Exercise shows opposing effects on appetite

Good morning friends. Exercise seems to simultaneously make people hungrier, yet more readily satisfied by a meal -- and differences in these responses from person to person may help explain why some exercisers shed pounds more easily than others, researchers say.

In a study of 58 overweight and obese adults who started an exercise regimen, researchers found that exercise tended to boost participants' hunger before a meal, compared with their sedentary days.

On the other hand, they were also more easily satisfied by their morning meal than they had been before becoming active.

But while both effects were generally at work across the study group, there were subtler differences between participants who were more successful in their weight loss and those whose extra pounds stubbornly hung on.

In general, exercisers who did not meet their expected weight loss were both hungrier after fasting -- that is, right before breakfast -- and throughout the day, compared with their hunger ratings at the study's start.

In contrast, those who were more successful in shedding pounds generally saw their pre-breakfast appetites increase after becoming active. But they were not hungrier throughout the day.

"The reason that some people are more successful (at weight loss) could be due to a lesser increase in appetite and the prevention of an increase in food intake," lead researcher Dr. Neil King, an associate professor at Queensland University of Technology in Brisbane, Australia, told Reuters Health in an email.

But the bottom line for new exercisers, he said, is that they should not throw in the towel if they start feeling more hungry than normal -- or fail to shed as many pounds as they'd been hoping.

Other research shows that exercise has health benefits -- like improved cardiovascular fitness, and lower blood pressure and cholesterol -- even if weight loss is modest.

For the current study, published in the American Journal of Clinical Nutrition, King's team had 58 overweight men and women go through a 12-week supervised exercise regimen designed to burn 500 calories per session.

At the beginning and end of the study, participants were given a breakfast of cereal and toast, and were asked to rate their hunger before the meal, immediately after and throughout the rest of the day.

After 12 weeks, 32 participants had lost the expected amount of weight based on the calories they burned during exercise; 26 had not. On average, both groups showed a revved up appetite before breakfast on week 12, but daily hunger was greater in those who had not lost a substantial amount of weight.

Both groups of exercisers, though, seemed to be more readily satisfied by their breakfast than they had been before becoming active.

It's not clear why these two different appetite effects arise from exercise. But physical activity, while spurring hunger, may also boost the sensitivity of the body's fullness-signaling system, according to King's team.

"The key messages," King said, "are exercise is good for you, don't expect unrealistic weight loss and don't give up exercising just because of lower-than-expected weight loss." - Indian Express

Alcohol can cut risk of men's heart problem

Good morning friends. Most men usually drink alcohol. Even young ones do that. Some parents advice their children especially boys that they should not get use to drink alcohol as it is bad in the body. But there is a study that alcohol can cut risk of men’s heart problem.

Alcohol lovers have now one more excuse to say 'cheers' every day, as a new research said it can cut the risk of heart problems by almost a third in men.

The Spanish research involving more than 15,500 men and 26,000 women found that those who have about four to ten units a day can apparently even halve their risk – regardless of whether they opt for beer, wine or spirits.

Women can get some benefits too, said the study published in Heart journal, although more testing is needed.

The research involved men and women aged between 29 and 69, who were asked to document their lifetime drinking habits and followed for 10 years.

Crucially the research team claim to have eliminated the "sick abstainers" risk by differentiating between those who had never drunk and those whom ill-health had forced to quit.

This has been used in the past to explain fewer heart-related deaths among drinkers on the basis that those who are unhealthy to start with are less likely to drink, the BBC reported.
The exact mechanisms are as yet unclear, but it is known that alcohol helps to raise high-density lipoproteins, sometimes known as good cholesterol, which helps stop so-called bad cholesterol from building up in the arteries.

The study was conducted in Spain, a country with relatively high rates of alcohol consumption and low rates of coronary heart disease.

However, British experts warn the claims must not be seen as a green light to over-indulge.
Cathy Ross, of the British Heart Foundation, said:

"While alcohol could offer limited protection to one organ, abuse of it can damage the heart and other organs, such as the liver, pancreas and brain."

Robert Sutton, professor of surgery at Liverpool University, said the study had "several flaws" and must not be taken to mean high levels of alcohol can improve health.

