapefruit should be part of a healthy balanced diet, but it shouldn’t be the focus of the diet.” she said.

“I want to give a message,” Barbara Walters said. “If you have kids who are smoking, tell them that we lost Peter.”
Lung cancer is the worst killer in America, taking more lives each year than any other cancer, according to the America Cancer Society. About 160,440 Americans die each year of cancer, making up 28 percent of all cancer deaths. More than 87 percent of lung cancers are smoking related.
Dr. Derek Raghavan, director of the Cleveland Clinic’ s Taussing Cancer Center(陶西格癌症中心), said that once a person stops smoking, he starts getting better. Three to five years after quitting, the possibility of getting lung cancer is reduced by half.
Warning signs of lung cancer can also be mixed with symptoms connected with long-term smoking. The three main warning signs are an increase of coughing that doesn’t clear up, coughing up blood and sharp chest pains.
People with those symptoms should see a doctor. Raghavan said there have been promising developments in the treatment of lung cancer, including uses of radiation and surgery and drugs. “But the fact is that stopping smoking is the most important thing we can do,” Raghavan said. “There is no treatment that even comes close.”

Yoga for Weight Loss
Yoga is a form of exercise that uses your large muscle groups and raises your heart rate, and it is beneficial for weight loss. Practising yoga can help you burn calories long after you hit the mat, even if you don’t do more intense(剧烈的) forms of yoga. That’s because yoga’s other benefits can help with weight loss too.
Yoga helps manage stress, and studies show that high levels of cortisol, a stress hormone(荷尔蒙), can lead to an increase in fat and reduce your muscle mass. Yoga has an effect on the body’s stress response and reduces the production of hormones linked to weight gain, such as cortisol.