They warned that heavy drinking can increase the risk of other diseases, as alcohol responsible for 1.8 million deaths globally per year. – Indian Express

Turmeric may help offer treatments for colon cancer, psoriasis, alzheimer's

Good morning friends. Maybe many don’t know that Turmeric may help offer treatments for colon cancer, psoriasis, alzheimer. But indeed it help.

Curcumin, an ingredient commonly found in yellow curry, is being viewed as a promising disease-fighter. Scientists are working on developing nano-sized capsules containing the curry ingredient in an effort to improve its absorption and effectiveness in the body.

Curcumin is a potent antioxidant found in the Indian spice called turmeric.

The research team is developing nano-size capsule that would boost the body's uptake of curcumin and help fight several diseases.

Trials are underway to test its safety and effectiveness in fighting colon cancer, psoriasis, and alzheimer's disease.

The digestive juice in the gastrointestinal tract quickly destroys curcumin so that little actually gets into the blood.

It is already known that encapsulating insulin and certain other drugs into structures called liposomes can boost absorption.

The scientists prepared the liposomes encapsulating curcumin and fed them to laboratory rats.
They found that encapsulating more than quadrupled absorption of curcumin, and also boosted antioxidant levels in the blood.

The researchers said that encapsulating process could be an answer to the problem of increasing curcumin's absorption in the digestive environment of the gastrointestinal tract.

The study appears in ACS' Journal of Agricultural and Food Chemistry, a bi-weekly publication. – Indian Express

Snoring may help diagnose sleep disorder

Good morning friends. Some of the people have a sleeping habit like snoring. Snoring may help diagnose sleep disorder.

Researchers have developed a computer programme, which can analyze the snoring pattern of people to help diagnose a specific sleep disorder.

Doctors at University of Queensland and the Princess Alexandra Hospital assessed the snoring of 20 patients with sleep apnoea by first recording it. Similarly, they observed another 66 potential patients.

It was found that the recordings diagnosed the condition successfully in 94 per cent of cases. "An accurate device to diagnose sleep apnoea from recordings of snoring would be extremely helpful," the Telegraph quoted Dr Neil Stanley, a sleep expert as saying.

"Many patients are told about their snoring by their bed partner, but some can go years not even realizing there is a problem, only that they are constantly exhausted.”This (method) seems to be very accurate for low level sleep apnoea.

"Such a device this could also mean that we are forced to revise upwards the number of people that we think have this condition.”At the moment the only thing many GPs think they know about this illness is that it affects fat, middle-aged men, which suggests many cases among people who do not fit that profile are not being picked up," the expert added.

Sleep apnoea can turn dangerous being linked to increased risk of high blood pressure and heart attack. The results of the study were presented at the Australasian Sleep Association Conference in Melbourne, Australia.

Fight diabetes with Tai Chi

Good morning friends. There is one good way to fight diabetes. We know that diabetes is a hereditary ailment so we have to be careful for those families who have this kind of disease. For those who were not much of exercise this will make you interested with.

Doing tai chi exercises regularly can help diabetics lower their blood glucose levels, says a new study.

Tai chi is an ancient martial art that combines deep breathing and relaxation with slow, gentle circular movements.

Adults diagnosed with type-2 diabetes, who took part in a tai chi programme two days a week, with three days of home practice for six months, cut down their fasting blood glucose levels, enhanced quality of life, including mental health, vitality and energy.

"Tai chi really has similar effects as other aerobic exercises on diabetic control. Tai chi is a low-impact exercise, less stressful on the bones, joints and muscles than more strenuous exercise," said Beverly Roberts, professor at the University of Florida (UF) College of Nursing.

Roberts studied tai chi's effect on older Korean residents with Rhayun Song of Chungham National University.

Sixty-two participants, mostly Korean women, took part in the study. Half the group participated in at least 80 per cent of two supervised sessions one hour per week, with three days of home practice for six months, and the other half served as a control group.

About 23.6 million children and adults in the US or 7.8 per cent of the population have diabetes. It occurs when the body does not produce or properly use insulin, a hormone that is needed to convert sugar, starches and other food into energy needed for daily life.

Risk factors include obesity, sedentary lifestyle, unhealthy eating habits, high blood pressure and cholesterol, a history of gestational diabetes and increased age, many of which can be reduced through exercise.

"People assume that for exercise to be beneficial you have to be huffing and puffing, sweating and red-faced afterward," Roberts said.

"This may turn people off, particularly older adults. However, we have found that activities like tai chi can be just as beneficial in improving health."

Those who completed the sessions had significantly improved glucose control and reported higher levels of vitality and energy. - AhmedabadMirror

10 superfoods for shedding weight

Good morning friends. It's time for a new slim-down funda: Eat more to weigh less. Eating the right foods help you shed weight by increasing your calorie burn and cutting down food cravings.

1. Steak : Contrary to popular perception, eating a beef steak may help you drop weight. In a study published in The American Journal of Clinical Nutrition, women on a diet that included red meat lost more weight than those eating equal calories but little beef. The protein in steak helps you retain muscle mass during weight loss.

2. Eggs : Dig in to eggs, yolks and all: Eggs do not harm your heart, they can help you trim inches. Women on a low-calorie diet who ate an egg with toast and jelly each morning lost twice as much weight as those who had a bagel breakfast with the same number of calories but no eggs, a study from Louisiana State University in Baton Rouge reports. Egg protein is filling, so you eat less later in the day.

3. Oats : "Oatmeal has the highest satiety ranking of any food," Grotto says. Unlike many other carbohydrates, oats—even the instant kind—digest slowly, so they have little impact on your blood sugar."

4. Lentils : Lentils are a great tummy flattener. "They're high in protein and soluble fiber, two nutrients that stabilize blood sugar levels," says Tanya Zuckerbrot, R.D., author of The F-Factor Diet (Putnam Adult). Eating them helps prevent insulin spikes that cause your body to create excess fat, especially in the abdominal area."

5. Apples : An apple a day can keep weight gain at bay, finds a study from Penn State University at University Park. People who chomped an apple before a pasta meal ate fewer calories overall than those who had a different snack. Apples are high in fibre—4 to 5 grams each—which makes them filling. Plus, the antioxidants in apples may help prevent metabolic syndrome, a condition marked by excess belly fat or an "apple shape."

6. Chiles : A great reason to spice up your meals: You'll increase your metabolism. A compound in chiles called capsaicin has a thermogenic effect, meaning it causes the body to burn extra calories for 20 minutes after you eat the chiles. Plus, "you can't gulp down spicy food. Eating slowly gives your brain time to register that your stomach is full, so you won't overeat.

7. Yogurt : Dietitians often refer to plain yogurt as the perfect food. With its trifecta of carbs, protein and fat, it can stave off hunger by keeping blood sugar levels steady. In a study from the University of Tennessee, people on a low-calorie diet that included yogurt lost 61 per cent more fat overall and 81 per cent more belly fat than those on a similar plan but without yogurt.

8. Parmesan : Women who had one serving of whole milk or cheese daily were less likely to gain weight over time, a study in The American Journal of Clinical Nutrition finds. Lowfat-dairy fans didn't experience the same benefit. Whole dairy may have more conjugated linoleic acid, which might help your body burn fat.

9. Avocado : Don't let the fat content of an avocado (29 grams) scare you—that's what makes it a top weight loss food. The heart-healthy monounsaturated fat it contains increases satiety.

10. Olive oil : Like avocados, olive oil has healthy fat that increases satiety, taming your appetite. But that's hardly its only slimming feature. Research shows it has anti-inflammatory properties. - The Times of India

Green tea cuts heart disease risk

Good morning friends. Those of you who love to drink tea, specially the green one. You will have a good benefit on that now. Green tea cuts heart disease risk .

Two mugs of green tea every day can significantly reduce the risk of dying from cardiovascular disease, claims a new study.

To reach the conclusion, researchers from Okayama University tracked the health of more than 12,000 elderly people living in Japan. The men and women were aged between 65 and 84. In the study, the volunteers were asked to fill out questionnaires on lifestyle factors including details of diet, smoking and alcohol intake, reports The Daily Express.

During the following seven years more than 1,200 of the volunteers died. However, when all questionnaires were analyzed, scientists found that the more green tea the participants had drunk, the less likely they were to have died. This, especially, was true of cardiovascular disease.

Those drinking between 420ml and 560ml a day were up to 75 per cent less likely to have died of heart or circulatory­ disease than those who drank less than one cup each day. The study has been published in the Annals of Epidemiology. - The Times of India
